タイムライン

  • 00:00:00 - 00:05:00

    The speaker introduces the concept of 'lyic friction,' describing the challenge of getting out of bed due to fatigue or lack of motivation. Using top-down control mechanisms allows individuals to override these feelings by either appealing to love, obligation, or inner strength. The effectiveness of this control increases with restfulness.

  • 00:05:00 - 00:10:00

    The speaker highlights that overriding 'lyic friction' can also be a skill honed over time. Rested individuals are better equipped to exert top-down control, leading to greater accomplishments. The mental narrative related to personal goals can motivate individuals, suggesting that familiarity with success can help overcome inertia.

  • 00:10:00 - 00:15:00

    The discussion continues on the nature of delayed gratification and its connection to dopamine release. It is explained that knowing the future reward can evoke a positive anticipation, which aids in engaging the necessary willpower to overcome 'lyic friction.'

  • 00:15:00 - 00:20:00

    The speaker contrasts top-down control as a mechanism for overriding cravings, emphasizing the subjective nature of motivation and the importance of knowing what success feels like. Instances of athletes are cited to illustrate how anticipation of success can build motivation to push through immediate discomfort.

  • 00:20:00 - 00:25:00

    A transition into discussing the neuroplasticity of attention emphasizes that focusing increases as one forces themselves to concentrate. Acknowledging the role of substances like caffeine, which artificially heighten alertness, suggests that achieving focus can often be tackled through mental strategies rather than biological hacks alone.

  • 00:25:00 - 00:30:00

    The speaker humorously references third-person self-talk as a method to overcome 'lyic friction.' They promote the value of viewing oneself as a future successful individual to motivate actions in the present, illustrating this with a personal anecdote about an enjoyable ocean dip despite initial reluctance.

  • 00:30:00 - 00:35:00

    The importance of experiencing rewards, or 'wins,' is introduced. The speaker suggests that too many predictable rewards can lead to diminished dopamine responses, advocating for intermittent rewards—akin to concepts used in casinos to maintain interest and motivation.

  • 00:35:00 - 00:40:00

    Following anecdotes on work habits, the speaker stresses the significance of varying one’s environmental conditions (e.g., reducing caffeine or distractions) to allow for effective learning and focus, inadvertently facilitating peak performance.

  • 00:40:00 - 00:45:00

    The conversation touches on the evolving nature of individuals learning how to balance focus and relaxation efficiently, citing structured learning methods enhanced by rest, emphasizing that neuroplasticity requires both engagement and downtime to thrive.

  • 00:45:00 - 00:55:05

    Concluding remarks highlight the foundational role of sleep in all cognitive and emotional processes, reinforcing that focused work and relaxation must be meticulously balanced to optimize productivity and mental health, along with practical tips to manage energy levels throughout the day.

  • 00:00:07
    there's a certain friction I actually
  • 00:00:09
    call this lyic friction where let's say
  • 00:00:11
    you don't want to get out of bed in the
  • 00:00:13
    morning you just don't maybe you're
  • 00:00:14
    tired but maybe you're just not
  • 00:00:15
    motivated and you force yourself to get
  • 00:00:17
    up what you're doing is you're using top
  • 00:00:19
    down control to say h the fatigue I feel
  • 00:00:21
    I'm going to override that fatigue and
  • 00:00:24
    much of what's online is how do you
  • 00:00:27
    override that fatigue that lack of
  • 00:00:29
    motivation and some people say well you
  • 00:00:30
    got to do it out of love and then other
  • 00:00:32
    people say you do it out of anger and it
  • 00:00:34
    doesn't matter these top down mechanisms
  • 00:00:36
    are very subjective if you are going to
  • 00:00:39
    do it because you really care about the
  • 00:00:40
    person that you're going to pick up at
  • 00:00:41
    the airport and you got to get up early
  • 00:00:43
    well that's one mechanism if you're
  • 00:00:45
    going to do it because um you're a
  • 00:00:47
    person of your word and you said you
  • 00:00:48
    were going to be there and you do it you
  • 00:00:49
    know the the just do it Mantra is top-
  • 00:00:52
    down control okay now just the top- down
  • 00:00:55
    control is also involved in controlling
  • 00:00:58
    reflexes that desire to consume
  • 00:01:01
    something that isn't good for you you
  • 00:01:03
    can resist that desire through top- down
  • 00:01:05
    control the more rested you are
  • 00:01:07
    generally the easier it is to engage top
  • 00:01:09
    down control so when I look at people um
  • 00:01:12
    like I I don't know Ronda Rousey I don't
  • 00:01:14
    know too much of her story but I do know
  • 00:01:15
    David he's been to my lab and um I
  • 00:01:18
    endorsed his book and I'm obviously
  • 00:01:19
    super impressive David God needs no
  • 00:01:21
    introduction super impressive and I
  • 00:01:23
    think one of the many important things
  • 00:01:24
    that David stands for is the ability to
  • 00:01:26
    override lyic friction to talk to to
  • 00:01:30
    convince himself to do it anyway and
  • 00:01:33
    there are others uh that do this have
  • 00:01:34
    talked about this as well that is top
  • 00:01:37
    down control and what they've what he's
  • 00:01:39
    done if I may I don't I've never uh I've
  • 00:01:42
    never actually figured this out
  • 00:01:44
    conclusively but I have a strong sense
  • 00:01:47
    that what he's done is he's somehow
  • 00:01:49
    gotten very familiar with The Narrative
  • 00:01:53
    of friction or the experience of
  • 00:01:55
    friction and The Narrative of overriding
  • 00:01:57
    friction and he knows that a win is
  • 00:01:59
    coming lateer
  • 00:02:00
    and so what happens is if you know that
  • 00:02:03
    that overriding lyic friction is going
  • 00:02:05
    to create a wind down the line that wind
  • 00:02:07
    could be a sense of accomplishment that
  • 00:02:09
    you conquered something in this lyic
  • 00:02:10
    friction so you need to know what that
  • 00:02:12
    that accomplishment looks like you need
  • 00:02:14
    to exper it helps to know what the wind
  • 00:02:17
    feels like yes and what you can do is
  • 00:02:19
    you can start to thread back that
  • 00:02:22
    dopamine from the future to the idea by
  • 00:02:26
    getting out of bed I'm already starting
  • 00:02:28
    to experience the wind you can
  • 00:02:29
    anticipate the win now there's actually
  • 00:02:31
    a paper that was just published on this
  • 00:02:33
    as a good timing for this question which
  • 00:02:35
    is that really points to the fact that
  • 00:02:38
    delayed
  • 00:02:39
    gratification is controlled by dopamine
  • 00:02:42
    it's a somewhat complex paper so I don't
  • 00:02:43
    I don't want to get into the details but
  • 00:02:45
    what it shows is that if you know that
  • 00:02:47
    by delaying gratification you are going
  • 00:02:49
    to um it's worthwhile you start to
  • 00:02:52
    achieve that dopamine increase earlier
  • 00:02:55
    so delayed gratification is as it sounds
  • 00:02:57
    is you know resisting
  • 00:03:00
    the urge resisting the chocolate bar or
  • 00:03:01
    resisting the staying in bed or whatever
  • 00:03:03
    it happens to be but that itself can
  • 00:03:07
    start to evoke dopamine release now I'm
  • 00:03:10
    not David goggin obviously I never will
  • 00:03:12
    be but the way he describes his process
  • 00:03:15
    is a little bit different I think than
  • 00:03:17
    um than just pure like oh I feel great
  • 00:03:20
    doing it he talks a lot of times about
  • 00:03:22
    how it's very very challenging for him
  • 00:03:24
    but when you talk to people who are very
  • 00:03:26
    good at overriding lyic friction you
  • 00:03:28
    start to get the sense that even if it's
  • 00:03:30
    very challenging for them to do that
  • 00:03:32
    they understand the great reward that's
  • 00:03:34
    going to come that's going to come later
  • 00:03:37
    and I think for a lot of people the
  • 00:03:38
    challenge is they don't they haven't
  • 00:03:40
    experienced or they can't see the win
  • 00:03:42
    and and experience the win and so it's
  • 00:03:44
    very hard for them to override limic
  • 00:03:46
    friction and I'm not talking about limic
  • 00:03:47
    friction as this mild little thing limic
  • 00:03:49
    friction is a is a it's like a booming
  • 00:03:53
    voice throughout your brain and body of
  • 00:03:55
    stay in bed sleep is important I heard
  • 00:03:57
    on the podcast sleep is important stay
  • 00:03:59
    in bed and to override that requires an
  • 00:04:01
    immense amount of what we call willpower
  • 00:04:03
    but willpower is top- down
  • 00:04:07
    control it kind of is also going against
  • 00:04:11
    what was required of us as a species
  • 00:04:14
    like instant gratification in many ways
  • 00:04:16
    is a survival mechanism right yeah I
  • 00:04:19
    mean if you could get all your
  • 00:04:20
    sustenance without having to venture out
  • 00:04:22
    too far why would you go any further now
  • 00:04:24
    the evolution the forward evolution of
  • 00:04:26
    culture in our species and individuals
  • 00:04:29
    has been created created by people that
  • 00:04:30
    were willing to push out further and
  • 00:04:32
    further I mean right now we talk a lot
  • 00:04:34
    about Elon right he's the one that's
  • 00:04:36
    sort of like well why limit yourself to
  • 00:04:38
    Earth you know which is a cool concept
  • 00:04:40
    um but this exists in every domain as
  • 00:04:43
    you know uh Rich rol are good friend you
  • 00:04:46
    know anytime we overcome uh doubt
  • 00:04:50
    challenge uh internal doubt and
  • 00:04:52
    challenge we're engaging these
  • 00:04:54
    mechanisms it's a vital part of our
  • 00:04:58
    individual development would you say
  • 00:04:59
    it's a skill absolutely it's a skill and
  • 00:05:02
    there's neuroplasticity in this circuit
  • 00:05:04
    that's the thing that's often not
  • 00:05:06
    discussed is that the ability to focus
  • 00:05:08
    is enhanced by forcing yourself to focus
  • 00:05:11
    the ability to sleep is enhanced by
  • 00:05:14
    getting better at relaxing turning off
  • 00:05:16
    thoughts and the ability to override
  • 00:05:18
    lyic friction can only be created one of
  • 00:05:22
    two ways one is to increase your overall
  • 00:05:23
    levels of alertness through dopamine and
  • 00:05:25
    orrine that's why people take adderal
  • 00:05:27
    and rlin drink caffeine smoke nicotine
  • 00:05:29
    in order to get more alert they're
  • 00:05:31
    trying they're biologically hacking
  • 00:05:33
    their way into the system I think it's
  • 00:05:35
    beautiful when people can
  • 00:05:37
    psychologically I would say I was
  • 00:05:39
    imagine scruffing myself you know like
  • 00:05:41
    you'd Scruff an animal or you SC Scruff
  • 00:05:43
    you scruffing myself and forcing myself
  • 00:05:46
    into it because for me it helps to third
  • 00:05:48
    person myself to it's very hard as the
  • 00:05:51
    as the you know the way the brain is and
  • 00:05:52
    the way we identify as individuals I'm
  • 00:05:54
    not going to um refer to myself in the
  • 00:05:56
    third person um I will not do that
  • 00:05:59
    there's there's a name for that in
  • 00:06:00
    Psychology uh I won't mention it in
  • 00:06:02
    clinical Psychiatry um we we we had a
  • 00:06:05
    bit of a joke before it starts with an N
  • 00:06:07
    yeah um um starts with an n and ends
  • 00:06:10
    with an M um or yeah or anyway
  • 00:06:13
    narcissists generally talk about
  • 00:06:14
    themselves in the third person it's
  • 00:06:16
    hilarious right because they they think
  • 00:06:17
    so much of themselves that they talk
  • 00:06:19
    about themselves in the third person uh
  • 00:06:20
    revealing the the um micro squishy inner
  • 00:06:23
    ego uh of the narcissist but but what
  • 00:06:26
    I'm talking about is third personing
  • 00:06:27
    oneself in service to uh to overriding
  • 00:06:30
    lyic friction and sometimes we we have
  • 00:06:34
    this narrative that's so closely tied to
  • 00:06:36
    our immediate state that we have a hard
  • 00:06:40
    time forcing ourselves into some other
  • 00:06:42
    mode of action and so it can be very
  • 00:06:44
    helpful to take on a view of yourself
  • 00:06:46
    that's living in anticipation of the
  • 00:06:48
    future state that you're going to be in
  • 00:06:50
    like successfully getting out of bed in
  • 00:06:52
    the morning I did this this morning um
  • 00:06:54
    we just I last night I said let's um my
  • 00:06:57
    partner I said let let's go jump in the
  • 00:06:59
    ocean tomorrow morning we got up and it
  • 00:07:00
    was raining it kind of like the smallest
  • 00:07:02
    matter very Misty and I was like oh God
  • 00:07:04
    it's going to be cold and then we're
  • 00:07:05
    driving down there and I didn't tell her
  • 00:07:06
    cuz I I didn't I didn't want her to know
  • 00:07:08
    what I was thinking I hate K in the
  • 00:07:10
    ocean when it's cold I absolutely hate
  • 00:07:11
    it but then we got there and actually
  • 00:07:12
    the water was just a little bit warmer
  • 00:07:14
    than the external environment it was
  • 00:07:15
    beautiful we had the best the best ocean
  • 00:07:17
    dip in the morning and then a saw
  • 00:07:19
    afterwards and it was it was wonderful
  • 00:07:21
    I've been feeling great all day as a
  • 00:07:22
    consequence but you know it took a
  • 00:07:24
    little bit of override that's a mild
  • 00:07:26
    recreational example but I think that
  • 00:07:30
    if we can start to see these reward
  • 00:07:33
    systems and top down control as things
  • 00:07:34
    that we can modulate in real time you
  • 00:07:36
    and use it sparingly I'm not suggesting
  • 00:07:38
    people do this for everything right it
  • 00:07:40
    could be very exhausting to Scruff
  • 00:07:42
    yourself into the best action all the
  • 00:07:44
    time but look I mean people are
  • 00:07:46
    recovering from addiction they they have
  • 00:07:48
    to do this it's a it's a process from
  • 00:07:50
    morning till night how important is is
  • 00:07:53
    tying that to sort of bed down these
  • 00:07:56
    neural systems this rewiring you're
  • 00:07:58
    talking about
  • 00:08:00
    uh how important is tying that to some
  • 00:08:03
    sense of satisfaction or celebrating you
  • 00:08:06
    know you mentioned sort of achievement
  • 00:08:07
    earlier yeah is that sort of critical to
  • 00:08:10
    closing the loop on all that so it's
  • 00:08:12
    very important to experience a win at
  • 00:08:16
    some point but one thing that a lot of
  • 00:08:18
    people um misperceive is that we should
  • 00:08:21
    always celebrate our wins the dopamine
  • 00:08:24
    system is very good at predicting wins
  • 00:08:28
    and when it predict a win if those wins
  • 00:08:31
    come on a regular basis you start
  • 00:08:33
    reducing the amount of dopamine that's
  • 00:08:34
    released in response to those
  • 00:08:39
    winds seems a little counterintuitive
  • 00:08:41
    but the casino owners understand this
  • 00:08:44
    the pattern of reinforcement that works
  • 00:08:46
    best in animals and humans is
  • 00:08:48
    intermittent random reinforcement so one
  • 00:08:51
    thing that you can do and I suggest to
  • 00:08:54
    people is that if you are working hard
  • 00:08:56
    at something or you're really pushing
  • 00:08:57
    yourself sometimes reward yourself but
  • 00:09:00
    occasionally delete the reward because
  • 00:09:02
    it sets up there's a something called
  • 00:09:04
    dopamine reward prediction error again
  • 00:09:06
    we probably don't have time to get into
  • 00:09:07
    all the it's it's a
  • 00:09:10
    computational uh analysis of what keeps
  • 00:09:14
    things uh people and animals motivated
  • 00:09:16
    to continue to pursue and random re uh
  • 00:09:19
    intermittent reinforcement is the
  • 00:09:21
    optimal schedule have you done an
  • 00:09:22
    episode on that uh somewhat I did an
  • 00:09:24
    episode on dopamine sort of a dopamine
  • 00:09:26
    master class we got into it but I
  • 00:09:28
    haven't really boiled it down to a
  • 00:09:29
    specific protocol but it would look
  • 00:09:30
    something like this you're in your
  • 00:09:32
    90-minute learning bout or work bout of
  • 00:09:34
    any kind you're doing your little Gap
  • 00:09:36
    learning things and every once in a
  • 00:09:37
    while you look at the clock you go W
  • 00:09:39
    I've made it 30 minutes without looking
  • 00:09:41
    at my phone you think okay that feels
  • 00:09:43
    pretty good other times um you might uh
  • 00:09:47
    say you know okay I made it to the 45
  • 00:09:49
    minute Mark I'm going to go get myself a
  • 00:09:50
    nice cup of coffee so you have a little
  • 00:09:52
    bit of coffee other times you delete the
  • 00:09:53
    coffee and you keep working what you're
  • 00:09:56
    doing is you're effectively taking that
  • 00:09:57
    goal line and you're moving you're catch
  • 00:09:59
    little micro winds it's sort of like a
  • 00:10:00
    video game where you pick up little
  • 00:10:02
    coins I'm an old school guy I don't play
  • 00:10:04
    video games but the ones I did play like
  • 00:10:05
    you pick up coins you give you power
  • 00:10:07
    like Pac-Man or those like the Super
  • 00:10:09
    Mario Brothers I'm I'm truly old and and
  • 00:10:11
    out of it in respect to this so forgive
  • 00:10:13
    me but what you're doing is you're
  • 00:10:15
    picking up additional lives or points
  • 00:10:18
    but occasionally you don't take anything
  • 00:10:19
    it keeps you in Pursuit keep it guessing
  • 00:10:21
    keep it guessing let's say another way
  • 00:10:23
    to do this is I I suggest people avoid
  • 00:10:26
    layering dopamine you know you have one
  • 00:10:28
    dopamine system that fortunately can be
  • 00:10:31
    activated by a lot of different things
  • 00:10:33
    so for instance I love the feeling of
  • 00:10:35
    being completely rested going into the
  • 00:10:37
    gym we going for a run midm morning
  • 00:10:40
    after a cup of coffee hydrating well
  • 00:10:42
    using the bathroom listening to my
  • 00:10:43
    favorite music on a sunny day but that's
  • 00:10:45
    a lot of things layering in for dopamine
  • 00:10:47
    and what happens is that if that becomes
  • 00:10:50
    your hope and expectation fine but if
  • 00:10:52
    that becomes your requirement for
  • 00:10:54
    actually having a great run or workout
  • 00:10:57
    you're in trouble because the next time
  • 00:11:00
    you're it's not going to be that
  • 00:11:01
    exciting and you're not going to be that
  • 00:11:03
    motivated you actually won't perform as
  • 00:11:04
    well so this year what I've been doing
  • 00:11:06
    is every third or fourth workout or so I
  • 00:11:09
    kind of randomly I leave my phone in the
  • 00:11:11
    car I don't use any music and I don't
  • 00:11:14
    allow myself any kind of pre-workout
  • 00:11:16
    stimulant so I have to generate all the
  • 00:11:18
    force and energy and everything I'm
  • 00:11:19
    going to do from internal processes and
  • 00:11:22
    you might say well that's kind of
  • 00:11:23
    massoch histic why would you do that
  • 00:11:24
    it's supposed to be fun well I'll tell
  • 00:11:25
    you when the next time when you bring
  • 00:11:26
    your headphones and you're listening to
  • 00:11:27
    music you feel like a god in there what
  • 00:11:30
    the re why because you are secreting so
  • 00:11:33
    much more dopamine so much more
  • 00:11:35
    noradrenaline so much more effective at
  • 00:11:37
    performance but then the next time you
  • 00:11:39
    have to throttle it back and so I'm
  • 00:11:41
    excited by all the tools that are out
  • 00:11:42
    there all the you know there's all this
  • 00:11:45
    like cognitive enhancement stuff and
  • 00:11:47
    people are you know plugging into every
  • 00:11:49
    device and they're trying to figure out
  • 00:11:50
    do I have white noise in the background
  • 00:11:51
    or metronomes and all that stuff but
  • 00:11:54
    it's good to not layer in too many
  • 00:11:56
    things um there are other examples of
  • 00:11:59
    this where um are a little more um
  • 00:12:03
    unfortunate uh pornography is a really
  • 00:12:05
    good example there's a huge issue now
  • 00:12:07
    right because pornography is so much
  • 00:12:08
    more readily available on the internet
  • 00:12:10
    now let's just remove the kind of um the
  • 00:12:13
    moral uh judgments about it right
  • 00:12:15
    because that's not what this is about a
  • 00:12:16
    scientific discussion about this would
  • 00:12:17
    say that there's an enormous
  • 00:12:19
    availability and range of imagery that's
  • 00:12:24
    very powerful that feeds directly into
  • 00:12:26
    the dopamine system and a lot of people
  • 00:12:29
    young people who are growing up watching
  • 00:12:31
    a lot of intense pornography are
  • 00:12:32
    suffering from a lot of sexual side
  • 00:12:34
    effects and struggles with sexual
  • 00:12:36
    interactions in real life because those
  • 00:12:39
    interactions are not as intense as the
  • 00:12:40
    things that they're seeing the other
  • 00:12:42
    thing that's happening should just
  • 00:12:43
    mention is that I've got colleagues that
  • 00:12:45
    work on this in Psychiatry that that
  • 00:12:47
    they are wiring their nervous systems to
  • 00:12:49
    become aroused viewing other people
  • 00:12:52
    having sex as opposed to them having it
  • 00:12:54
    and so they're running into a lot of
  • 00:12:56
    trouble there so you what what's
  • 00:12:58
    happening inter the dopamine levels are
  • 00:13:00
    so high that real life cir it's like
  • 00:13:02
    it's like eating extremely palatable
  • 00:13:05
    foods that are just blitzing your system
  • 00:13:07
    every taste bud high salt high sugar
  • 00:13:10
    high fat to the point where it's just
  • 00:13:12
    and let's assume delicious I don't
  • 00:13:13
    generally like those kinds of foods but
  • 00:13:15
    and then all of a sudden it's like
  • 00:13:16
    here's a bowl of rice or a or a salad
  • 00:13:19
    it's going to taste like garbage to you
  • 00:13:20
    because you're first
  • 00:13:26
    anyway poor night sleep is will almost
  • 00:13:29
    always create brain fog if not the first
  • 00:13:31
    day then the second day um brain fog
  • 00:13:34
    could be any number of things it could
  • 00:13:36
    be lack of adrenalin you know some
  • 00:13:37
    people are just not engaged enough in
  • 00:13:39
    what they're doing it is amazing how we
  • 00:13:41
    can be so excited and engaged in certain
  • 00:13:43
    things and not in others and feel so
  • 00:13:46
    sleepy in certain environments and then
  • 00:13:47
    all of a sudden we're wide awake um I've
  • 00:13:49
    lectured to many students that feel this
  • 00:13:51
    way about my material I know the feeling
  • 00:13:53
    there's this there's this I won't go
  • 00:13:54
    into the details but there's this this
  • 00:13:56
    uh uh office in Sydney and whenever I
  • 00:13:59
    walk into this place I I literally feel
  • 00:14:02
    so tired and it might just be the types
  • 00:14:05
    of conversations that I'm usually having
  • 00:14:07
    in this setting and and I'm not fully
  • 00:14:08
    engaged but something triggers me in
  • 00:14:11
    that environment where I just feel
  • 00:14:12
    sleepy well low low oxygen turnover it
  • 00:14:15
    will definitely contribute uh slightly
  • 00:14:18
    elevated temperature low oxygen turnover
  • 00:14:20
    these kinds of things I mean this is the
  • 00:14:21
    post lunch lecture phenomenon I I Don't
  • 00:14:24
    lecture undergraduates anymore but used
  • 00:14:26
    to look out and I would teach at night I
  • 00:14:28
    actually preferred to teach at night
  • 00:14:29
    when I was teaching undergraduates cuz
  • 00:14:30
    it in the evening people are a little
  • 00:14:32
    bit more um conversational so I do these
  • 00:14:34
    nighttime lectures uh 6:00 to 7:30 p.m
  • 00:14:37
    and it was great but there were always a
  • 00:14:38
    couple people just dozing um and I was a
  • 00:14:41
    student that had a hard time staying
  • 00:14:42
    awake in class I think being stationary
  • 00:14:45
    just listening to the hum of a voice you
  • 00:14:47
    know the temperature's up a little bit
  • 00:14:48
    and next thing I know it's like glasses
  • 00:14:50
    over some of the best sleep I ever got
  • 00:14:52
    was in classes but please don't sleep in
  • 00:14:53
    classes if you can't um can avoid it I
  • 00:14:56
    think that that uh being being actively
  • 00:14:59
    engaged in material is very key uh you
  • 00:15:02
    know that I did an episode on ADHD and
  • 00:15:05
    one of the things I learned in
  • 00:15:06
    researching that episode is that people
  • 00:15:07
    who have ADH actually have a a
  • 00:15:09
    remarkable ability to focus if they
  • 00:15:12
    really like the activity which tells you
  • 00:15:15
    that the dopamine system which is
  • 00:15:16
    associated with really liking and
  • 00:15:18
    pursuing something is really key for
  • 00:15:21
    attention and no surprise riddle in and
  • 00:15:24
    ater all mainly work to increase
  • 00:15:27
    attention and focus byre ining dopamine
  • 00:15:29
    and adrenaline so you know I think if we
  • 00:15:32
    like a place and we like a topic and we
  • 00:15:35
    and we care about it we tend to be alert
  • 00:15:38
    for it and when we're not we just kind
  • 00:15:39
    of drift off which is sort of a of
  • 00:15:42
    course answer yeah right like it's
  • 00:15:43
    common sense but it sounds like the the
  • 00:15:46
    the the most important part of hacking
  • 00:15:48
    focus and attention is finding something
  • 00:15:51
    that you enjoy doing that's right and I
  • 00:15:53
    would say find something that you really
  • 00:15:55
    enjoy doing and have a tool so that when
  • 00:15:58
    you have to engage in things that you
  • 00:15:59
    don't want to do you know how to go
  • 00:16:01
    forward Center of mass anyway because
  • 00:16:04
    I'm not saying that people should pursue
  • 00:16:06
    things in life they hate but one thing
  • 00:16:07
    that I did when I was in school for
  • 00:16:09
    instance there were a couple subjects
  • 00:16:10
    that I really didn't like and I would
  • 00:16:12
    try and lie to myself and tell myself
  • 00:16:13
    that I liked it but then I decided Well
  • 00:16:16
    okay adrenaline and dopamine um are
  • 00:16:19
    these alertness molecules and I'm just
  • 00:16:20
    going to think about how much I hate
  • 00:16:22
    this topic and then I'm like I actively
  • 00:16:24
    hate this not bored by it but how much I
  • 00:16:26
    actively hate this topic then all of a
  • 00:16:27
    sudden you get this attentional
  • 00:16:28
    engagement agement I was like you know
  • 00:16:29
    I'm going to defeat this topic just to
  • 00:16:32
    prove like I'm going to wrestle this
  • 00:16:33
    topic to the ground and so then I was
  • 00:16:35
    able to do it cuz I had to take the
  • 00:16:36
    course and then what you find which is
  • 00:16:38
    kind of ironic is then if you do well
  • 00:16:40
    enough on a particular subject you're
  • 00:16:42
    like I kind of like that topic you know
  • 00:16:43
    it's you because you've conquered
  • 00:16:45
    something so I think it's good to be to
  • 00:16:47
    engage in things and find things that
  • 00:16:49
    you really enjoy leverage these dopamine
  • 00:16:52
    systems but look there Comes A Time in
  • 00:16:54
    place where you have to lean into effort
  • 00:16:56
    that you simply did not choose and
  • 00:16:59
    that's that's part of becoming a
  • 00:17:00
    functional adult I think um and it's
  • 00:17:03
    also something that Anna lmy when she
  • 00:17:05
    came on my podcast discussed you know a
  • 00:17:06
    lot of younger people these days are
  • 00:17:09
    really focused on finding their passion
  • 00:17:10
    and they're waiting for something that
  • 00:17:11
    engages them so completely that
  • 00:17:13
    everything seems very fasile and they're
  • 00:17:15
    just able to be forward Center of mass
  • 00:17:17
    all the time sometimes you have to enter
  • 00:17:19
    things through the back door and in
  • 00:17:22
    order to feel really excited about
  • 00:17:23
    something you have to feel as if you
  • 00:17:25
    worked through that friction that's an
  • 00:17:27
    accomplishment in and of itself
  • 00:17:32
    if you're on social media and you're
  • 00:17:33
    scrolling and you don't even know why
  • 00:17:35
    you're scrolling like you don't even
  • 00:17:36
    know what you're looking for your
  • 00:17:38
    dopamine system has been tapped out and
  • 00:17:41
    you need to take a break from it maybe a
  • 00:17:43
    couple hours maybe a couple of days I
  • 00:17:45
    think social media is great I teach
  • 00:17:46
    science on social media I see you all
  • 00:17:48
    the time on social media you know
  • 00:17:49
    there's a lot of great social
  • 00:17:50
    interaction there's a lot of opportunity
  • 00:17:52
    to learn and see things some are funny
  • 00:17:53
    some are interesting some are disturbing
  • 00:17:56
    but when you're at the point where
  • 00:17:57
    you're engaging in something and you
  • 00:17:59
    don't even know what the win is but you
  • 00:18:00
    find yourself reflexively engaging in it
  • 00:18:03
    your dopamine system is now plummeting
  • 00:18:06
    and that's a serious issue so the other
  • 00:18:07
    thing is that a picture is worth a th000
  • 00:18:09
    words and a movie is worth a th000
  • 00:18:12
    pictures our our visual system is so
  • 00:18:14
    tuned to watch motion and to see movies
  • 00:18:18
    so you're seeing movie after movie after
  • 00:18:20
    movie after movie what's happening is
  • 00:18:22
    the context is switching constantly our
  • 00:18:24
    the human brain has never been
  • 00:18:25
    confronted with context switching at
  • 00:18:27
    this rate you know television you know
  • 00:18:30
    went from you know six channels to 12 to
  • 00:18:33
    200 but this is the first time that you
  • 00:18:35
    can walk around with your television you
  • 00:18:37
    can have it in your car you can have it
  • 00:18:38
    on the phone uh excuse me on the plane
  • 00:18:41
    so I use social media and the internet a
  • 00:18:43
    lot um unlike email or reading an
  • 00:18:46
    article online social media is you know
  • 00:18:48
    you can scroll through a thousand
  • 00:18:50
    different or a 100 different contexts
  • 00:18:52
    within 5 minutes and that's a big
  • 00:18:55
    override for the brain and then the rest
  • 00:18:57
    of the world seems kind of boring
  • 00:18:59
    like you know you see people at dinner
  • 00:19:00
    scrolling their phone it's because
  • 00:19:02
    actually the brain wants novelty it's
  • 00:19:05
    seeking novelty all the time these days
  • 00:19:06
    I'm I'm turning off my phone in the
  • 00:19:08
    evenings I'm sort of I'm on there a
  • 00:19:10
    little bit but I'm finding I'm kind of
  • 00:19:11
    sick of the phone I think a lot of
  • 00:19:13
    people are kind of hitting this point
  • 00:19:14
    where they're like ah I'll get on social
  • 00:19:16
    media for an hour or two a day but this
  • 00:19:18
    is getting a little pointless yeah but
  • 00:19:20
    you're right it it has its place but
  • 00:19:21
    it's nice to be able to connect how
  • 00:19:23
    you're engaging with it using it and
  • 00:19:25
    your feelings with the science because
  • 00:19:27
    then all of a sudden it's you're in
  • 00:19:29
    control yeah and I use the phone I I try
  • 00:19:32
    and not look at my phone for the first
  • 00:19:34
    hour that I'm up usually I only make it
  • 00:19:36
    about 30 minutes while I go do my my
  • 00:19:38
    walk um I want to download whatever Pro
  • 00:19:41
    you know processing I did in sleep and
  • 00:19:43
    write a few things down the phone isn't
  • 00:19:45
    Sinister it's our overuse of it that's
  • 00:19:47
    Sinister it's like calories aren't bad
  • 00:19:49
    it's over overindulgence in calories is
  • 00:19:51
    bad it's it's not complicated but I
  • 00:19:53
    think that knowing that the the the
  • 00:19:56
    dopamine system is what got you started
  • 00:19:57
    with the phone but the reason you scroll
  • 00:19:59
    is not for more dopamine it's because
  • 00:20:02
    you are you're it's because you're
  • 00:20:03
    seeking that big dopamine Peak you don't
  • 00:20:06
    it's subconscious but that the amount of
  • 00:20:07
    doping that you're getting from any
  • 00:20:08
    individual post is tiny tiny tiny tiny
  • 00:20:11
    and then it's more about just trying to
  • 00:20:13
    get back to Baseline as I say so when
  • 00:20:15
    you at first any activity that's fun you
  • 00:20:17
    get this huge Peak and then a trough
  • 00:20:19
    then it comes back to Baseline but if
  • 00:20:21
    you engage in the activity too often the
  • 00:20:23
    way that the dopamine system is arranged
  • 00:20:25
    is eventually you're just engaging in
  • 00:20:27
    that activity to just okay you're just
  • 00:20:30
    fighting for normal fighting for neutral
  • 00:20:32
    as I as I call it and that's that's
  • 00:20:34
    addiction that's compulsive use of
  • 00:20:37
    something in order to just feel okay
  • 00:20:39
    that's not
  • 00:20:51
    [Music]
  • 00:20:55
    pleasure the most important thing to
  • 00:20:57
    understand is that for most adults so
  • 00:21:00
    that is people about age 18 to 20 and
  • 00:21:03
    older daily caffeine consumption is not
  • 00:21:06
    going to be a problem provided it does
  • 00:21:09
    not induce anxiety and certainly
  • 00:21:12
    provided that not induce anxiety or
  • 00:21:14
    panic attacks and provided that it does
  • 00:21:16
    not disrupt your nighttime sleep this is
  • 00:21:20
    why I always recommend that if you are
  • 00:21:22
    going to consume caffeine in any form
  • 00:21:24
    coffee tea soda or otherwise that you
  • 00:21:27
    try not to ingest caffeine within the 8
  • 00:21:30
    and ideally within the 10 or even 12
  • 00:21:33
    hours prior to bedtime that's because
  • 00:21:35
    the halflife of caffeine is such that
  • 00:21:37
    even if you are able to for instance
  • 00:21:39
    have a cup of coffee around 3:00 p.m. or
  • 00:21:41
    400 p.m. and then fall asleep around
  • 00:21:44
    midnight the architecture of the sleep
  • 00:21:47
    that you get is going to be disrupted
  • 00:21:49
    for instance it is very important that
  • 00:21:52
    you get sufficient amounts of both slow
  • 00:21:54
    wave deep sleep as well as rapid eye
  • 00:21:56
    movement sleep each night and if you can
  • 00:21:58
    consume caffeine too close to bedtime
  • 00:22:00
    and here I'm defining too close as
  • 00:22:02
    anywhere from 8 to 12 hours before going
  • 00:22:04
    to sleep chances are you're not going to
  • 00:22:06
    get as much rapid eye movement sleep or
  • 00:22:09
    slow wave sleep that you would otherwise
  • 00:22:12
    and it is the amount of rapid eye
  • 00:22:14
    movement sleep and slow wave sleep that
  • 00:22:16
    together lead to whether or not you feel
  • 00:22:18
    you had a good night sleep in terms of
  • 00:22:20
    your next day alertness and cognitive
  • 00:22:23
    abilities now again some people may find
  • 00:22:25
    that they can drink caffeine in the late
  • 00:22:26
    afternoon maybe even at night and still
  • 00:22:28
    fall asleep but I promise you even if
  • 00:22:30
    you're in that category you will sleep
  • 00:22:32
    far better meaning the architecture of
  • 00:22:35
    your sleep will be better and you will
  • 00:22:36
    feel far more rested the next day if you
  • 00:22:39
    abstain from caffeine within the 8 to 12
  • 00:22:41
    hours prior to bedtime and I should also
  • 00:22:44
    say that none of us are perfect myself
  • 00:22:46
    included I will sometimes have a cup of
  • 00:22:48
    coffee in the late afternoon and
  • 00:22:51
    sometimes that will cause me to stay up
  • 00:22:52
    a little bit later sometimes it won't I
  • 00:22:54
    don't think you want to obsess or worry
  • 00:22:56
    too much about having some caffeine
  • 00:22:57
    every once a while in the late afternoon
  • 00:23:00
    if you are still able to fall asleep but
  • 00:23:01
    don't make it a regular habit now as far
  • 00:23:04
    as we know there is no drawback to
  • 00:23:07
    consuming caffeine on a daily basis
  • 00:23:09
    again provided it does not disrupt your
  • 00:23:10
    nighttime sleep and provided that it
  • 00:23:12
    does not induce anxiety in fact most of
  • 00:23:16
    the world consumes caffeine every single
  • 00:23:18
    day the current estimates are that 90%
  • 00:23:21
    that's right 90 90% of adults throughout
  • 00:23:26
    the world consume a caffeinated beverage
  • 00:23:28
    every every single day that's a
  • 00:23:30
    staggeringly high number making caffeine
  • 00:23:32
    the most popular drug on the planet in
  • 00:23:35
    fact because of the way that caffeine
  • 00:23:37
    works and just to remind you how it
  • 00:23:39
    works it effectively blocks adenosine
  • 00:23:42
    receptors adenosine is a molecule that
  • 00:23:43
    builds up in your brain and body more
  • 00:23:46
    and more according to how long you've
  • 00:23:48
    been awake it makes you feel sleepy
  • 00:23:50
    caffeine blocks the adenosine receptor
  • 00:23:52
    and then when it is dislodged from that
  • 00:23:55
    receptor whatever adenosine has built up
  • 00:23:57
    and is around can then bind to the
  • 00:24:00
    adenosine receptor and makes you feel
  • 00:24:02
    very sleepy that's the caffeine crash so
  • 00:24:04
    if 90% of the adult population of the
  • 00:24:06
    planet Earth is consuming caffeine every
  • 00:24:08
    day that means 90% of the adult
  • 00:24:10
    population of planet Earth is blocking
  • 00:24:13
    their adenosine receptors for some
  • 00:24:15
    portion of their daily life and then
  • 00:24:17
    their adenosine is binding to the vacant
  • 00:24:20
    receptor once the caffeine has dislodged
  • 00:24:23
    and why are 90% of adult humans
  • 00:24:26
    consuming caffeine every day well to
  • 00:24:28
    feel more energized more focused to have
  • 00:24:31
    more both cognitive energy and physical
  • 00:24:35
    energy now of course most people are not
  • 00:24:37
    walking around thinking oh caffeine
  • 00:24:39
    gives me more energy more Focus Etc most
  • 00:24:42
    people are consuming caffeine every
  • 00:24:44
    single day and are consuming caffeine
  • 00:24:46
    every single day in order to feel quote
  • 00:24:48
    unquote normal to be at their Baseline
  • 00:24:51
    level of cognitive ability and physical
  • 00:24:54
    energy and so
  • 00:24:56
    on in fact if you look at the data on
  • 00:24:59
    caffeine consumption what you'll find is
  • 00:25:01
    that caffeine actually is a cognitive
  • 00:25:04
    enhancer it can improve learning in
  • 00:25:05
    memory it can increase physical energy
  • 00:25:07
    it can increase mental and physical
  • 00:25:09
    stamina but a feature of those studies
  • 00:25:12
    that's not often discussed but that was
  • 00:25:15
    however discussed in the full episode on
  • 00:25:17
    caffeine is that studies of caffeine
  • 00:25:19
    typically are done by taking chronic
  • 00:25:21
    caffeine users and then having them
  • 00:25:23
    abstain from caffeine for some period of
  • 00:25:26
    time usually 4 days to two weeks in
  • 00:25:29
    which time they undergo caffeine
  • 00:25:31
    withdrawal they do not feel well they
  • 00:25:33
    get foggy headed they have less energy
  • 00:25:36
    there's some malays sometimes even some
  • 00:25:38
    mild
  • 00:25:39
    depression and then what they do is they
  • 00:25:41
    have people take caffeine and take a
  • 00:25:44
    cognitive exam or do some physical
  • 00:25:46
    activity and compare their performance
  • 00:25:48
    to what it was when they were in the
  • 00:25:49
    withdrawal State another typical form of
  • 00:25:52
    study on caffeine is to take people who
  • 00:25:54
    are naive to caffeine or who never take
  • 00:25:57
    caffeine and then have them ingest
  • 00:25:58
    caffeine and then measure their
  • 00:26:00
    cognitive Andor physical performance and
  • 00:26:01
    in both cases you see improvements what
  • 00:26:03
    I'm saying here is that daily caffeine
  • 00:26:06
    consumption is not going to lead to
  • 00:26:08
    improvements in cognitive ability or
  • 00:26:12
    improvements in physical ability above
  • 00:26:14
    one's Baseline unless you either abstain
  • 00:26:17
    from caffeine for some period of time
  • 00:26:18
    typically 4 days to 2 weeks prior or you
  • 00:26:21
    are not somebody who typically ingests
  • 00:26:24
    caffeine in other words 90% of the
  • 00:26:26
    world's population is drinking caffeine
  • 00:26:28
    on a daily basis to be at their normal
  • 00:26:31
    level of mental and physical
  • 00:26:34
    functioning and I would say that if you
  • 00:26:36
    are going to drink your caffeine drink
  • 00:26:38
    it in the early part of the day as I
  • 00:26:40
    mentioned earlier I am a big proponent
  • 00:26:42
    of delaying your first caffeine intake
  • 00:26:44
    until at least 90 minutes after waking
  • 00:26:46
    in order to avoid the afternoon crash
  • 00:26:47
    I've talked a lot about this on the
  • 00:26:49
    podcast there are a lot of Clips on the
  • 00:26:50
    internet explaining the rationale behind
  • 00:26:52
    that and if you do experience an
  • 00:26:53
    afternoon crash in energy I do recommend
  • 00:26:56
    delaying your morning caffeine intake to
  • 00:26:58
    to 90 to 120 minutes after waking now
  • 00:27:01
    for people that want to get more of a
  • 00:27:03
    true cognitive enhancing and
  • 00:27:05
    performance-enhancing effect from
  • 00:27:07
    caffeine again you're going to have to
  • 00:27:08
    abstain from caffeine for about 4 days
  • 00:27:12
    regular caffeine drinkers that's going
  • 00:27:13
    to be difficult right that is going to
  • 00:27:16
    lead to headaches that's going to lead
  • 00:27:18
    to brain fog that's going to lead to
  • 00:27:20
    feelings of malaise in fact the last
  • 00:27:22
    time I took 4 days off or even a week
  • 00:27:25
    off from caffeine consumption was when I
  • 00:27:27
    was sick I don't get sick very often but
  • 00:27:29
    when I am sick I generally abstain from
  • 00:27:31
    caffeine and sometimes I wonder whether
  • 00:27:32
    or not the malaise I feel from whatever
  • 00:27:35
    um you know viral or bacterial thing I
  • 00:27:37
    might be dealing with when I'm sick is
  • 00:27:39
    in part the malaise of caffeine
  • 00:27:40
    withdrawal I certainly notice I feel
  • 00:27:42
    much better when I return to drinking
  • 00:27:44
    caffine but that tends to coincide with
  • 00:27:45
    feeling relief from whatever sinus
  • 00:27:47
    symptoms and other symptoms I might have
  • 00:27:49
    been experiencing from the illness so
  • 00:27:50
    it's not a good experiment I can't tease
  • 00:27:52
    apart those variables so the short
  • 00:27:54
    answer is for most adults there does not
  • 00:27:55
    seem to be any major downside to
  • 00:27:57
    consuming caffeine and there have been
  • 00:27:59
    scattered reports here and there in
  • 00:28:01
    humans showing that ingesting caffeine
  • 00:28:04
    can increase dopamine receptors which
  • 00:28:07
    will effectively allow you to get more
  • 00:28:10
    out of the dopamine that you produce uh
  • 00:28:12
    this is why caffeine has an mood
  • 00:28:14
    elevating as well as energy elevating
  • 00:28:16
    effect I should point out that some
  • 00:28:18
    people just cannot tolerate caffeine it
  • 00:28:20
    makes them too jittery too anxious they
  • 00:28:21
    start sweating they get heart
  • 00:28:23
    palpitations it's very hard for these
  • 00:28:25
    people to build up a tolerance to
  • 00:28:26
    caffeine that allows them to enjoy it
  • 00:28:27
    these are the people that can even feel
  • 00:28:30
    a fluttering of the heart and a lot of
  • 00:28:31
    energy lift from decaf coffee you know
  • 00:28:34
    something that you know to me is just a
  • 00:28:36
    foreign concept but some people are just
  • 00:28:38
    that sensitive to caffeine that even the
  • 00:28:41
    small amounts of caffeine in chocolate
  • 00:28:42
    or decaf coffee make them feel too alert
  • 00:28:45
    and they should abstain from caffeine I
  • 00:28:47
    don't think they are in any way harming
  • 00:28:49
    their health by abstaining from
  • 00:28:53
    caffeine now getting back to the
  • 00:28:55
    original question about daily caffeine
  • 00:28:57
    consumption this person goes on to say
  • 00:28:59
    that for them okay this is their
  • 00:29:02
    personal experience after a few weeks of
  • 00:29:04
    consumption of daily caffeine the
  • 00:29:06
    negatives start to outweigh the positive
  • 00:29:08
    ones they're getting poor quality sleep
  • 00:29:09
    lack of appetite anxiety Etc and when
  • 00:29:12
    they don't consume caffeine they find it
  • 00:29:14
    a lot easier to be mindful and their
  • 00:29:15
    meditation practice is much better but
  • 00:29:17
    they're lethargic and less motivated
  • 00:29:19
    okay so what they're describing are all
  • 00:29:20
    the classic symptoms of caffeine overuse
  • 00:29:23
    probably not abuse in this case although
  • 00:29:24
    caffeine can be truly abused people
  • 00:29:26
    taking caffeine pills Etc in large
  • 00:29:29
    quantities we're not talking about that
  • 00:29:31
    but this person is describing the
  • 00:29:33
    classic pattern of overuse of caffeine
  • 00:29:36
    and the classic pattern of withdrawal
  • 00:29:38
    from caffeine when they stop taking it
  • 00:29:40
    so what should somebody like this do and
  • 00:29:42
    I think that's an important question to
  • 00:29:44
    answer because I think a lot of people
  • 00:29:45
    fall into this category they drink
  • 00:29:47
    caffeine every day they're no longer
  • 00:29:49
    getting the performance-enhancing effect
  • 00:29:51
    of caffeine so they're taking it just to
  • 00:29:52
    be normal or feel like they can focus
  • 00:29:55
    normally and have normal amounts of
  • 00:29:56
    energy but then if they try and come off
  • 00:29:58
    off they feel worse okay there are a
  • 00:29:59
    couple ways to do this you can taper
  • 00:30:01
    your caffeine intake off over the course
  • 00:30:03
    of 4 to 7 days but most people don't
  • 00:30:06
    have the discipline or don't want to
  • 00:30:07
    spend the time doing that but if you
  • 00:30:09
    want to the way you would do that is you
  • 00:30:11
    would cut it by about 10 or 15% per day
  • 00:30:14
    you could do that by volume or you could
  • 00:30:15
    do that by concentration of coffee that
  • 00:30:17
    sort of thing a simpler way to go about
  • 00:30:19
    all this that still will allow you to
  • 00:30:21
    get some of the performance-enhancing
  • 00:30:23
    effects of caffeine and yet experience
  • 00:30:25
    far less withdrawal would be two things
  • 00:30:28
    first of all just have your amount of
  • 00:30:31
    caffeine intake for 2 or 3 days so again
  • 00:30:34
    that could be by volume or it could be
  • 00:30:36
    by
  • 00:30:37
    concentration probably easiest to do by
  • 00:30:39
    volume and so instead of drinking an 8 O
  • 00:30:41
    Coffee in the morning maybe you do 4
  • 00:30:42
    ounces of regular coffee 4 ounces of
  • 00:30:45
    Decap or you just have the 4 ounces of
  • 00:30:46
    coffee you do that for 3 or 4 days and
  • 00:30:50
    then you take perhaps one full day off
  • 00:30:53
    from caffeine maybe another full day off
  • 00:30:56
    you're going to feel a lot less
  • 00:30:59
    bad on those two days having cut your
  • 00:31:01
    caffeine intake in half in the previous
  • 00:31:02
    four days than you would if you just
  • 00:31:03
    went cold turkey and then you go back to
  • 00:31:07
    ingesting caffeine but you go back to
  • 00:31:09
    ingesting caffeine at that 50% dose or
  • 00:31:12
    what used to represent that 50% dose of
  • 00:31:14
    caffeine for you and you just continue
  • 00:31:16
    that way on a daily basis and then every
  • 00:31:18
    once in a while when you want the
  • 00:31:19
    performance-enhancing effects of
  • 00:31:20
    caffeine you go back to what was your
  • 00:31:22
    original dose which is now double what
  • 00:31:25
    you're taking on a on a daily basis so
  • 00:31:27
    what we're really talking about here is
  • 00:31:28
    not going cold turkey we're not talking
  • 00:31:30
    about quitting caffeine indefinitely
  • 00:31:32
    what we're talking about is cutting the
  • 00:31:34
    amount of caffeine that you drink in
  • 00:31:36
    half for about 4 days okay plus or minus
  • 00:31:39
    a day and then taking 2 days off from
  • 00:31:42
    caffeine completely and then going back
  • 00:31:45
    on that half dose of caffeine
  • 00:31:47
    indefinitely that's your new Baseline of
  • 00:31:50
    caffeine intake and then every once in a
  • 00:31:52
    while if you need a bit more of a lift
  • 00:31:53
    you ingest twice as much caffeine or a
  • 00:31:55
    coffee that's twice as concentrated we
  • 00:31:57
    should acknowledge that most people
  • 00:31:58
    aren't going to be really precise about
  • 00:32:01
    the amount of ounces and the amount of
  • 00:32:02
    caffeine nonetheless it's pretty
  • 00:32:04
    straightforward to know that you're
  • 00:32:06
    reducing your caffeine intake certainly
  • 00:32:07
    is clear to know if you're ingesting no
  • 00:32:09
    caffeine for a couple of days and it's
  • 00:32:12
    pretty clear when you're doubling the
  • 00:32:13
    amount of caffeine but you don't have to
  • 00:32:14
    worry so much that you're exactly
  • 00:32:16
    doubling the amount of caffeine you
  • 00:32:17
    could drink one and a half times as much
  • 00:32:19
    as you happened to drink on the day
  • 00:32:20
    before or you could drink three times as
  • 00:32:23
    much you would definitely feel it if you
  • 00:32:24
    drink three times as much one very
  • 00:32:26
    important thing to recognize is that on
  • 00:32:28
    any day where you really spike your
  • 00:32:30
    caffeine intake above Baseline no matter
  • 00:32:32
    where that Baseline is when you start
  • 00:32:34
    could be zero could be 400 milligrams
  • 00:32:36
    could be 200 milligrams when you double
  • 00:32:38
    that intake you will get a big boost of
  • 00:32:42
    energy and the next day you're going to
  • 00:32:44
    feel the crash from that you're going to
  • 00:32:46
    feel more lethargic you're going to feel
  • 00:32:47
    not so good this has to do with dopamine
  • 00:32:49
    receptor modulation this has to do with
  • 00:32:51
    a Denine receptor modulation the
  • 00:32:53
    important thing to do is not continue to
  • 00:32:55
    consume that elevated level of caffeine
  • 00:32:56
    which is what most people do do and then
  • 00:32:58
    they set a new higher Baseline just to
  • 00:33:00
    feel normal the key thing is to just
  • 00:33:02
    manage to get through that crash day
  • 00:33:06
    manage to get through that one day where
  • 00:33:07
    you feel a little less good or maybe
  • 00:33:09
    even down a bit get outside a bit get
  • 00:33:11
    some more Sunshine we know that spikes
  • 00:33:12
    your cortisol in a good way right it can
  • 00:33:14
    increase uh the catacol amines dopamine
  • 00:33:17
    Etc get a little bit more sunlight get a
  • 00:33:19
    little bit more movement get outside do
  • 00:33:20
    something to offset those feelings of
  • 00:33:22
    malaise and then get right back to your
  • 00:33:23
    original goal level of caffeine each day
  • 00:33:26
    there's no use in getting so
  • 00:33:28
    quantitative that you make your life
  • 00:33:29
    miserable you know measuring things out
  • 00:33:31
    like a laboratory chemist if you're that
  • 00:33:33
    type and you want to do that be my guest
  • 00:33:35
    but unless you're taking caffeine in
  • 00:33:36
    pill form it's very very hard to get
  • 00:33:39
    extremely exact about the amounts of
  • 00:33:41
    caffeine that you're ingesting so it is
  • 00:33:43
    okay to eyeball it but understand the
  • 00:33:45
    Contour of how caffeine works and what
  • 00:33:47
    the caffeine performance- enhancing
  • 00:33:49
    effect comes from it comes from a
  • 00:33:51
    caffeine intake above Baseline
  • 00:33:52
    understand that anytime you go above
  • 00:33:54
    Baseline with your caffeine intake
  • 00:33:55
    there's the potential of some anxiety
  • 00:33:57
    understand and that there's going to be
  • 00:33:59
    a slight withdrawal effect that lasts
  • 00:34:01
    about 24 to 48 hours battle through that
  • 00:34:04
    short period and you'll be right back
  • 00:34:06
    where you started and where you need to
  • 00:34:08
    be so that you can enjoy caffeine on a
  • 00:34:10
    daily basis and derive the benefits
  • 00:34:12
    because there are many benefits to
  • 00:34:14
    drinking caffeine and avoiding some of
  • 00:34:16
    the potential hazards
  • 00:34:29
    learning is a two-stage process and the
  • 00:34:31
    learning I'm referring to is
  • 00:34:34
    specifically deliberate learning you
  • 00:34:35
    know children are learning passively all
  • 00:34:37
    the time they're taking new information
  • 00:34:38
    their brain is it's not a complete
  • 00:34:40
    tarasa it's not a complete Blank Slate
  • 00:34:42
    there's some hardwired functions they
  • 00:34:44
    show up with thank goodness like
  • 00:34:45
    breathing like heart rate uh heart
  • 00:34:48
    controlling heart rate thats but that
  • 00:34:49
    helps I mean you know offload as much as
  • 00:34:52
    you can to the genetic program to
  • 00:34:54
    hardwire the nervous system so they can
  • 00:34:56
    learn how to walk and walking a good
  • 00:34:58
    example a a a kid learns how to walk and
  • 00:35:01
    then walks reflexively but of course at
  • 00:35:03
    any stage you can think about how you're
  • 00:35:04
    walking you can do Hopscotch and means
  • 00:35:06
    you have to change your Cadence of
  • 00:35:08
    jumping and walking right so that's this
  • 00:35:10
    uh flexible transition between voluntary
  • 00:35:13
    and involuntary movement but you have to
  • 00:35:15
    learn how to walk and so but what we're
  • 00:35:18
    talking about now is generally
  • 00:35:20
    deliberate learning language learning
  • 00:35:21
    skill learning learning knowledge of any
  • 00:35:23
    kind um learning how to you know
  • 00:35:28
    navigate the emotional dynamics of a
  • 00:35:29
    relationship or anything two phases one
  • 00:35:33
    is active engagement and focus uh much
  • 00:35:36
    of the trigger for neuroplasticity as a
  • 00:35:40
    process is engaged by dopamine and
  • 00:35:43
    neurop nephrine and a molecule called
  • 00:35:45
    acetycholine which is liberated from
  • 00:35:46
    multiple sources we always talked about
  • 00:35:48
    how acetylcholine controls the the
  • 00:35:50
    contraction of muscles but in the brain
  • 00:35:52
    acetylcholine is mainly comes from two
  • 00:35:55
    sets of neurons one in the brain stem
  • 00:35:56
    and another in the basil for brain brain
  • 00:35:58
    and it serves as a kind of a highlighter
  • 00:36:01
    marking particular connections or
  • 00:36:03
    neurons that later stand a chance to
  • 00:36:07
    become stronger so let me give an
  • 00:36:08
    example I don't speak a second language
  • 00:36:11
    but let's say I decided I was going to
  • 00:36:12
    learn conversational French I would
  • 00:36:13
    learn some nouns or some verbs I would I
  • 00:36:16
    would focus on this and the greater
  • 00:36:17
    degree of focus that I bring the greater
  • 00:36:19
    amount of acetylcholine is released at
  • 00:36:22
    that time and at the particular
  • 00:36:24
    locations in the brain they're involved
  • 00:36:25
    in enunciating the words and writing the
  • 00:36:27
    comp renson you know multiple spots
  • 00:36:28
    within the brain that kind of marks
  • 00:36:30
    those or Flags those areas as
  • 00:36:33
    potentially changing later but the
  • 00:36:36
    actual rewiring of the nervous system
  • 00:36:38
    happens during states of deep sleep or
  • 00:36:40
    sleep-like states and so it's a so when
  • 00:36:43
    we say neuroplasticity the brain's
  • 00:36:44
    ability to change in response to
  • 00:36:46
    experience that's a two-part process
  • 00:36:48
    it's a process it's not an event we
  • 00:36:49
    always think about things as events but
  • 00:36:51
    em biology almost everything is a
  • 00:36:52
    process so the the takeaway from this is
  • 00:36:55
    in order to learn at any age
  • 00:36:58
    the most critical thing is that you
  • 00:36:59
    bring as much focus and active
  • 00:37:01
    engagement to the learning the the
  • 00:37:04
    encoding of the information bringing in
  • 00:37:05
    the information and then that you get
  • 00:37:07
    into a state of deep rest as quickly as
  • 00:37:10
    possible typically that would be the
  • 00:37:11
    night after you learn uh after you have
  • 00:37:14
    this trigger but there are some
  • 00:37:16
    beautiful studies published in cell
  • 00:37:17
    reports last year and the year before
  • 00:37:19
    showing that people who take a 20-minute
  • 00:37:21
    nap within the 4 hours after these uh
  • 00:37:24
    triggering learning or people that do a
  • 00:37:26
    non-sleep deep breath rest type protocol
  • 00:37:28
    even just sitting there quietly not
  • 00:37:30
    doing anything they learn much faster in
  • 00:37:32
    other words the brain rewires much
  • 00:37:33
    faster is that interesting it's very
  • 00:37:35
    interesting and what's happening is very
  • 00:37:37
    interesting we've long known that during
  • 00:37:39
    sleep there's a replay of the neurons in
  • 00:37:41
    the same sequence that they were played
  • 00:37:44
    during the activity in the uh earlier in
  • 00:37:46
    that day sometimes even backwards for
  • 00:37:47
    some reason it's like the songs played
  • 00:37:49
    backwards and I who knows why I don't
  • 00:37:51
    think we should focus too much on that
  • 00:37:52
    right now but that replay is the
  • 00:37:54
    consolidation of the information you
  • 00:37:56
    learn this is why you try something
  • 00:37:57
    physically try it physically you can't
  • 00:37:59
    do it you can't do it and then you come
  • 00:38:00
    back a week later and voila you can do
  • 00:38:02
    it you had the opportunity to change the
  • 00:38:04
    neural circuits so that now you can do
  • 00:38:06
    it the these non-sleep deep rest or
  • 00:38:09
    these shallow naps of 20 to 30 minutes
  • 00:38:12
    also create a replay or a firing of the
  • 00:38:14
    neurons but there's an additional tool
  • 00:38:16
    so so what sorry I should say there's a
  • 00:38:17
    tool which is get as focused as you can
  • 00:38:20
    but then relax as deeply
  • 00:38:23
    as you know people think that the
  • 00:38:25
    expectation is that you're going to be
  • 00:38:27
    like a beam of focus for 90 minutes
  • 00:38:29
    that's not the case you can flicker in
  • 00:38:30
    and out you're going to get distracted
  • 00:38:32
    you bring yourself back I mean focus is
  • 00:38:34
    an active process of bringing that
  • 00:38:35
    Spotlight of attention back it's always
  • 00:38:37
    much easier without the phone much
  • 00:38:39
    easier without the phone much easier
  • 00:38:40
    using a program called Freedom free
  • 00:38:42
    program online where you can just turn
  • 00:38:44
    off the internet um it's I I'll tell
  • 00:38:48
    it's very painful as you know and yet
  • 00:38:51
    there's something deeply satisfying
  • 00:38:52
    about completing one of these 90-minute
  • 00:38:54
    bouts you really feel good in your brain
  • 00:38:56
    and body because we were actually
  • 00:38:57
    designed to do this um definitely feels
  • 00:39:00
    like a grind at some stage oh yeah and
  • 00:39:02
    that friction and that uh anxiety
  • 00:39:05
    sometimes that we feel is adrenaline
  • 00:39:08
    it's it's supposed to be stressful to
  • 00:39:09
    learn it's this idea that we just sit
  • 00:39:11
    back and learn or that you know movies
  • 00:39:13
    have really destroyed the notion of
  • 00:39:14
    learn the idea that you're going to like
  • 00:39:15
    pick up the sword and suddenly have the
  • 00:39:17
    skills you know forget it it's like this
  • 00:39:20
    doesn't work that way I mean it's
  • 00:39:22
    friction friction friction friction
  • 00:39:23
    friction and some days are good and some
  • 00:39:25
    days are worse if you slept better
  • 00:39:27
    generally it's better people are always
  • 00:39:28
    trying to optimize how much caffeine
  • 00:39:30
    background noise yes noise yes music no
  • 00:39:32
    music you have to tweak things according
  • 00:39:34
    to your circumstances but you n after
  • 00:39:37
    about 90 minutes should really take a
  • 00:39:39
    break and let your mind go idle somewhat
  • 00:39:42
    ideally you would take a 20 minute nap
  • 00:39:43
    or a 30 minute nap or do a non-sleep
  • 00:39:46
    deep breast protocol within the first
  • 00:39:48
    hour to four hours after that but a lot
  • 00:39:51
    of us have a lot of Demands you go
  • 00:39:52
    straight from a 90-minute bout to
  • 00:39:55
    commuting sleep that you get that night
  • 00:39:57
    is going to be the most powerful tool
  • 00:39:59
    for wiring the nervous system right
  • 00:40:01
    that's that's when it really happens so
  • 00:40:03
    we can talk about tools to to get into
  • 00:40:05
    deep sleep and stay asleep uh more if
  • 00:40:07
    you like but there's another thing that
  • 00:40:09
    you can do which is that there's a
  • 00:40:11
    beautiful literature on what's called
  • 00:40:13
    Gap learning effects where let's say uh
  • 00:40:16
    and this has been looked at for physical
  • 00:40:17
    skill learning for music learning math
  • 00:40:19
    Etc where if every couple of minutes
  • 00:40:22
    just randomly during your intense
  • 00:40:25
    learning or Focus you pause and you just
  • 00:40:27
    take 10 seconds and do
  • 00:40:31
    nothing just let your brain idle eyes
  • 00:40:33
    open or eyes closed doesn't matter what
  • 00:40:35
    happens is your rates of learning
  • 00:40:37
    actually increase and the reason is now
  • 00:40:39
    they've done neuroimaging on this really
  • 00:40:41
    excellent studies publishing great
  • 00:40:43
    journals show that during those little
  • 00:40:46
    gaps that you're taking there's a replay
  • 00:40:48
    of the neurons very fast at something
  • 00:40:50
    like 10 or 20x the speed that the
  • 00:40:52
    normally they would be rehearsing it so
  • 00:40:53
    you're getting more repetitions during
  • 00:40:55
    the by by stopping every once in a while
  • 00:40:58
    now you actually have to do the work um
  • 00:41:01
    and how many of these to insert and it
  • 00:41:02
    should be random so there are some free
  • 00:41:05
    apps out there where you can set like a
  • 00:41:06
    random buzzer or just every once in a
  • 00:41:09
    while while you're writing or trying to
  • 00:41:10
    do something you just pause and do
  • 00:41:12
    nothing where was that tool when I was
  • 00:41:14
    going through school yeah exactly and I
  • 00:41:16
    think that the the the science on this
  • 00:41:18
    dates back about 20 years but it's only
  • 00:41:20
    now that there's an enough of what I
  • 00:41:22
    call kind of center of mass around these
  • 00:41:24
    studies that really point to the fact
  • 00:41:25
    that Gap learning effects are really
  • 00:41:27
    strong uh they're very beneficial you
  • 00:41:29
    learn faster so it's Focus rest Focus
  • 00:41:32
    rest Focus rest and that can be done on
  • 00:41:34
    the micro level like within that
  • 00:41:35
    90-minute block let's just make up a
  • 00:41:37
    number for fun so people have something
  • 00:41:38
    to to Anchor to if you're going to sit
  • 00:41:41
    down and do an hour of work let's say
  • 00:41:42
    for every 60 Minutes of focus or
  • 00:41:44
    learning that you try and do introduce
  • 00:41:46
    um 30 30 gaps of 10 seconds at random
  • 00:41:50
    and and truly at random not on a regular
  • 00:41:53
    interval and then sometime later that
  • 00:41:56
    day if you can do an nsdr non-sleep deep
  • 00:41:58
    bre and if you can't okay no big deal
  • 00:42:01
    you won't learn as fast but you'll still
  • 00:42:03
    learn provided that you get into deep
  • 00:42:05
    sleep that night and you let's say you
  • 00:42:07
    have a lousy night's sleep you'll still
  • 00:42:08
    learn but you won't learn as well and
  • 00:42:10
    maybe the next night you stand a chance
  • 00:42:12
    of encoding that information so
  • 00:42:14
    neuroplasticity involves a very strong
  • 00:42:15
    trigger and then deep relaxation is when
  • 00:42:18
    the actual rewiring occurs and there are
  • 00:42:20
    exceptions to this but I should just
  • 00:42:22
    mention because it brings us back to an
  • 00:42:23
    earlier point that when you think about
  • 00:42:26
    the the tools that people use to enhance
  • 00:42:28
    Focus Rin adderal El tyrosine excessive
  • 00:42:31
    amounts of caffeine
  • 00:42:33
    nicotine those all help with the trigger
  • 00:42:36
    part but they don't help with the
  • 00:42:37
    relaxation part and so a lot of people
  • 00:42:40
    don't learn they just get really good at
  • 00:42:43
    doing but they don't actually learn uh
  • 00:42:45
    so very effective people in regardless
  • 00:42:48
    of workplace or activity sport or
  • 00:42:50
    cognitive work or
  • 00:42:52
    otherwise perform very well because
  • 00:42:54
    they're very good at regulating the
  • 00:42:55
    Seesaw of focus
  • 00:42:58
    relax Focus relax and in the long term
  • 00:43:01
    it also is is very health enhancing as
  • 00:43:03
    opposed to health depleting I mean it I
  • 00:43:05
    know a dozen or more people who have
  • 00:43:07
    done very very well in business or
  • 00:43:09
    Academia who are a a mess they I mean
  • 00:43:12
    they they're physically aess they're
  • 00:43:13
    emotionally aess they're mentally aess
  • 00:43:15
    their relationships are a mess people
  • 00:43:17
    that I you know consider successful are
  • 00:43:20
    people that are very successful in
  • 00:43:21
    multiple domains of life and that almost
  • 00:43:24
    always correlates with an ability to
  • 00:43:26
    engage and and disengage deliberately
  • 00:43:28
    engage and and deliberately
  • 00:43:32
    disengage and thank you um Matthew
  • 00:43:35
    Walker and others who have have
  • 00:43:37
    emphasized the importance of sleep you
  • 00:43:38
    know I mean Matthew was really kind of
  • 00:43:41
    first man in on trying to convince the
  • 00:43:42
    world that this whole idea of you'll
  • 00:43:43
    sleep when you're dead is really foolish
  • 00:43:46
    and listen I think it's a it's a fact
  • 00:43:49
    that in order to get good at anything
  • 00:43:51
    unless you're just an absolute Talent
  • 00:43:54
    you need to apply yourself and and work
  • 00:43:56
    hard and sometimes work longer and
  • 00:43:58
    harder than you feel like working or or
  • 00:43:59
    is healthy for yourself and that's
  • 00:44:01
    that's a reality but Matt I think really
  • 00:44:05
    pointed out that sleep is important uh
  • 00:44:07
    for Learning and a number of other
  • 00:44:08
    aspects of Health I think that the the
  • 00:44:12
    ability to toggle back and forth between
  • 00:44:15
    engaged and disengaged States and to see
  • 00:44:17
    that whole process engage and disengage
  • 00:44:20
    in the dynamic control of that and
  • 00:44:22
    deliberate self-control of that that is
  • 00:44:24
    a superpower and we tend to only look at
  • 00:44:28
    one side of the equation the leaning in
  • 00:44:31
    I always think um the way I like to
  • 00:44:33
    think of it is isn't so much as a seesaw
  • 00:44:35
    is you can either be back on your heels
  • 00:44:37
    flat footed or forward Center of mass I
  • 00:44:39
    stole this from Pat Doss the founder
  • 00:44:41
    made for did nine years in the SEAL
  • 00:44:43
    Teams and so I like that that forward
  • 00:44:46
    Center of mass is great but it's it's
  • 00:44:48
    energetically demanding and you need to
  • 00:44:50
    learn how to come up to just you know
  • 00:44:51
    flat footed every once in a while now
  • 00:44:53
    when you're back on your heels that's a
  • 00:44:56
    sign that likely you were doing too much
  • 00:44:58
    time forward Center of mass no one wants
  • 00:45:00
    to talk about this but people who grind
  • 00:45:02
    grind grind rarely succeed and then just
  • 00:45:05
    take you know take off and do something
  • 00:45:08
    else I think people humans have mastered
  • 00:45:10
    this process of engaging and disengaging
  • 00:45:14
    on a longer time scale Work Hard Play
  • 00:45:16
    Hard or they'll take a long vacation but
  • 00:45:19
    what I'm talking about doing this is
  • 00:45:20
    across the day I'm talking about
  • 00:45:22
    regulating your nervous system within
  • 00:45:23
    the unit of the day or even within the
  • 00:45:25
    unit of the morning or within the unit
  • 00:45:27
    of the afternoon and I think that that's
  • 00:45:30
    a much more um useful at least to me a
  • 00:45:33
    much more useful time bin to
  • 00:45:35
    conceptualize this because the idea that
  • 00:45:37
    you're going to you know sell the
  • 00:45:39
    company or launch the thing and then
  • 00:45:40
    then you'll rest okay but you can be so
  • 00:45:44
    much more effective if you know how to
  • 00:45:45
    dynamically control your nervous system
  • 00:45:47
    in real time and great athletes know how
  • 00:45:49
    to do this great musicians know how to
  • 00:45:51
    do this even within the playing of a
  • 00:45:53
    piece of music or within a race they
  • 00:45:56
    know how to Reserve energy so that then
  • 00:45:59
    they can kick at the end or in academics
  • 00:46:02
    you learn I was always on the quarter
  • 00:46:04
    system which is a 10we system you learn
  • 00:46:06
    how to pace yourself through the quarter
  • 00:46:09
    because otherwise you're coming in
  • 00:46:11
    screeching at the end and you then two
  • 00:46:14
    get two weeks off and it's really
  • 00:46:16
    stressful you're just trying to recover
  • 00:46:17
    your health and then you're back into
  • 00:46:18
    another cycle so I think one of the
  • 00:46:20
    reasons that I'm not superb at this but
  • 00:46:22
    one of the reasons I've been you know at
  • 00:46:24
    least partially successful in
  • 00:46:25
    maintaining a a laboratory and do a
  • 00:46:28
    podcast and you know I like to think you
  • 00:46:29
    can ask the people in my life you know
  • 00:46:31
    decent you know decently effective in my
  • 00:46:34
    my personal life is that I think all the
  • 00:46:37
    time am I pushing too
  • 00:46:39
    hard you know yes or no and there are
  • 00:46:42
    times to lean go forward Center of mass
  • 00:46:44
    don't get me wrong but this can be done
  • 00:46:46
    with ph forward Center of mass can be
  • 00:46:48
    done if you wanted through drinking
  • 00:46:50
    caffeine um you know in the supplements
  • 00:46:52
    that we talked about earlier
  • 00:46:53
    pharmacology we talked about earlier the
  • 00:46:55
    main way to do it is to get in that kind
  • 00:46:56
    of inspired and motivated Pursuit but
  • 00:46:59
    then physiological size non-sleep deep
  • 00:47:00
    rest revery um all of that is very
  • 00:47:04
    useful but the foundation of that whole
  • 00:47:07
    process there's a third layer which is
  • 00:47:09
    sleep when you've when you're well
  • 00:47:11
    rested you're able to engage this
  • 00:47:14
    forward Center of mass flat-footed thing
  • 00:47:16
    at will much more easily when sleep
  • 00:47:19
    suffers everything suffers and so I
  • 00:47:21
    would say when people are say come to me
  • 00:47:23
    and they say listen I I think I have
  • 00:47:25
    attention deficit or I've got anxiety I
  • 00:47:26
    would just say how's your sleep you want
  • 00:47:28
    to always start with sleep great sleep
  • 00:47:30
    makes everything better and then once
  • 00:47:33
    that's in place then you can start
  • 00:47:34
    thinking about some of the other
  • 00:47:39
    processes um great sleep to me is you
  • 00:47:41
    fall asleep relatively easily you wake
  • 00:47:43
    up no more than once it's actually
  • 00:47:45
    pretty normal to wake up once in the
  • 00:47:46
    middle of the night and go use the
  • 00:47:47
    restroom and go back to sleep like cuz a
  • 00:47:50
    lot of people freak out when they wake
  • 00:47:52
    up and they're like oh my sleep's messed
  • 00:47:53
    up or their whoop score their Aura score
  • 00:47:55
    is off and um you know I I don't think
  • 00:47:59
    it's that big of a deal I mean ideally
  • 00:48:01
    you don't but uh you know a lot of
  • 00:48:03
    people have what's called nocturia which
  • 00:48:04
    is nighttime need to urinate so it
  • 00:48:06
    happens
  • 00:48:08
    um couple of things that the the path to
  • 00:48:11
    a really great night sleep starts in the
  • 00:48:13
    morning uh I've talked about this a lot
  • 00:48:15
    but I'll say it
  • 00:48:16
    again wake up if you want to be alert
  • 00:48:19
    get as much bright light in your eyes as
  • 00:48:21
    you can never look at any light that's
  • 00:48:22
    so bright that's it's painful to look at
  • 00:48:24
    cuz it can damage the eyes but ideally
  • 00:48:26
    sunlight so if you wake up at 4:00 a.m.
  • 00:48:27
    and the sun isn't out turn on bright
  • 00:48:29
    lights if you want to be awake but if
  • 00:48:31
    the Sun is out or one and once the sun
  • 00:48:34
    is out go outside without sunglasses and
  • 00:48:36
    yes you have to go outside you can't do
  • 00:48:37
    this through a window or through a car
  • 00:48:39
    windshield and get some bright light in
  • 00:48:41
    your eyes it doesn't have to be beaming
  • 00:48:43
    directly at you but indirectly or in the
  • 00:48:46
    general direction of the sun is
  • 00:48:48
    good wearing corrective lenses or
  • 00:48:50
    contacts is fine even if they have UV
  • 00:48:52
    filters that light can get to the
  • 00:48:54
    neurons in the eye that trigger a whole
  • 00:48:56
    set processes it sets in motion a big
  • 00:48:59
    increase in cortisol but it's a healthy
  • 00:49:01
    increase that leads to alertness
  • 00:49:02
    triggers an increase in body temperature
  • 00:49:04
    which is important for waking up there's
  • 00:49:06
    a whole set of processes there and it
  • 00:49:08
    sets a timer on melatonin release so
  • 00:49:09
    that about 16 hours later your melatonin
  • 00:49:11
    levels are going to go up how long to
  • 00:49:14
    view light well anywhere from 10 to 30
  • 00:49:17
    minutes depending on how bright it is if
  • 00:49:18
    you wake up and you go outside and it's
  • 00:49:20
    9:00 a.m. and it's beaming bright light
  • 00:49:22
    and you're on a snow field it probably
  • 00:49:23
    take 30 seconds if you're in the depths
  • 00:49:26
    of uh you know UK winter and you go
  • 00:49:28
    outside and there's a lot of cloud cover
  • 00:49:30
    maybe 20 minutes you can check your
  • 00:49:33
    phone out there you can do things out
  • 00:49:34
    you can take your coffee out there but
  • 00:49:35
    you have to get outside the the window
  • 00:49:37
    filtration is a serious isue you do that
  • 00:49:39
    every day I do it every day every day
  • 00:49:40
    and I don't get enough sun off my porch
  • 00:49:42
    behind us so I will walk up the street
  • 00:49:44
    my neighbors on you know there and I you
  • 00:49:46
    know I walk up there with my coffee I
  • 00:49:48
    often bring my journal and just kind of
  • 00:49:50
    write down whatever comes to mind get
  • 00:49:52
    some sun in my eyes um you know my
  • 00:49:55
    partner and I will you'll walk up there
  • 00:49:57
    and and we'll just chat and you know and
  • 00:49:59
    then we'll come back and you do that
  • 00:50:01
    most days if you miss a day no big deal
  • 00:50:03
    if you miss two days you're starting to
  • 00:50:04
    drift and when I say drift I mean that
  • 00:50:06
    these neurochemical systems are going to
  • 00:50:07
    start to to to get out of sync with the
  • 00:50:10
    daylight cycle shift workers is a whole
  • 00:50:13
    other business we don't have time I did
  • 00:50:14
    an episode on shift work people can find
  • 00:50:16
    that on our website um because it's very
  • 00:50:18
    particular to shift work and jet lag but
  • 00:50:21
    that Morning Light pulse is I say light
  • 00:50:23
    pulse light viewing is immensely
  • 00:50:26
    important
  • 00:50:27
    um a drift in cortisol Peak toward the
  • 00:50:30
    later day is a signature of depression
  • 00:50:31
    and waking up at 3:4 in the morning and
  • 00:50:33
    not being able to fall back asleep
  • 00:50:34
    signature of depression drift in
  • 00:50:36
    cortisol Peak so you'll you'll get that
  • 00:50:38
    drift if you don't get that light
  • 00:50:40
    exposure early in the morning that's
  • 00:50:42
    right and and so you're you're going to
  • 00:50:43
    get a pulse in a a big increase in
  • 00:50:46
    cortisol at some point every 24 hours
  • 00:50:48
    you want that to be early in the day and
  • 00:50:50
    when you want to be alert now some
  • 00:50:52
    people wake up at 10:00 a.m. right I've
  • 00:50:53
    got a friend uh who's I consider you
  • 00:50:56
    know he's kind of a mentee of mine and
  • 00:50:58
    and he likes to sleep in he's a teenager
  • 00:51:00
    he sleeps in so he's going to wake up at
  • 00:51:01
    10 but then he goes outside and he gets
  • 00:51:03
    a sunlight if you wake up at 5: again if
  • 00:51:06
    the sun isn't out turn on as many Bright
  • 00:51:08
    Lights as possible and then go outside
  • 00:51:09
    once the sun is out why because early in
  • 00:51:11
    the day you need a lot of bright light
  • 00:51:13
    in order to trigger this mechanism now
  • 00:51:16
    the second tool is that later in the day
  • 00:51:19
    as the sun is heading down it doesn't
  • 00:51:20
    have to just be crossing the Horizon you
  • 00:51:22
    also want to get light into your eyes
  • 00:51:25
    for the following reason it adjusts the
  • 00:51:27
    sensitivity of the what we call the
  • 00:51:29
    retinal photo receptors the cells in the
  • 00:51:31
    eye that detect light and makes it such
  • 00:51:33
    that nighttime light that you're going
  • 00:51:35
    to get at 8:00 or 9:00 p.m. won't have
  • 00:51:37
    as severe an effect on reducing
  • 00:51:40
    melatonin so I consider kind of your
  • 00:51:42
    Netflix inoculation because when you're
  • 00:51:44
    viewing screens at night or you're
  • 00:51:46
    unless you have built your house so that
  • 00:51:48
    all the lights are red lights and
  • 00:51:50
    they're really dim most people use
  • 00:51:52
    artificial lighting at night and that
  • 00:51:54
    can mess up sleep so if you're really
  • 00:51:57
    extreme about it you you know you make
  • 00:51:59
    your house a cave at night I don't do
  • 00:52:01
    that okay I tend to dim the lights I
  • 00:52:03
    don't like bright lights after about 700
  • 00:52:04
    or 8:00 p.m. but getting that afternoon
  • 00:52:06
    light is great because it sends two
  • 00:52:08
    signals to your brain and body about
  • 00:52:11
    where you are in time the meaning time
  • 00:52:13
    is the rotation of the earth so you get
  • 00:52:16
    your cortisol pulse early melatonin
  • 00:52:18
    comes on people who start waking up late
  • 00:52:21
    or super early and they spend all their
  • 00:52:23
    time on their phone it's not enough
  • 00:52:24
    light to trigger these mechanisms early
  • 00:52:26
    in the day but at night retinal
  • 00:52:28
    sensitivity is such that if you are
  • 00:52:31
    looking at your phone on full screen
  • 00:52:32
    brightness or you have a lot of
  • 00:52:33
    artificial lights on you're going to
  • 00:52:36
    suppress melatonin and you start
  • 00:52:38
    disrupting these mechanisms so bright
  • 00:52:40
    light early bright light in the
  • 00:52:41
    afternoon minimize bright light exposure
  • 00:52:44
    in the evening all colors and flavors of
  • 00:52:47
    light it's not just blue light this has
  • 00:52:49
    got to be responsible for a lot of sleep
  • 00:52:50
    issues a ton of sleep issues a lot of
  • 00:52:53
    people have written to me I would say
  • 00:52:54
    thousands of people have written to me
  • 00:52:56
    and said I get morning sunlight every
  • 00:52:58
    morning as best I can 10 to 30 minutes
  • 00:53:02
    and my sleep issues are resolved now
  • 00:53:04
    some people do that and their sleep
  • 00:53:05
    issues are not still resolved I would
  • 00:53:08
    say then you look to how late in the day
  • 00:53:09
    are they ingesting caffeine do they have
  • 00:53:11
    a kind of rumination issue are they
  • 00:53:13
    eating enough I mean one thing that is
  • 00:53:16
    not commonly discussed is that in order
  • 00:53:18
    to sleep well you have to eat enough not
  • 00:53:21
    necessarily right before sleep and
  • 00:53:22
    nowadays there's a big movement towards
  • 00:53:23
    don't eat within 2 hours of sleep and I
  • 00:53:26
    think it's generally a good idea
  • 00:53:27
    sometimes I obey that sometimes I don't
  • 00:53:29
    but if you don't have enough starch in
  • 00:53:31
    your system sorry low carb keto people
  • 00:53:34
    but if you're going to have sleep issues
  • 00:53:35
    unless you do other things to offset
  • 00:53:37
    that because starches and the whole
  • 00:53:40
    association with the tryptophan system
  • 00:53:41
    and the serotonin system are part of the
  • 00:53:43
    calming system there's a reason why we
  • 00:53:45
    reach for certain so-called Comfort
  • 00:53:46
    Foods when we're stressed is because
  • 00:53:47
    they increase the release of Serotonin
  • 00:53:50
    and they blunt cortisol so if you're
  • 00:53:51
    just a bag of cortisol and adrenaline
  • 00:53:54
    and you're fasting long period of time
  • 00:53:57
    it's very hard to to get quality sleep
  • 00:53:59
    now and I I think interb fasting is
  • 00:54:01
    terrific suchin Panda who really is the
  • 00:54:03
    one that kind of popularized this at the
  • 00:54:04
    scientific level anyway is a is a friend
  • 00:54:06
    and colleague of mine does beautiful
  • 00:54:08
    work but you know you need to figure out
  • 00:54:11
    how much to eat and when to eat and what
  • 00:54:12
    to eat in a way that still allows you to
  • 00:54:14
    transition to sleep so I say the light
  • 00:54:15
    viewing early the light viewing in the
  • 00:54:17
    afternoon avoid Bright Lights of all
  • 00:54:19
    colors blue blockers are fine if you
  • 00:54:21
    like them but it's not just blue light
  • 00:54:23
    that can mess up these circadian clock
  • 00:54:24
    systems any bright light any bright
  • 00:54:27
    light will do that because of the
  • 00:54:28
    spectrum of of wavelengths of light that
  • 00:54:30
    the neurons that are responsible for
  • 00:54:32
    this respond to
