00:00Welcome to the Huberman Lab podcast, where we discuss science and science-based tools for everyday life.

00:08Recently, the Huberman Lab hosted a live event at the Chicago Theater in Chicago, Illinois.

00:13The event consisted of a lecture entitled The Brain-Body Contract, followed by a question-and-answer session.

00:18We wanted to make sure that the question-and-answer session was available to everybody, regardless of who could attend in person.

00:24I also want to make sure to thank the sponsors of that event, which were AG1 and 8sleep.

00:308sleep makes smart mattress covers with cooling, heating, and sleep tracking capacity.

00:34One of the key things to getting a great night's sleep is to make sure that the temperature

00:38of your sleeping environment is correct.

00:40And that's because in order to fall and stay deeply asleep, your body temperature actually

00:43has to drop by about one to three degrees.

00:45And in order to wake up feeling refreshed and energized, your body temperature actually

00:50has to increase by about one to three degrees.

00:52With Eight Sleep, you can program the temperature

00:54of your sleeping environment in the beginning,

00:56middle, and end of your night.

00:57It has a number of other features

00:59like tracking the amount of rapid eye movement

01:00and slow wave sleep that you get,

01:02things that are essential to really dialing in

01:04the perfect night's sleep for you.

01:06I've been sleeping on an Eight Sleep mattress cover

01:07for well over two years now,

01:09and it has greatly improved my sleep.

01:11I fall asleep far more quickly,

01:13I wake up far less often in the middle of the night,

01:15and I wake up feeling far more refreshed

01:17than I ever did prior to using an Eight Sleep mattress cover.

01:20If you'd like to try Eight Sleep,

01:21you can go to eightsleep.com slash Huberman

01:24to save $150 off their pod three cover.

01:27Eight Sleep currently ships to the USA, Canada, UK,

01:30select countries in the EU and Australia.

01:32Again, that's eightsleep.com slash Huberman.

01:35AG1 is an all-in-one vitamin mineral probiotic drink.

01:39I've been taking AG1 since 2012,

01:41so I'm delighted that they sponsored the live event.

01:44The reason I started taking AG1

01:46and the reason I still drink AG1 once or twice a day

01:49is that it provides all of my foundational nutritional needs.

01:52That is, it provides insurance

01:53that I get the proper amounts of those vitamins,

01:56minerals, probiotics, and fiber

01:58to ensure optimal mental health,

02:00physical health, and performance.

02:02If you'd like to try AG1,

02:04you can go to drinkag1.com slash Huberman

02:07to claim a special offer.

02:08They're giving away five free travel packs

02:10plus a year's supply of vitamin D3K2.

02:13Again, that's drinkag1.com slash Huberman

02:16to claim that special offer.

02:18And now, without further ado, the question and answer session from our live event at the Chicago Theater in Chicago, Illinois.

02:41I turn 70 soon. What is your best advice to keep my brain healthy in old age?

02:45terrific question. The advice I would give to you as somebody about to reach 70 is the same advice

02:51I give to anybody, which is that essentially all of the things that improve cardiovascular health

02:57and perfusion of your bodily tissues are going to improve functionality of the brain. Because,

03:05of course the brain as a rich consumer of fuel requires very good portals to deliver those fuels

03:15and that capillaries, micro capillaries and arteries and so forth need to be clean and clear.

03:20That's the big one. This is why I think the prescription now is generally accepted and here

03:26I'm borrowing from my friend Peter Attia but about 150 or maybe as much as 200 minutes of

03:31so-called zone two cardio per week movement that you can just barely carry out a conversation

03:36is going to be very useful. One thing that's often not discussed is that load-bearing exercise of

03:41some sort is going to be better provided your body can tolerate it, but you should do something that

03:45you can do consistently over those long durations without injuring yourself. But there's a very

03:52interesting literature about how load-bearing movements actually generate the release of

03:57hormones, yes, hormones from bone that actually cross the blood-brain barrier and may influence

04:03health of neurons in brain areas such as the hippocampus. And there I'm extending from

04:08preclinical data in animals to humans, but there's some human data starting to emerge that that's true.

04:14It's also true, and there's a wonderful paper out just today or yesterday from Dr. Andy Galpin's

04:20lab and collaborators talking about how if you look at cognitive health, it's highly correlated

04:26with things that relate to strength.

04:29And that is not to say that you should just do strength training exercise,

04:31but we know that all people, truly all people,

04:35should be doing some sort of resistance training two or three times per week.

04:38And we know that grip strength and increasing asymmetry in grip strength

04:43between the two hands is one of the indicators of deficits in control

04:48from the brain out to the periphery, and it's correlated with cognitive decline.

04:52There's also some interesting data about how when the feet become floppy and kind of flaccid or the lack of ability to extend one's toes.

05:01I'm still working.

05:02I've been wearing this toe spreader thing.

05:03Has anyone tried those?

05:04Those hurt.

05:05Those hurt.

05:06I broke this foot a bunch of times.

05:07But I'll tell you, when you get better at spreading your toes, it's really exciting.

05:11And it's really exciting for several reasons.

05:13It's really exciting because there's more stability in your feet.

05:15You can run and move and do things better without pain.

05:18But in addition to that, believe it or not, just as one of the first things that they're going to do when you come into this world is scrape the bottom of your foot and look for the Babinski reflex, which is a neural transmission reflex, as all reflexes are.

05:31But it's testing essentially the health of the nervous system that over time, you know, again, there are many correlates of dementia, many, many correlates of dementia.

05:40But an inability to finely control the extremities is certainly one of them.

05:45So strength training, cardiovascular training, these are kind of stereotyped answers for your question, and yet those are really the prime movers against cardiovascular and cerebrovascular disease.

05:58And then, of course, there's, you know, I'd be remiss if I didn't throw in something that was a little bit more edgy, because that's what I do.

06:05You know, there are interesting data about the use of drugs to increase acetylcholine transmission, right?

06:12I mean, I was visiting a Nobel Prize winner at Columbia to learn about his incredible work some years ago

06:19and saw that he chewed no fewer than five pieces of Nicorette gum, something I don't recommend during this short meeting.

06:25And I said, what is this all about?

06:27He said, well, you know, I don't smoke anymore because I don't want lung cancer.

06:30But, you know, he said nicotine is, you know, protective against Parkinson's and Alzheimer's.

06:35I was like, how can that be?

06:36And he said, well, you know, it decreases in neuromodulation.

06:40Dopamine and acetylcholine correlated with cognitive decline, keeping your brain sharp, and so on and so forth.

06:45So I'm not encouraging people to take nicotine.

06:47It increases blood pressure, vasoconstriction.

06:50But it's an interesting consideration.

06:53You know, some of the emerging cholinergic and dopaminergic drugs or ways to increase acetylcholine and dopamine are certainly intriguing.

07:01And I won't tell you who that person is, but his name is Richard Axel.

07:04Next question.

07:05Yeah.

07:06How can I optimize sleep while working 24-hour shifts as a firefighter, 24 hours on, 48 hours off?

07:13Okay.

07:13And this probably also pertains to new parents.

07:17And it probably also pertains to anyone that's going through a particularly stressful time

07:22where you're micro-waking throughout the night, so not just firefighters.

07:25So what do we know?

07:26We know, based on really good data, that shift work is bad for us.

07:31It's just bad.

07:32We're a diurnal species.

07:34We're not nocturnal.

07:35But thank you, thank you, thank you, shift workers, because you essentially keep us all safe and make the world go round.

07:42And so we need you and we want you healthy.

07:45So one of the main things is that you can make sure that you stay on the same sleep-wake schedule for at least two weeks.

07:54It's the swing shift that's really the worst.

07:59You can tell your boss I said that.

08:01and if they won't agree and you're doing this 24 hour on 24 hour off there are a couple of things

08:07that are really important first of all the main way to wake up your nervous system even though it

08:12might not feel like a triple espresso is going to be that light exposure to the eyes and if you can't

08:19get it from sunlight is going to be from any bright artificial light I'm not a huge proponent of the

08:25daylight simulators. They're very expensive. You can simply buy a 900 lux LED far more inexpensively.

08:32I don't have any relationship to any company that sells these, but you can find them on

08:35Amazon or wherever you happen to prefer to purchase things. Or you can just get really

08:40close to a bright light anytime you're trying to wake up, even if you don't feel that it helps you

08:46wake up very much, mostly for the melatonin suppression, because bright light will very

08:50acutely suppress melatonin. And then the real question from shift workers always seems to be,

08:54Should I catch up on sleep or is that going to be problematic?

08:58Should I just stay up into the next cycle?

09:01And the answer there is a little bit nuanced, but the best answer I can give across the

09:05board is if this is a pattern that you're going to be in regularly over, say, months

09:10or years, then get whatever sleep you can.

09:14Get whatever sleep you can.

09:15If it's something that you're doing somewhat acutely, like you're traveling to Europe and

09:19you're just going to force yourself to stay up a day and a half, then in that case, I

09:23would say no need to to get the maximum amount of sleep just try and stay with the local schedule

09:30we have an entire episode about shift work that somehow um maybe didn't get as much recognition

09:37as it should have um for shift workers and we'll try and get it out in better form we don't always

09:41succeed in you know top carding things in a way that gets them out to the most people uh one thing

09:46i will say is an opportunity to announce that our website hubermanlab.com is completely revamped so

09:51it's highly searchable. It'll take you to exact timestamps and is and now you can segregate out

09:57timestamps from newsletters from all this stuff. So thanks to a lot of effort by my amazing team,

10:02you can now navigate that site with a with real precision. So if you want to say ADHD, Adderall,

10:09kids, yes, no, for instance, it will take you to precise timestamps that will address those issues.

10:15Next question, please.

10:17How does hypnosis therapy work?

10:19Well, this is a very interesting topic to me

10:22because my colleague,

10:25Associate Chair of Psychiatry at Stanford, David Spiegel,

10:28is a world expert in hypnosis

10:31and its neural underpinnings

10:33and its use for clinical applications.

10:36His father was a hypnotist, also a psychiatrist.

10:41And when people hear hypnotism,

10:43they think of stage hypnotism

10:44and being up on stage and doing things you don't want to in front of other people.

10:49But really, when we're talking about clinical applications or wellness applications of hypnosis,

10:54we're talking about self-directed hypnosis.

10:56I really wish there was a better name because I don't think hypnosis is going to advance very far as a field, frankly,

11:02because everyone thinks hypnosis.

11:05And it would be like if psychedelics were just called drugs, right?

11:09We were taught in the 80s that drugs are bad and that your brain on drugs looks like an omelet.

11:14and that's bad. And if you like omelets, they're still bad. And drugs of abuse are bad. And actually,

11:21I hope we can talk briefly about psychedelics at some point, because I do think there's a little

11:25bit of a runaway train around the topic of psychedelics now. I think we need to be very

11:29careful how we approach that entire landscape. But hypnosis essentially works by allowing someone

11:36to place their own brain into this very unique state. Earlier, we were talking about neuroplasticity,

11:41And we talked about the fact that neuroplasticity involves intense focus followed by deep rest in the form of deep sleep or non-sleep deep rest, maybe even Rick Rubin-ing it and just kind of like laying there.

11:54Hypnosis is different because hypnosis is in a state in which your focus is very narrow, the context is very narrow, but you're very, very relaxed.

12:06So maybe the Rubin example of being brain active and body very still is a bit more like hypnosis, to be fair.

12:15Why would it be the case that David Spiegel and his dad have literally a tool that is approved by the major American Psychiatric Association,

12:27where they can figure out how hypnotizable you are by having you look up and try and close your eyelids while continuing to look up?

12:33The so-called Spiegel eye roll test.

12:34Sounds pretty wacky, right?

12:36This is like TikTok level wacky.

12:39Well, the reason is you have cranial nerves,

12:41so they sit more or less near your neck,

12:43that allow you to direct your focus, your eyes upward.

12:47And then you have cranial nerves that have your eyes go down.

12:50And the cranial nerves that drive your eyes up

12:53are associated with alertness and eyes open, no surprise.

12:57And the cranial nerves that are associated with pointing your eyes down

13:01and closing your eyelids are associated with what?

13:03With drowsiness, sleep, and lack of alertness.

13:05There's sort of a push-pull in the autonomic nervous system.

13:08And Spiegel, Spiegel's daddy and him, figured out, because they're geniuses,

13:15that if somebody can maintain upward gaze while closing their eyelids, two things happen.

13:20One, you'll see the whites of their eyes, and it's pretty creepy.

13:24Two, that means they're highly hypnotizable,

13:26because that is a reflection of the probability that they can enter a brain state

13:31in which they are both very awake and very relaxed.

13:35Pretty cool.

13:36Now, if that sounds kind of wacky because you're just looking at the periphery,

§02Transcript — part 2

13:39keep in mind that one of the primary entry points for diagnosing concussion

13:43is to shine a light in one eye and have that pupil constrict

13:48and then see whether or not the other pupil constricts,

13:51the so-called consensual pupillary reflex.

13:54Although technically, and I've been bothered by this from day one,

13:56it should be called the non-consensual pupil reflex

13:59because the other eye doesn't have a choice if everything's working.

14:04In any case, if you have a hard hit to the head, you'll see that you shine light in one eye, the pupil constricts in the other one, stays really dilated and then you go, okay, get this person in the emergency room.

14:17Because there's been a severing of the connections between the two sides of the brain.

14:19So looking in the eyes and trying to deduce what might be happening more centrally within the caverns of the skull and the brain is not a new thing.

14:28It is a primary diagnostic tool in neurology.

14:31It's also how your parents knew that you were taking drugs when you came in the door because your pupils were like that big.

14:37And that reflects a difference in autonomic arousal.

14:41Basically, stimulants, those people dilate their pupils.

14:44This is also why the story about belladonna, people intentionally dilating their pupils to trick people into thinking that they were attracted to them.

14:52I thought about this one a lot, too.

14:54It's like not a precursor to good relationship.

14:57like someone's using their physiology to pretend that they're attracted so the other person thinks

15:02that they're attracted so that they might become attracted. Anyway, it's a recipe for failure,

15:05almost as bad as most of the dating apps. Oh, I would know I'm not on them, but from what I hear.

15:10Okay, so where were we? Hypnosis. When you are in a state of elevated attention but very relaxed,

15:20guess what? Neuroplasticity occurs much faster because you're essentially marrying the two states

15:26that are normally divorced, which are heightened levels of attention first and then deep rest.

15:31You're essentially putting the nervous system into a more, I wouldn't call it hyperplastic state,

15:36but a more plastic state. And for people that are highly hypnotizable, the success rates at,

15:43for instance, smoking cessation, pain relief are pretty impressive. Spiegel Lab has published a

15:50number of these. So I think self-hypnosis is a very interesting tool. I just hope that they rename it

15:54so that it stands a chance of getting off the ground.

15:57I mean, one of the things that you learn as a public-facing educator

16:00is that what things are called has a great impact on whether or not

16:04they achieve any kind of use in the world.

16:09Hence why I decided to swallow the difficult pill of partially renaming Yoga Nidra

16:16as non-sleep deep rest.

16:18I don't like to do that.

16:19Yoga Nidra has more than a thousand-year history.

16:21but it's when people hear yoga nidra unless they are very open-minded they hear magic carpet

16:27they hear levitation and it's unfortunate and that's not how i feel but for years i talked

16:31about yoga nidra it's so cool it's like sleep state but it's like yeah i'm like yoga nidra

16:36okay and but if you come from a culture where that's discussed they're all about it and so

16:41non-sleep deep rest you know i felt like all right leave my name out of it you know i'll be

16:46dead eventually i mean i'm in this line of advisors right i'm like approaching 50 i'm like

16:50I'm winning in my lineage, but should I be fortunate enough to live past bullet cancer or car crash far enough,

17:01then NSDR hopefully will persist, and I don't need a piece of it.

17:05It's just the hope is that people will learn to put themselves into brain states that can be adaptive for them.

17:09So it'd be nice if someone could come up with something other than hypnosis.

17:13I think Spiegel would agree.

17:15Super interested in psychedelics as medicine, to be done with somebody with experience.

17:19worried about unlocking mental health conditions. Yeah, you should be. What does the research say

17:24and what are your thoughts? Okay. Barbed wire question. We like that.

17:35Psychedelics. Well, let's just back up a little bit and acknowledge one thing that's more important

17:41than psychedelics or anything else when it comes to rewiring the brain, which is that ultimately

17:47rewiring of the brain is about shifts in neuromodulators. Dopamine, serotonin, epinephrine,

17:54norepinephrine, acetylcholine. And it's no coincidence that, you know, SSRIs, selective

18:01serotonin reuptake inhibitors, have been one of the major entry points for attempts to treat

18:06things like depression over the last 20, 30 years or more. When I was in college, there was,

18:12that's when the book Listening to Prozac came out. But prior to that, there's a long history of

18:16drugs, prescription drugs in that case, to change levels of neuromodulators like serotonin or

18:22acetylcholine or dopamine in an attempt to cure or treat a disease. But keep in mind, despite the

18:29varied success of SSRIs, a topic unto itself, that there's a strong belief, and there has been for a

18:36long time, that if SSRIs worked, it wasn't because the depressed brain is deficient in serotonin,

18:43but rather because increasing serotonin offered the opportunity to increase neuroplasticity.

18:48So there's a different way of thinking about it.

18:50And that's a segue for saying that when you say psychedelics, that's a broad category of drugs.

18:55Nowadays, people even lump ketamine into that, although technically it's not a psychedelic.

19:00But the sort of classic, if you will, psychedelics are LSD, lysergic acid, diethylamide, and psilocybin,

19:07aka mushrooms, although it comes in other sources as well.

19:10The major effect of psilocybin is to stimulate a particular serotonin receptor, which has elevated density in particular brain areas.

19:20And indeed, there are many recent clinical trials, many, let's just say 12 to 20 good-sized clinical trials done in diverse locations on the planet,

19:34many at Johns Hopkins and UCSF, some in Switzerland, showing you that enhancing,

19:41and here you notice I'm using the mechanistic language, enhancing the transmission of the

19:46release of serotonin and activating particular serotonin receptors leads to an opportunity for

19:52more what? Neuroplasticity. Now, I say it that way, not to add a bunch of word soup, but because

20:00Because the real question is whether or not the experience that one has while under the

20:06influence of psychedelics is critical to the clinical outcome.

20:14Or a growing idea, just as a hypothesis, I think is equally interesting is that it's

20:19the serotonin itself and that the things you see, the things you hear, the things you experience

20:25are not relevant.

20:27Now, I have some experience with psychedelics.

20:31I had a bad time on psychedelics as a teenager.

20:34I was also pretty wayward youth, but I've had a bad trip on LSD.

20:38For years, I was scared that people were going to dose me with LSD after that.

20:41It was so bad.

20:43I think across the board, we can say kids doing psychedelics just seems like a bad idea.

20:48Their brains are already hyperplastic.

20:49If you have a predisposition to bipolar type issues or schizophrenia, it can exacerbate those issues.

21:00And certainly, certainly, certainly if you don't have adequate support in the form of somebody that can guide you through the sessions as well as the pre-sessions, which are not done with psychedelics, as well as the so-called integration afterwards, it can be a really slippery slope.

21:14I know examples of people really suffering in the aftermath of psychedelic journeys.

21:19Now, there are a few interesting points as well, and it wouldn't be fair if I didn't say that several, if not many, individuals who have had so-called treatment-resistant depression, at least in these clinical trials, have reported feeling far better after psilocybin therapy.

21:37But that psilocybin therapy was done with several pre-sessions, then the psychedelic sessions, then several after sessions, and it's not always the case that things turn out well.

21:46So I think it's early days. What is interesting and I think important is to recognize that psilocybin and the structure of psilocybin is very similar to serotonin itself. Very similar. But it activates particular receptors. A lot of people don't realize how similar to serotonin it is.

22:04And that microdosing psilocybin, I should say the data on microdosing psilocybin, something that's increasingly popular, is not particularly compelling.

22:14It's not clear what it does. It's not clear if it's of any use.

22:20And I think the danger here is that we end up in a situation as we did with, frankly, with cannabis.

22:25And by the way, I'm not somebody who demonizes cannabis.

22:27I think it has its uses for certain people.

22:29but very high THC concentration cannabis can be a problem, especially with people that have a

22:34predisposition of psychosis. And anyone that tells you that cannabis isn't addictive, just say, great,

22:40like, don't smoke weed for a week. Let's see how you do. Yeah. And let's go on a plane trip together.

22:46All right. And how are you sleeping? And, you know, so I think the chronic cannabis users are starting

22:53to take note of some of the issues it causes. But again, there are some clinical applications.

22:57Now, when it comes to the sort of the high-speed trained psychedelics like DMT, that's far less data available there.

23:07And then MDMA, assisted psychotherapy for the treatment of PTSD, they're the data I think are more robust.

23:12And I think we're likely to see legalization or at least decriminalization in the next few years.

23:17But keep in mind that MDMA is methylene-dioxymethamphetamine.

23:22So for people that like dopaminergic states, it's a particularly compelling state to be in, so much so that they could overindulge in MDMA.

23:31And then there's the issues of purity, and I could do a five-hour podcast on this right now.

23:35So I think the important point is approach with caution.

23:38Kids, absolutely not.

23:41And I think it's an exciting landscape, very exciting.

23:45And whereas a discussion like the one we just had would have gotten me fired a few years ago.

23:51I mean, Stanford has big programs now, a lot of philanthropy, federal grants, and many laboratories focused on the study of psychedelics.

23:59So, you know, I would say stay tuned, but keep in mind that increasing neuromodulator levels very acutely,

24:07whether or not it's with a prescription drug or whether or not it's with psychedelics,

24:11is really what lies at the heart of the recovery, the potential recovery, I should say,

24:16or the negative effects that happen to occur in anyone that embarks on the psychedelic journey.

24:22Do people who meditate need less sleep than people who don't?

24:26Oh, that's interesting.

24:28Well, we know that from a study by Wendy Suzuki, who I believe, if NYU made the right choice,

24:35and I think they did, is now the Dean of Arts and Sciences at NYU.

24:39She ran a memory lab for a long time.

24:41She has data showing that even 10, I think it's 13, but as little as 10 minutes of meditation,

24:48so it'll be sitting still, breathing, focusing on your breathing, directing one's attention to third eye center, etc.

24:55We don't have a third eye.

24:57The pineal is thought to be the third eye, but I don't know why.

25:00It's a light-sensitive tissue deep in the brain, but maybe that's why they call it the third eye.

25:04But in any case, that type of practice has been shown to increase memory focus, a.k.a. learning.

25:11But there's some interesting footnotes in those papers, which point to the fact that when people meditate too close to bedtime, oftentimes they have trouble sleeping because basically meditation is a focusing exercise.

25:24It's a perceptual exercise. I don't think meditation is anything mystical. It's a self-directed shift in your perception to what? To your interoception, to your internal state, as opposed to anything beyond the confines of your skin.

25:35There's nothing mystical about that. And then in that state your brain starts to

25:41generate patterns of activity that are distinct from when you're sharing your attention between what's going on internally and what's going out

25:47What's happening out in the world, right?

25:49I think we need to demystify what people have cloaked as mystical and when I say cloaked

25:53I don't think that the people that meditate for thousands of years thought that there was anything

25:59mystical about it, but sometimes what we experience there can feel mystical

26:03So if you have trouble sleeping, I recommend doing some sort of non-sleep deep rest practice like NSDR, aka Yoga Nidra, although those are different.

26:14NSDR generally lacks the intention piece.

26:18and the ones that I put into the world,

26:22we've stripped away the intentions

26:24and we've stripped away any kind of language

26:25that would make you think that there was some sort of,

26:30let's just say, like cultural aspect to it,

26:33which again is admittedly a bit unfair

26:36to the origin practice of Yoga Nidra,

26:38but the problem again is that in Yoga Nidra

26:41you're going to be doing intentions and hearing language

26:43that for some people, not all,

26:45might divorce you from the wish to do it.

26:47in any case non-sleep deep rest done at any time of day but especially if you fall asleep in the

26:53middle of the night is going to be useful for helping you fall back asleep whereas meditation

26:57again is going to enhance your level of focus so I don't think it's a good practice if you're if

27:04you have trouble sleeping now to finally answer your question if you meditate can you afford to

27:09sleep less my friend Matt Walker would say no however many of us can't sleep as much as we want

27:16to. And many of us are not like Matt, where we can wake up without an alarm clock. I'll just keep

27:21sleeping and sleeping, unless I went to bed at like eight o'clock. This is actually interesting.

27:25There's an asymmetry to your sleep needs. If you go to bed, remember that old adage, you know,

27:29every hour before midnight is worth two after. Well, it turns out that for people that are meant

27:34to be early risers, going to bed at eight, you'll wake up at three or four feeling great. You go to

27:38bed at 11, you feel groggy, and there are good reasons to explain that. But Matt would say that

27:45you need your sleep, period. I'm more of the camp based on my read of the data. And yes,

27:50we are allowed to disagree and still be friends. It's allowed. In fact, Matt's going to do a series

27:58on sleep with our podcast, even though he has a terrific podcast of his own, where we maybe

28:03debate a little bit of this, that there are ways that you can at least replace the feeling of

28:09wakefulness that you would have lost if you don't sleep enough. And for me, really, that's why NSDR

28:13became such an attractive tool to do for 10 or 30 minutes each morning if I didn't sleep enough

28:19the night before. I first learned about yoga nidra actually at an addiction recovery center,

28:24trauma recovery center in Florida in 2017. I have a friend, a super talented trauma therapist who

28:31also treats addiction that I've sent many, many people to, and he has this kind of seemingly,

28:37wizard ability to get people who have been addicts to not be addicts. And one of the tools he uses

28:46is yoga nidra every morning for 30 minutes and eventually an hour, which seems like a lot. But

28:53then he also has these people wake up very early, maybe an hour before they would normally wake up

28:59and go into that liminal state between sleep and wakefulness. Now, my experience is that 10 to 20

29:05minutes of NSDR yoga nidra is sufficient to offset some sleep loss and allow at least me to function

29:12and many people report the same we have a study going with the sleep laboratory at Stanford to

29:17explore this in more depth and what I can tell you because I'm involved in some of this work is that

29:21there are several military units because they have no opportunity to get sleep because they're working

29:27that have to rely on tools like this in order to be able to function at their highest level

29:33and I'm sure they will tell you as I will that they prefer to get eight to ten hours of sleep

29:38but guess what they can't and so I think that's an important takeaway is that we don't get to pick

29:43how much we sleep unless you're going to be completely neurotic about your sleep hygiene

29:47which makes you kind of a less interesting person in life is what I'm told you know going to bed at

29:53eight is great like some or most of the time but you got to stay up every once in a while I mean

29:58after they released Chimp Empire on Netflix, I discovered that NSDR is a very valuable tool

30:05because, and by the way, Chimp Empire and Succession have a lot of parallels. And if you watch one,

30:11I sort of, I interleave Chimp Empire Succession, Chimp Empire Succession, and you start to realize

30:15like, whoa, like we're pretty similar. And then you look at the world differently, I promise.

30:22Your podcast has positively changed the lives of so many people, including me. How has it changed

30:27your life? Okay. I wasn't expecting that one. Thank you, Samantha. Well, first of all, I mean,

30:36as this little 11-year-old told me, I mean, this is essentially what I've done my whole life.

30:43I'm a fairly private person. Believe it or not, I'm pretty introverted. I spend a lot of time alone,

30:48and I think that's required for me to, you know, I basically have four modes,

30:54four modes one I'm either readying myself through sleep

30:59and NSDR to do one of the other three modes maybe there's a fifth mode or I'm in one of

31:08these other three modes which is I'm either foraging for information organizing that information or

31:12dispersing that information or getting ready to do it all over again and then there's this

31:18relaxation vacation thing that they keep telling me about but then I went to Italy and then like

31:22Rick and I like just like hung out there and um and it didn't feel like work I also discovered

31:28some really great podcasts I don't know I think one of the coolest podcasts out there if you like

31:34rock and roll which I love is a history of 500 songs by Andrew Hickey's podcast on rock and roll

31:40I like the nerdy podcast it's like a graduate or an education in rock and roll it's so cool

31:45um and you'll learn a lot about music and history and the mobs involved and all that stuff and from

§03Transcript — part 3

31:51when I was told like Al Capone used to sit there, right? His exit was there, you know, so it was

31:56weird, right? Yeah. And then he died of syphilis. And like, so I don't know how I feel about all

32:00that. Um, but they told me that. Um, so I think the podcast has been wonderful, um, as an opportunity

32:10to share things that I love. Um, if I had my way, it would be more like this, although more of a

32:16dialogue, frankly. It's changed my understanding of what the world is like. I certainly get

32:26critique, and that's good. But again, I was raised by iconoclasts, in particular, my postdoc

32:33advisor, Ben Barres, who unfortunately, as I mentioned, is dead because I worked for him.

32:37and but you know he was he really encouraged all of us in his lab and and and often we were very

32:46close friends I spent the last year of his life recording interview with him there's actually a

32:49documentary coming out about Ben and then I'm going to release the audio interviews with Ben

32:56which he approved by the way and you'll get to realize that the history of what you see is often

33:01not what the dead person really did or said it's going to be fun so I can't wait till they release

33:06this documentary and then Ben gets to have his voice infused and it'll be a

33:10cool documentary but as some of you know that like what appears to be and what

33:15was in the historical narrative is not necessarily what it what really happened

33:20but that's just life so I suppose the short answer is that you know I feel

33:24very honored with the opportunity very very honored and you know it's a

33:31challenge at times I suppose that the major challenges are when things are

33:34taken out of context, like little clips and things of that sort. Being misunderstood doesn't feel

33:39good, but look, at the end of the day, I feel like the luckiest person in the world because I get to

33:46spend my time learning. So it's either, you know, I'm foraging, I'm organizing, or I'm dispersing

33:52information that I also want and that I find incredibly useful, or if not that, then certainly

33:59informative and at times enchanting as well. So I try and focus on the positive and I have a number

34:05of practices that help me do that. And I am somebody who engages on social media. I'm not a

34:11post and ghost kind of person. I want to understand. I think that, you know, cuttlefish are super

34:16interesting, but human beings are super interesting too. And I have a strong drive for mastery, but

34:23also I do have a strong sense of justice and that can be problematic at times. I define justice as

34:30feeling like there's something for us to do about something. Like seeing something that upsets us

34:35or that excites us is great but then if you have a strong sense of justice you feel like there's

34:39something you need to do about it and not everybody feels that. And then of course a desire to

34:43understand and I think for reasons very personal to me that relate mostly to just having a kind of

34:50incredible array of experiences in life, many of which were like shocking, disturbing, exciting,

34:56enchanting that I want to understand. And so, you know, it's changed things, but you know, it's like,

35:03I don't know, I got one truck, one watch. I, you know, it's not to say that I don't care about

35:09having things. There are a few things I really love, but like mostly like I'm just thinking about

35:13the podcast we got to record on Monday, which is about willpower and tenacity. And if I don't stop

35:18myself, I'll give it right now. So what do you feel is the next big thing to come to the forefront

35:24in the health space? Thanks for this question. One is non-protein amino acids. I love these

35:33debates online because I know that there's something there. It's so cool because I grew up

35:38and seeing these debates and you know there's something interesting there because people are

35:42debating about it, but the debate isn't what's interesting. It's almost always the thing that

35:46people aren't talking about that's sure to surface at some point. And you know, right now there's this

35:51obsession with like seed oils. It's like seed oil, seed oils. And I can't demonize seed oils. All the

35:56data say that if you separate out their caloric load, there's nothing inherently bad about seed

36:01oils and et cetera. I don't know. It's still in emerging literature, but there was a scientist at

36:07Stanford, Ed Rubinstein, who passed away at a ripe old age, a brilliant scientist who talked about,

36:16and I had a lot of discussions with when I was a postdoc about non-protein amino acids.

36:21Turns out his son is a neuroscientist at UCSF.

36:24His other son's a physician at UCSF.

36:26So it's another one of these low-performing families.

36:30And all wonderful people.

36:33And, you know, Ed had data that, you know, unlike a lot of animals like birds,

36:41there are certain amino acids which are non-protein amino acids that exist in fairly

36:48high density in seeds and nuts which is not to say that seeds and nuts are bad right i had almonds

36:53this evening okay so please um but non-protein amino acids are similar enough to mammalian

37:03protein amino acids that if they are consumed in abundance and perhaps especially in liquid

37:11form that they may, again may, because this is about the future, this isn't about what we know,

37:16this is about where I think there's an interest in growing interest, they may be able to incorporate

37:20into certain proteins of our tissues of our body that potentially, Ed thought, could lead to

37:26misfolding of those proteins and may explain certain forms of neurodegeneration and other

37:31neurocognitive challenges. So I think non-protein amino acids are going to be an important

37:37discussion. Now, there are lots of non-protein amino acids that don't come from foods, but I

37:43think the discussion around non-protein amino acids from foods is going to be very interesting.

37:48So that's one area. The other area, and perhaps you picked up on this a little bit tonight, is that

37:53I like the nuts and boltsy stuff around stress, neuroplasticity, but the high-level stuff.

37:58you know I think you know the relationship between you know structured

38:05thought abstract thought I'm not interested in the free will discussion I

38:10just feel like that's a career ender I'm friends with Robert Sapolsky and he's

38:14got a great book coming out about this called Determined so he obviously

38:18doesn't believe in free will but he's far smarter than I ever could be and it

38:22just feels like I don't know that there's an endpoint with that one but

38:27If anyone could find it, it would be Robert.

38:30He's oh so smart.

38:32But I think that the higher level stuff,

38:37creativity, abstract reasoning and thought,

38:40defining and better understanding the different states

38:43that we can go into in waking.

38:45And I confess, without a hint of sheepishness about it,

38:50that I also think the notion of spirituality

38:53and the belief in things that are beyond our current and conscious understanding is super

39:01interesting. I think that, you know, as a species, we are, we've been challenged and conflicted from

39:09go, at least that's what the historical scripture tells us, and that it's sort of inherent to our

39:16experience that life is challenging and perplexing and also wonderful. And so I think a better

39:22understanding of how to navigate all that. I mean this like this stuff in our

39:27skulls, except for the eyes which by the way are your two pieces of brain that

39:30are not in your skull, the retinas, I have to point that out. You know it's

39:36it's tricky and we're trying to use that very tissue to understand it and so I'm

39:42intrigued by the possibility that there are certain aspects of self that maybe

39:48We are not intended to be explored because they are not really of us, right?

39:56Brains interacting with one another is an interesting area, certainly for scientific

39:59exploration, but I'm fascinated by and excited about the possibility that at some point our

40:06species will both understand the mechanics of our emotions, mechanics of our thought

40:12process, creativity, and so on, but that we will also allow room for the stuff that we

40:18We can't explain with science and to allow room for that in our life experience because

40:24I also believe that can be powerful.

40:27And while understanding things in great detail and putting mechanism and utility around that

40:33and applying that is wonderful, it's the stuff of my life, which is obvious, I also think

40:41that there's great value in not trying to control and understand everything and enjoying

40:47the mystery of things that are clearly greater than us.

41:01How do you balance having fun with having such a rich

41:03knowledge and passion in neuroscience and optimization?

41:07Fun.

41:10People ask me, like, what do you do for fun?

41:11I think people think I do all the protocols.

41:14It's like, sure, I get my sunlight, I drink my water,

41:17I do them, but fun.

41:25I like learning.

41:27I like learning.

41:28I do enjoy physical movement.

41:30I like learning.

41:31You know, for me, okay, so for me, it's the little things.

41:35I don't know.

41:36Maybe I'm weird.

41:38Certainly, I've been told that.

41:40Like the other day, there was a frog in my swimming pool, and he was just like sitting there like,

41:44and and I just like spend some time looking at him back and forth and and then I had all sorts

41:51of ideas about like like what's he doing and what's he thinking and then I was thinking how

41:55Oliver Sacks used to spend time imagining experience experiencing life as a bat through

42:02only echolocation he talked about this and I thought and why would he do that right is that

42:08and that's kind of cute he's like delightful old man right he had a 600 pound free weight squat won

42:13the state California of squatting championship but like also like pretending he was a bat.

42:16He's a weird dude. Did methamphetamines, raced motorcycles, you know, like hung out with movie

42:21stars but then also was like a recluse and liked rocks. Okay, that's a weird scientist. I've been

42:27around a lot of those but you know in discussions with people that knew him I mean that exercise of

42:33and like seeing something he thought was cool like a bat you know allowed him to also use theory of

42:40mind to kind of think, what would it be like to have locked in syndrome and only be able to

42:44like blink your eyes to communicate and gave him an incredible compassion and sensitivity for other

42:49people that then he transmuted into the form of like these wonderful books. So for me, fun is

42:57really about doing the things that I do systematically each day. But then when something

43:01excites me, I know that feeling. I know it physically in my body. And to just follow that

43:07trail like a weirdo right like a weirdo just like Barres was a weird and barbara chapman was weird

43:14and like like i think everybody's a little weird if you allow yourself to just see the things that

43:18you think are really cool and there are a bunch of things that i think are really cool that enchant

43:22me that a bunch of other people love too and i know that because it like i see we're all watching

43:28that video or something like that um but i think for me fun is is in the the practice of trying to

43:35stay open to the like the little things um the little things that kids say are always delightful

43:41because they're not filtering through all the bullshit that we filter our self our life

43:45experience through but also just um yeah i like reading and learning exercising i mean i like to

43:52think i'm not a very wooden person but at the same time um i mean i didn't see the barbie movie um

43:59no disrespect to Barbie, I go to movies, I do that kind of thing. I don't know what else is

44:06there to do at some point, you know, what else is there to do? Anyway, I mean, I delight in

44:14certain things, as you now know far too much about, but fun is a relative term.

44:21That was a hard question.

44:23Thank you. Thanks for the pass.

44:29Do you believe time changes due to daylight savings time is worth a potential loss of productivity?

44:35Look, daylight saving times is anti-health. Okay, this is where I'll get like, it's just dumb.

44:41It's just dumb. It's just so dumb. It makes no sense. I mean, the director of the chronobiology

44:48unit at the National Institutes of Mental Health, my good friend, long-time friend, and brilliant

44:52and brilliant scientist, Samer Hattar, will tell you it's a stupid idea. It's anti-biology,

44:58and increased car crashes, increased heart attacks, increased depression. It's just, it's like kids

45:03don't like to wake up early anyway. Parents don't like to wake up early, especially with kids that

45:06don't like to wake up early. It makes no sense. And then there's all these arguments about,

45:11you know, is it really about trying to truncate the late, you know, you want more light in the

45:16evening so there's less crime. Like that's totally unsubstantiated, like it's completely

45:20unsubstantiated. So the daylight savings thing is just stupid. Basically, try and get as much light

45:25in your eyes, ideally from sunlight early in the day. And by the way, if you're worried about

45:29cataract, that's a serious concern. After all, I have an appointment in ophthalmology. You know,

45:34cataract, macular degeneration. But guess what? The chair of ophthalmology from Stanford when he

45:39came on the podcast verified this. When the sun is low in the sky, you're not really at risk of that.

45:45Right? So when the sun is overhead and you're like, you're beaming your eyes, like trying to,

45:48yeah, it's a problem. But we're talking about viewing low solar angle sunlight in the morning

45:53and in the evening. And if there's clouds, do it anyway. In fact, do it longer. And if you can't do

45:57that, look at some artificial light inside. Daylight savings is just stupid.

46:05What happens here is as the night goes on, the amount of GABA in my brain starts to diminish,

46:10and then I just kind of go to short form. We've thought about podcasting in the middle of the

46:13night. That's why when I went on Lex's podcast recently, the more recent one, he did it at

46:18eight o'clock at night and he cried. He made me cry. He didn't cry. He made me cry. I was so tired

46:23and I can't think and then he asked me about my dog and I'm talking about the dog. So you know,

46:27his goal was to get me to cry. We have this friendship, you know. No, he's delightful.

46:34What should I as a 19-year-old college student be doing to maximize the years of neuroplasticity I

46:38have left? I get this question. I'm like, oh man, it's such a great question. Reese, well, I don't,

46:43I'm assuming, yeah, I don't know who you are, Reese, or what you're doing, but you're 19,

46:48so the cool thing is your brain is hyperplastic. Life is a psychedelic experience without psychedelics.

46:56Gosh, people always say, like, if you could go back to your 19-year-old self, what would you do?

47:01And that's a tricky one. There are movies about that, right?

47:05You know, I would definitely worry less. Yeah, I would worry less. I would have more fun.

47:13I would certainly, I started latching on to practices and the understanding of science as a way,

47:22for me it was kind of like my world felt very unstable and for me it brought stability,

47:29but you want to avoid rigidity. So, you know, do you want to be the one 19 year old who's like,

47:34oh, got to get to sleep, you know, got to go back to bed at 8 30 at night. Enjoy life, but I would say

47:41when you're 19, learn how you learn. Learn how to focus. Learn how to rest. Basically,

47:50you can stress and focus as much as you want as long as you can still fall asleep at night and

47:53sleep well and fall back asleep if you wake up. You know, we hear stress is bad, stress is good.

47:59Stress is bad, stress is good. Stress is bad unless you're getting enough sleep, in which case

48:03stress is called learning in life. Now, obviously, don't do anything dangerous. Avoid

48:07psychological and physical danger. But I think as a 19 year old, I mean, my direct advice would be

48:15have some cardiovascular activity you like, have some resistance training activity you like,

48:20develop some sort of self-awareness practice like journaling, could be meditation,

48:25surround yourself with people that you like, avoid people you don't like. I mean, it sounds

48:32so straightforward, but then we can all look into our personal histories and be like, well,

48:35I spent all this time trying to resolve this thing that like clearly you didn't like them.

48:39It's simple.

48:39You didn't like them.

48:41They weren't into cuttlefish or ferrets.

48:42You didn't like them.

48:43Wasn't your kind of person.

48:44Right.

48:44And that's not a box you can check on the dating apps.

48:47They tell me.

48:48Right.

§04Transcript — part 4

48:49The ferret thing.

48:50I think it'd be very, very small subset of people.

48:53I think, you know, the know thyself thing is huge.

48:56Learn to tap into that early feeling of like this feels right.

49:01This doesn't feel right.

49:02Learn to be a bit of a rudder for yourself.

49:06And journal.

49:07I still have stacks of things that I wrote across the years.

49:11Most of it is terrible.

49:12But you will find if you go back that you kind of knew better all along,

49:16even if you didn't do better all along.

49:20That voice in your head, don't do that, do that.

49:24This person's like, everyone else is crazy about this person, but not me.

49:28But this is like, you know, like I don't want to sound sentimental,

49:31but you have to find your heart, right?

49:35Or at least not lose it.

49:36You have to make sure that you're in touch

49:38with that piece of yourself that wasn't judging

49:41and just felt good.

49:42And as long as it's not something that's self-destructive,

49:44I think that's the most important thing.

49:46And then, yeah, have tools and practices in place

49:48because they work.

49:49And when you're 19 and your neuroplasticity

49:52is through the roof,

49:53you can do a lot less and get a lot more.

49:56But don't worry about hitting 25 and it all being over.

49:59Certainly that's not the case.

50:01But you can cram in a lot early on.

50:04I still regret not learning an instrument.

50:06The data on people that learn an instrument even later in life,

50:10but certainly at 19, is that it greatly increases your ability to learn all sorts of things.

50:15So learn an instrument.

50:17How can we transform the American education system to be more effective?

50:20Oh.

50:22So in 10 seconds...

50:23So when I'm in charge...

50:29No, I'm just kidding.

50:30A little while back, I did an interview with a major media outlet, and they were very gracious.

50:35And then they said, like, what's next?

50:37And I was like, I'm going to run for office.

50:39I was just like, you know, I was sort of a, look, it's not out of the question, but frankly, I think that I'm so poorly suited for that.

50:46It's obvious.

50:48I'm so poorly suited for that.

50:49So it wasn't a joke, but it was, you know, I think as I spent some time afterwards, like, oh, I should really go talk to people who do that for a living.

50:55And but I am very interested in potentially informing policy.

51:03If I were to ever be asked, I'd certainly respond.

51:06And my stance on this is, you know, much in the same vein as the podcast, because keep in mind the podcast.

51:12Yes, Lex suggested I start one, but it was really during the the those days of the the deep 2020, 2021 pandemic where, by the way, I wasn't allowed to talk about vaccines.

51:24And so I didn't. And also, I don't have any expertise in it. So I was not well suited to do it.

51:29But I also decided it's a topic that enough people are talking about.

51:32So my response in life and in general, when people say, what about something is I like, well, I've got a lot of opinions about that, but this isn't the venue.

51:40OK. But during the pandemic, I realized there was a lot of circadian disruption, anxiety, stress, a bunch of things happening with visual systems and biological systems that I felt there were tools that that people could.

51:54perhaps benefit from. So I just started putting that information into the world and I was really

51:58surprised, really surprised that people that I knew from the neuroscience community, for instance,

52:04at NIMH or in government positions weren't talking about this stuff. So I just kept doing it.

52:13And I think that it made clear to me that the education system is not one thing. It's tough,

52:22especially when talking about kids, like what to do is a tricky thing, but that the education system,

52:29in my mind, should at least involve some sort of discussion early on about this thing called a brain,

52:37this thing called a body, how they work, how you can do certain things to modulate your stress

52:42level, your sleep, the importance of, not just the importance of sleep and nutrition and avoiding

52:47social isolation and all these important things, but giving people some levers and knobs to

52:53maneuver within themselves and zero-cost tools as a way to do that, that transcend socioeconomic

53:02boundaries, ideally transcend language as well, because we're not just talking about the United

53:07States. And of course, within the United States, there are many different cultures speaking

53:10different languages. And maybe AI will soon allow us to put out the podcast into a bunch of different

53:15languages I think it will. So I think that the education system should start in my

53:22opinion with it with teaching kids how to understand themselves, what to do in

53:27difficult scenarios that's really anchored in in the real pillars of

53:30biology and and psychology and trying to take some of the mystery out of trying

53:35to navigate the tough business of growing up. I mean if you think it's tough being

53:41an adult, which it can be. Certainly, it's really tough growing up, as we all know. And I think that

53:47more tools, more tools, more protocols, more tools, more tools, more protocols, more tools.

53:54But that's obviously a biased opinion. And no one's ever asked me, like, hey,

53:59what should we be teaching kids? But if they ask, you can tell, like, I'm not going to shut up.

54:05So I think that was our last question. Thank you all for coming tonight. I want to

54:10forgive me for going long.

54:14I do want to say

54:15thank you, sincere thank you

54:17for making your way out here,

54:19especially on a weekday night.

54:20Thanks for your hospitality.

54:22My incredible team, I want to thank them.

54:25And certainly, last but not least,

54:28thank you for your interest in science.

54:30Thank you. Thank you so much.

54:31Thank you.
