It Sucks for 3 Days But It Makes Waking Up Early Effortless - Dr Andrew Huberman — Transcript
Full transcript
- 0:00how can people become a morning person
- 0:02or learn to get up early more easily and
- 0:06more regularly yeah um three days of
- 0:09pain the rest is easy so it takes about
- 0:11three days to shift the biological
- 0:14mechanisms to uh make you a morning
- 0:16person now if you are a very strongly
- 0:20genetically determined Night Owl that's
- 0:22a thing that's a thing so there are
- 0:24genetic mutations they call them
- 0:26polymorphisms that make some people
- 0:28night owls they feel best
- 0:30psychologically and physically going to
- 0:31sleep at about 1: 2 or 3:00 a.m. and
- 0:34waking up somewhere around you know 10
- 0:3711 am or noon that exists not just
- 0:41during development or teen years but
- 0:43that exists not just for social reasons
- 0:44other people are true morning people
- 0:46they feel absolutely best going to sleep
- 0:48around 8:00 p.m. or 900 p.m. 10: p.m.
- 0:52would be late for them and they feel
- 0:53great waking up at 4:00 5 or 6:00 a.m.
- 0:56okay most people feel best going to
- 0:57sleep somewhere between 10: and midnight
- 0:59and waking up somewhere between 6:00
- 1:01a.m. and 8:00 a.m. or so maybe 5:30 to
- 1:048:00 a.m. okay so those are three bins
- 1:08of the Night Owl the morning person and
- 1:11then the more typical schedule but it's
- 1:13heavily weighted toward that typical
- 1:15schedule if you look at the general
- 1:17population so if somebody wants to get
- 1:20up earlier you need to stack the four
- 1:23primary what are called zeit gers or
- 1:25timekeepers so named because some of the
- 1:27early chronobiologists that discovered
- 1:29this this stuff and the underlying
- 1:31mechanisms were German as it were so the
- 1:34number one zeit Gaber the number one way
- 1:36to shift your circadian clock which is
- 1:38this cluster of neurons that sits a few
- 1:40centimeters above the roof of your mouth
- 1:42is to view bright light at a time when
- 1:45you want to be awake aka the morning
- 1:48okay so that's why I say get outside
- 1:50look at the sun toward the sun don't
- 1:53force yourself to stare at it don't
- 1:55damage your eyes blink as needed no
- 1:57sunglasses eye glasses corrective lenses
- 2:00contacts are absolutely fine even if
- 2:01they have UV protection
- 2:04okay however if you combine that with
- 2:06another zeit Gaber the second most
- 2:08powerful zeit Gaber is exercise or
- 2:10movement so if you do some jumping jacks
- 2:12you skip some rope or even just take a
- 2:14walk while facing the sun now you're
- 2:16starting to stack different zeit gers
- 2:18and I'll explain the mechanisms in a
- 2:20moment if you then also add caffeine now
- 2:23this spits in the face a little bit of
- 2:25what I said a few minutes ago but if you
- 2:27were to add caffeine you can entrain as
- 2:31it's called the circadian clock to be
- 2:33alert at that time a bit more and I'll
- 2:35be honest if I'm going to exercise first
- 2:36thing in the morning I need caffeine I
- 2:38can't wait that 60 to 90 minutes if I
- 2:40need to jump right into exercise I find
- 2:42it's easiest for me to do 30 minutes
- 2:44after waking three hours after waking or
- 2:4611 hours after waking and a lot of
- 2:48people find that the same but of course
- 2:50exercise when you can because it's that
- 2:52important but if you want to quot and
- 2:53optimize your energy levels for exercise
- 2:55typically people will notice that has to
- 2:56do with your temperature Rhythm Okay so
- 2:58we've got sunlight we've got exercise or
- 3:01movement of any kind it could be jumping
- 3:02jacks could be walking you don't have to
- 3:04do a full workout and then caffeine and
- 3:07in some cases food I'm not big on eating
- 3:10first thing in the morning I don't like
- 3:11to eat until 11: a.m. or noon that's
- 3:14when my first meal arrives for me just
- 3:16naturally that's when I get hungry it's
- 3:17all caffeine and hydration prior to that
- 3:20but if you were to eat something first
- 3:22thing in the morning you that's part of
- 3:24the way you entrain your circadian clock
- 3:26to wake up to essentially wake you up
- 3:29earlier and then the fourth one is a
- 3:30social Rhythm if you're interacting with
- 3:32other people you're going to entrain
- 3:35your clock to that as well way yes so
- 3:37there's a socially there's a social
- 3:39component to circadian entrainment now
- 3:41the pathways for these are from the eye
- 3:43in the case of viewing light to the
- 3:45circadian clock the supermatic nucleus
- 3:47in the case of caffeine it's more
- 3:49General in the case of exercise there's
- 3:51literally a brain stem to circadian
- 3:54clock connection a big super highway of
- 3:56neuronal connections that then So-Cal
- 3:59entrains your circadian clock remember
- 4:01your circadian clock generates an
- 4:03intrinsic 24-hour Rhythm such that if we
- 4:05put you into constant dark or constant
- 4:07light you would still sleep for a given
- 4:08bout and then be alert for a given bout
- 4:10with a little bit of a nap it just is
- 4:12what would call free run it would drift
- 4:13a little later each day this is what
- 4:15happens when you go to Vegas this is
- 4:17what happens when you're in an
- 4:18environment without a lot of cues about
- 4:20the day uh the sunlight uh rising and
- 4:23setting
- 4:25cycle
- 4:26sunlight exercise caffeine and eating
- 4:29and social interactions bring your
- 4:32circadian clock into alignment with all
- 4:35of those zit gers so when I said it
- 4:38takes three days if tomorrow you want to
- 4:41start beginning the process of becoming
- 4:43an early riser you'd set your alarm for
- 4:455:00 a.m. no matter what time you went
- 4:47to sleep the night before you're going
- 4:48to get up and you're going to do the
- 4:49four things that I described maybe leave
- 4:51out food if you don't want to eat maybe
- 4:53leave out caffeine if you want to delay
- 4:54by 90 minutes it's going to hurt and
- 4:58then by the early afternoon you'll be
- 4:59dragging a bit and you just have to be
- 5:01careful to not overindulge in caffeine
- 5:03which will then cause you to fall asleep
- 5:04later then you want to go to sleep at
- 5:06your now naturally slightly earlier
- 5:08sleep time the next day you'll notice
- 5:11you'll it'll be a little bit easier to
- 5:13do the morning routine I just described
- 5:16and by the third day you ought to be
- 5:18waking up with or before the Alarm by a
- 5:20few minutes or moments because your
- 5:22circadian clock has phase shifted okay
- 5:25it's phase Advanced as we say your
- 5:27circadian clock intrinsic to you
- 5:29generates a
- 5:3124.2 or a 24.3 hour Rhythm it's not
- 5:34perfectly 24 hours and that we believe
- 5:37we don't know but the just so story is
- 5:39that it's that it's such that that
- 5:43you're able to then shift that clock in
- 5:46in one or the other direction you can
- 5:47phase advance so you wake up earlier and
- 5:49go to sleep earlier you can phase delay
- 5:51how do you phase delay well you're
- 5:52probably doing this already everyone
- 5:54nowadays pretty much qualifies as a
- 5:56shift worker by the strict and not so
- 5:58strict criteria of shift work which is
- 6:00are you doing any kind of cognitive
- 6:02activity after 9:00 p.m. are you viewing
- 6:04any kind of bright lights after 9:30
- 6:06p.m. most people would say yes so the
- 6:09the Diabolical thing about the Circadian
- 6:11Timing System is that it requires a lot
- 6:14of bright light ideally from sunlight
- 6:16but a lot of bright light early in the
- 6:18day to make you a morning and daytime
- 6:20person but it requires just a little bit
- 6:22of bright light even from an artificial
- 6:23Source after the hours of about 9:30
- 6:26p.m. till 4:00 a.m. to quash your Mel
- 6:29tonin make it difficult to sleep or if
- 6:31you sleep to make that sleep not as
- 6:33effective there's a simple remedy
- 6:34however which is and this is a beautiful
- 6:37study publishing science reports in
- 6:412022 if you view sunlight in the
- 6:45afternoon even for five minutes or so
- 6:48could be late afternoon could be sunset
- 6:50take off your sunglasses look in the
- 6:51direction of the Sun so now looking West
- 6:53you adjust the sensitivity of your
- 6:55retina the neurons in the back of your
- 6:57eye such that bright light later at
- 7:00night doesn't have quite as much effect
- 7:03to suppress melatonin and it reduces the
- 7:05Melatonin suppressive Effects by about
- 7:0750% or offsets those so I think of this
- 7:10afternoon viewing as well first of all
- 7:12it's nice to look at a sunset if you're
- 7:14indoors in environment like this even if
- 7:16there are bright lights on get outside
- 7:19for a few minutes before the sun sets
- 7:20this is especially important in Winter
- 7:23even if you can't see the Sun as an
- 7:24object get some sun light in your eyes
- 7:26and that will at least partially offset
- 7:28the effects of bright light light in
- 7:30your eyes at night partially and I refer
- 7:32to this more or less as your Netflix
- 7:33inoculation so that that night you can
- 7:35be on your phone or watch Netflix and
- 7:36it's not going to disrupt your sleep as
- 7:38much but it will still disrupt your
- 7:40sleep somewhat but let's you know unless
- 7:42like Rick rubin's very diligent about
- 7:44wearing the red lens classes I've
- 7:46started doing that as well um but if you
- 7:49don't do that you I'm guessing he also
- 7:52sees the sunset in the evening um he's
- 7:54very attached for good scientific
- 7:57reasons uh to the sunlight thing but
- 7:59these are little things that take just
- 8:01moments right they're essentially zero
- 8:03cost that can really improve your sleep
- 8:05but that's how you become a morning
- 8:06person if you want to become a night
- 8:07person you do the opposite you view
- 8:09bright light between the hours of 400
- 8:12p.m. and 10 p.m. and there then you will
- 8:15phase delay or phase shift in a delayed
- 8:18way your circadian clock making you want
- 8:21to wake up later the next morning I
- 8:23wonder if dogs count as uh social
- 8:28interaction absolutely and they have all
- 8:31of the same mechanisms we just described
- 8:33so I just thinking how can we stack that
- 8:35everything first thing in the morning
- 8:37morning walk you if you're in a place
- 8:40that's not Iceland or somewhere that's
- 8:42super high North dog social interaction
- 8:46moving around and then caffeine if you
- 8:48do or if you don't if you don't want it
- 8:50but uh if you have a dog that likes to
- 8:52run you're even better off CU it'll
- 8:54force you to run if you have if you have
- 8:56an English bulldog like I did you'd be
- 8:58lucky if you get out of bed by
- 9:00their eyes are droopy they don't and um
- 9:03uh they don't like to move but it is the
- 9:06case that dogs will naturally Orient
- 9:09toward the sun you know and people
- 9:11always ask you know do dogs have the
- 9:12same mechanisms absolutely intrinsically
- 9:14photosensitive retinal gangling cells
- 9:15the one that project to the clock and
- 9:17carry all of this um thing about
- 9:19circadian entrainment to sunlight are
- 9:22present as far as we know in every
- 9:24extent Mamon species every Mamon species
- 9:26that's that's alive today um and you
- 9:29know this is a system that evolved from
- 9:32bacteria that's very similar to the
- 9:35opsin the light absorbing molecules that
- 9:37are in the insect eye it's a very
- 9:39primordial system it's organized very
- 9:41differently anatomically in the retina
- 9:43and to me it's actually one of the more
- 9:44beautiful systems in in all of us in
- 9:47fact the one thing that no one can seem
- 9:49to defeat you're never going to biohack
- 9:51away is circadian biology this this you
- 9:54know fluctu 24-hour fluctuation in
- 9:56energy and focus you know some people
- 9:58require less sleep but we we're all um
- 10:02more or less a slave to these mechanisms
- 10:04and you know it's a good thing that we
- 10:05are because it forces us to rest
- 10:07neuroplasticity occurs during sleep it
- 10:09push down adenosine you know it takes us
- 10:11through these natural es and cycles of
- 10:13cognition I'm obsessed by the idea that
- 10:15in sleep you know the conscious mind
- 10:17obviously is not in control the
- 10:19unconscious mind can geyser up thoughts
- 10:21the brain is organizing things more in
- 10:22terms of symbols time and space are very
- 10:25uh very organized very differently in
- 10:26dreams and there's a lot of information
- 10:28to be gleaned from dreams it's just that
- 10:30we don't yet understand what the symbols
- 10:32mean the kind of classic Freudian yian
- 10:35um interpretations are certainly not
- 10:36going to be complete but you know I I'm
- 10:38so grateful that we get this thing
- 10:40called sleep and I think thanks to the
- 10:42great Matt Walker We Now understand that
- 10:44the whole thing of all sleep would I'm
- 10:45dead is a really dumb mindset and you
- 10:49know my team at The hubman Lab podcast
- 10:51we sometimes joke that we win by
- 10:53sleeping you know when we're in the peak
- 10:55of things we all encourage each other to
- 10:57like get rest you know get rest like we
- 11:00really prioritize sleep traveling should
- 11:03be about the journey not the chaos of
- 11:05packing which is why I have been using
- 11:07nomatic backpack and carryon Pro for
