The Dr. Hyman Show - How To Improve Your Sleep

Episode Date: April 29, 2022

This episode is brought to you by Rupa Health and Athletic Greens.   Inadequate sleep, in terms of both quantity and quality, is a major problem for many of us. Not only does not sleeping well leave us feeling bad, it is also detrimental to our overall health. Poor sleep can lead to everything from mood swings to blood sugar and hormonal imbalances, weight gain, poor memory, and much more.   In today’s episode, I talk with Dr. Andrew Huberman, Dr. Cindy Geyer, and Shawn Stevenson about how to create daily habits to support restful sleep, including how we can best honor our circadian rhythm.    Dr. Andrew Huberman is a McKnight Foundation and Pew Foundation Fellow. He was awarded the Cogan Award in 2017, which is given to the scientist making the largest discoveries in the study of vision. His lab’s most recent work focuses on the influence of vision and respiration on human performance and brain states such as fear and courage. Work from the Huberman Laboratory at the Stanford University School of Medicine has been published in top journals including Nature, Science, and Cell and has been featured inTime, Scientific American, and Discover magazines, the BBC, and other top media outlets.   Dr. Cindy Geyer received her bachelor of science and doctor of medicine degrees, with honors, from the Ohio State University. She completed her residency in internal medicine at Strong Memorial Hospital in Rochester, NY, and is triple board certified in internal medicine, integrative medicine, and lifestyle medicine. She joined The UltraWellness Center in 2021 after practicing and serving as the medical director at Canyon Ranch for 23 years.   Shawn Stevenson is the author of the international bestselling book Sleep Smarter and creator of The Model Health Show, the number-one health podcast in the US, with millions of listener downloads each year.

Coming up on this episode of The Doctor's Pharmacy. We really have this sleep epidemic problem. Getting bright light exposure, ideally from sunlight, within 30 minutes of waking up, is vitally important for getting sleep later that night. Hey everyone, it's Dr. Mark. One of the most important tools I have for helping my patients optimize their health is testing. And that is why I love what Rupa Health is doing. Functional medicine testing

can require placing orders with lots of different labs and it can kind of get really complicated for doctors and their patients to easily access results and keep track of everything. But Rupa Health has totally streamlined that process. Looking at hormones, organic acids, nutrient levels, inflammatory factors, gut bacteria, and so many other internal variables can help us find the most effective path to health and healing. I'm really excited about that now, and I can finally take advantage of these tests without the hassle of the confusion of going through so many multiple labs. Rupa Health is the place for functional medicine practitioners to access more than 2,000 specialty lab tests from over 20 labs like Dutch, Vibrant America, Genova, Great Plains,

and more. It's 90% faster, letting you simplify the process of getting you the functional tests that you need and giving you more time to focus on your patients. This is really a much-needed option in the functional medicine space, and it means better service for you and your patients. You can check it out with a free live demo, with a Q&A, or create an account at rupahealth.com. That's R-U-P-A health dot com. People are always surprised when I tell them that even with a whole foods diet rich in plants, we can still be nutrient deficient. And addressing nutrient deficiencies is one of the lowest hanging fruits for optimizing our health and feeling better at any age. And that is why I'm a huge fan of AG1 from Athletic Greens. Since our soils are so damaged, the plants can't extract the nutrients because there's no living matter anymore.

And we're up against issues like chronic stress and toxicity and sleep deprivation like never before. And our bodies need some extra help getting all the right information to work properly. Now that information comes in the form of vitamins and minerals and phytonutrients and good bacteria, all of which help our cells remember how to efficiently tackle their important jobs. So one of the things I use every day to support my diet is AG1 from Athletic Greens. With just one scoop of AG1, I get 75 high quality vitamins, minerals, whole foods, sourced superfoods, probiotics, adaptogens, and more to support my entire body. Even with a really healthy diet, it's hard to hit

the mark for all our nutrient needs. So I feel better knowing I have some extra help from AG1. Unlike other supplements and powders out there, AG1 is third party tested and made without GMO, nasty chemicals, or artificial anything. It actually tastes great, kind of like a tropical green drink. I like it on its own mixed with water, but it also works really well in most smoothies.

Inadequate sleep quantity and quality is a major problem for so many of us. Not only does it leave us feeling bad, it's also detrimental to our overall health. Poor sleep can lead to everything from mood swings to blood sugar imbalances, hormonal imbalances, weight gain, poor memory, and much more. In today's episode, we feature three conversations from the doctor's pharmacy about the importance of sleep and how to improve it. Dr. Hyman speaks with Andrew

Huberman about habits that set us up for the best sleep, with Dr. Cindy Geyer about overcoming insomnia, and with Shawn Stevenson about how stress impacts sleep quality. Let's dive in. Once you really appreciate how vital sleep is and how great life can be if you're getting good sleep and how terrible it is for our health, both immediate and long-term, if you're not, I think then it creates its own set sleep anxiety. And so one of the things that I've been very active- I've had that for sure. Yeah. To be fair, the body and brain are resilient. If you don't get a good night's

sleep every once in a while, it's fine. You can manage that. Certainly new parents do just fine over time, although it's challenging, but there are a few things that really help with sleep. So in terms of, and there are a lot of causes of insomnia and things. So all the, so they're the basics, like avoiding caffeine in the afternoon, if you're caffeine sensitive, et cetera. But one of them is to start to understand that this state of sleep is not something that you should be able to drop into unless you do a couple of other things properly. And based on the research done in part by my lab, but mainly a guy out at the National Institutes of Mental Health named Samer Hattar. He's the director of their chronobiology unit. He's done these beautiful studies showing that light exposure early in the day, getting bright light exposure, ideally from sunlight within an hour, ideally within 30 minutes of waking up is vitally

important for getting sleep later that night. And the reason is, is it basically once every 24 hours, you're going to have a spike in cortisol. It's non-negotiable. It's built into your genome. It's going to happen. So do people like Arizona sleep better than people in Seattle? Well, well, they do actually.

And a lot of, a lot of people in Seattle need light light boxes. Cause if you're living in an area where you can't get sunlight first thing in the day, feel free to flip on artificial lights, but you want, basically the rule is you want as much bright, ideally natural, but if you can't get natural artificial light would be fine early in the day.

And what that does is it basically times this cortisol spike to wake you up. That spike in cortisol isn't to stress you out. It's to wake you up. And then it sets a timer on your melatonin release. So 14 to 16 hours after your bright light exposure, you're going to get a pulse of melatonin, which is the hormone, of course, that promotes sleepiness and puts you to sleep, independent of any supplementation of melatonin. Light inhibits melatonin through a direct pathway

through the eyes to the brainstem and then up to the pineal. It's a well-established pathway. So the number one thing is get bright light exposure to your eyes so no sunglasses eyeglasses or contacts are fine early in the day how long well it depends on how bright so anywhere from two minutes to 10 minutes ideally you're not looking at your phone during that time ideally it's sunlight but if you wake up before you know flip on a bunch of artificial lights and then get outside once the sunlight is outside taking a walk you're not looking at the sun right you're not looking directly into the sun you don't want to burn your retinas out indirect exposure is fine

but there's a class of neurons called the melanopsin ganglion cells that reset your circadian clock and time things nicely they time the cortisol that time the melatonin so that's the number one thing for i wouldn't just say for sleep, but also for optimizing levels of alertness throughout the day. The other thing is that you really want to avoid bright light between the hours of 11 PM to 4 AM. If you're on a standard schedule, shift workers is totally different. The reason is Sammer's lab and a guy named David Burson at Brown University have shown that bright artificial light of any color, blue blockers or no, if there's bright artificial light, it activates a pathway in the brain involving this brain structure called the habenula.

When I was an undergraduate, actually someone asked in neuroanatomy, what's the habenula do? No one knew. The habenula is involved actually in generating our feelings of disappointment. It suppresses dopamine release for several days afterward. The habenula is involved actually in generating our feelings of disappointment. It suppresses dopamine release for several days afterward. Now, if you have to go to the bathroom or you have to pull an emergency trip to the supermarket or something in the middle of the night, you don't have to worry about crushing your dopamine long term. It's a chronic thing. But you really want to dim the lights in the evening, starting at about 10 p.m.

So you're saying those blue blocker things that doesn't work well the the blue blockers will work but if the lights are bright enough it doesn't matter what wavelength they are and this i is because these melanopsin cells these neurons in the eye they do respond best to blue light but they're very broad spectrum the wavelengths that they will respond to you can shine bright red light on one of these cells and it will signal to the brain, time to wake up. Amazing. So it's really key to just dim things down. And I always say, blue blockers are terrific,

but you don't wanna wear them during the morning and early part of the day because blue light is the optimal stimulus for this wake up signal. So we took, the blue blocker thing is great in principle, but people kind of took it too far. So bright light when you want to be awake and alert and dim light when you want to be asleep. So like, so how many hours before that? Cause you know, people are up on the, on their TVs and their screens and computers and phones.

And yeah, so the subtle things that people can do are to start dimming the lights in the evening, right about the time the sun goes down is when you want to say, Oh, well the sun is going down outside. And if it's overcast, it's getting dark. Well, that's a time to dim the lights in the evening, right about the time the sun goes down is when you want to say, oh, well, the sun is going down outside. And if it's overcast, it's getting dark. Well, that's a time to dim the lights in your home. The other thing is because of the, where these neurons are situated in the eye, overhead lights will activate this wake-up signal much more readily than lights down low.

So the Scandinavians have it right. In the evening, you want desk lamps. Most people aren't going to have floor lighting in their house um desk lamps in early in the day and throughout the day that's when you would want overhead lights so um those two things are going to be very beneficial a lot of bright light overhead light throughout the day ideally from sunlight and then in the evening avoid bright lights of any color any kind between 11 p.m PM and 4 AM. Don't get neurotic about it. But many people find that just making these changes, you don't feel like be off from

like six o'clock at night. No, no, no, no. And there's, there's actually a, the third tool, which is also grounded in really nice work, a paper published in scientific report shows that if you get some sunlight in your eyes in the evening, right about the time of sunset, and if you can't get it from the actual sunset, just go outside. You don't have to see the sun setting. You just need the light, the ambient light, the outdoor light in the morning is sufficient. There's so many photons out there, even on a cloudy day, you'd be amazed. In the evening, if you see or get outside and get some sunlight or you get some light in your eyes, that has an effect of lowering the sensitivity of the, of the retina of the,

the neural part of the eye and provides you a kind of insurance. It offsets a little bit of the late night, bright light exposure. I call it sort of your, your Netflix inoculation, right? It kind of protects you against some of the the ill effects now if someone's schedule is really messed up i mean they're not sleeping they're really screwed up there's a study out of the university of colorado that showed that um this is a little extreme but going camping for two days reset these melatonin and cortisol rhythms for two weeks it's pretty incredible it's really incredible i notice when i go camping or i go out in the wilderness or far away from technology i just sleep way better yeah and we had we had a

storm my house last summer and we got power out for four or five days and we just had candles at night and it was unbelievable i loved it and it felt so good to not have all that bright light at night and to go to sleep and sleep better and deeper yeah you really reset and you mentioned I'm glad you mentioned candlelight candlelight in the evening is fine it actually not to turn people into geeky scientists but there's a great app I have no relationship to it it's but it's completely free it's called a light meter and you can run this experiment you can download the app you go outside on a on an overcast day in Boston in January and press the little button on light meter in the morning,

and it'll show you that even though you don't see the sun, it looks like dense cloud cover, there'll be something like 5,000 lux of light. You'll go inside, you'll point the thing at a really bright artificial light, and it'll say 300 lux. Close the window to the outside, and it reduces it by about 50 fold.

So you don't want to do this through a window or a car window. And then you say, well, wait, you just said that there's very little light intensity coming from artificial lights. Why is it so bad at night? I should be able to turn on every light in the house, and it won't reset.

But the clock and your eye get more sensitive as the day progresses. So you have to control it at both ends and candlelight is fine dim light in the evening is fine but throughout the day you really want to try and get some bright light exposure and for many people that are whose schedules are just really screwed up anchoring to these two or three things of bright light exposure and avoiding bright light in the evening hours between 11 p.m and 4 a.m often not always can really reset people's ability and once you're sleeping well

everything else gets better so that was kind of the the first question you had the other one is that um i'd be remiss if i didn't mention there are things that people can take i'm sure you're familiar with with several of these as well Obviously what we have a doctor right here. So talk to a doctor. Obviously I'm not a physician. I don't, uh, I'm a professor, but, um, so don't prescribe anything, but the three things that have, have made a tremendous difference. I profess, I don't prescribe. That's right. That's what you usually say. Uh, profess lots of things. Um, the three things that I've certainly benefited from, and I know a number of other people have and for which there's really good research

are apigenin, A-P-I-G-E-N-I-N, which is, it's very inexpensive. It's chamomile extract. And it basically turns on a chloride channel mechanism in the brain. It turns off thinking. It's kind of the equivalent of an alcoholic drink. It just off thinking you could still drive on the stuff but it makes people drowsy you drink chamomile tea or you have to take a concentrated um some people get that benefit

from chamomile tea other people like the apigen and the other ones are the magnesium the magnesium and magnesium threonate and by glycinate in particular threonate spelled t-H-R-E-O-N-A-T-E. And biglycinate, I won't spell out, but it's sort of just as it sounds. Those cross the blood brain barrier more readily because you're ingesting this obviously into the gut. And then that magnesium needs to get into the brain. And basically the magnesium seems to act as a precursor to GABA, the inhibitory neurotransmitter. And so for people who have a hard time turning off their thoughts, that can be very beneficial. So there's the kind of light, which is a kind of ancient mechanism by regulating alertness and getting into sleep.

And then there's the modern thing, which is supplements. And there's something sort of in between worth mentioning, which um there's a great tool that was developed by my colleague who's our associate chair of psychiatry at stanford his name is david spiegel he's actually a clinical hypnotist um he's done a lot of work on pain management and even breast cancer outcomes from hypnosis and he's developed a free app that's on apple and on android called reverie r-e-v-e-r-i it's a 15 minute hypnosis that you do in waking which trains the brain to sleep better and i think that a lot of people hear hypnosis and get a little bit freaked out but there are a lot of clinical data

showing that this can help people to learn to turn off their thoughts and to relax and go to sleep and there's some other nice hypnosis scripts in there as well. It's David's voice and he kind of walks you through it. So those are, aside from the supplements, the light and the hypnosis are free resources that I think most everyone could benefit from. If I wake up in the middle of the night, oftentimes I will do one of these hypnosis scripts. And just one other thing about sleep sleep a lot of people wake up at 3 or 4 a.m and can't fall back asleep okay i never understood why that was and then i talked to the folks in the sleep lab at stanford and i talked to the chronic here's probably the reason yeah there's an asymmetry in

this seesaw that we're all equipped with internally which is that we can all push on and stay awake more easily than we can just force ourselves to sleep right that's true right right at some point we fall asleep but if you're waking up at 3 or 4 a.m unless you're drinking too many fluids and that's the reason why chances are you are running out of melatonin at that point it's the levels of melatonin in your blood are dropping and what it means is you stayed up too late and you probably are one of these people that should be going to bed at 8 30 and waking up about 3 30 or 4 a.m and people don't like that answer because they think no but i want to be

the person that goes to bed at 11 and you know there are ways to shift your circadian rhythm that we could talk about but try and go to bed one hour earlier and chances are you will wake up feeling better at 3 or 4 AM. Now it's not exactly a solution, but if you're in an argument with your spouse or something about going to bed at, you know, at one hour or the next, you know, you can leverage biology or cite this discussion. So, wow. So we really have this sleep epidemic problem. And people are struggling with figuring out how to deal with it.

And your lab and you have worked really a lot on how do we navigate the landscape of sleep. Because as we're having this conversation, whatever I ask of you, you keep coming back to sleep, which is fascinating to me as a foundation. And we always think diet is the foundation, exercise foundation, meditation. But sleep is sort of that neglected fourth leg of the table. Well, and it's the thing that we've been encouraged to push through. And I mean, there are some elements,

I mean, that we could get down into the fine science of it. You know, we sleep in 90 minute cycles, ultradian cycles. Better to wake up after six hours than seven, right? You know, for most people for sake of alertness. So waking up at the end of one of these 90 minute cycles, you're going to feel more alert than you would say if you slept into seven hours would mean you were about, you know, you weren't complete through your last ultradian cycle, but sleeping at seven 30 would be even better if you can, you know. So getting the right amount of sleep,

it's a process that you want to master on average. The one occasional all-nighter, you'll be okay. You drink coffee too late, you'll be fine. But on average, you want to be sleeping. Most people, it's going to be anywhere from five to eight hours a night. Naps in the afternoon seem to be okay. The hypnosis script and the other things

will really help people get centered around this i think that the the idea of breaking up one sleep there were these crazy sleep cycles that were promoted the not to be confused with huberman they called it the uberman schedule i just want to be very clear not huberman schedule um there there was a study that came out recently that showed that it's incredibly detrimental to all sorts of inflammatory cytokine markers oh no to try and sleep two hours wake up sleep two hours wake up sleep around the clock there are people that they found they could compress their total sleep time this was a kind of a silicon valley thing like trying to master one you know you you just do have these human bodies you gotta actually yeah you can't conquer the yeah but but i think sleep is vitally important

then i i think um i do think that foundational diet and supplementation and and from the literature i've seen i'd love your thoughts on this that the literature that impresses me the most in terms of diet and the brain and brain states are the studies that look at epa essential fatty acids and the gut microbiome those are the two things that to me it's like it's undeniable i don't understand how anyone nowadays could even question the idea that getting proper lipid intake you know essentially your essentially brain is fat. Yeah. These omega threes are so important. I mean, in a double, several double blind placebo controlled studies that I've read, it appears that getting a thousand milligrams or more per day of EPA.

So not just taking a thousand milligrams of fish oil, but making sure that you're getting above that threshold of a thousand milligrams of EPA from quality sources compares just with similar effect as SSRIs, prescription antidepressants, but without the side effects, right? Which is incredible. And that if you are taking SSRIs, it allows you to take a much lower dose to still be effective. To me, incredible data. And then the other one is that getting ferment, ingesting fermented foods, one or two servings a day. Dr. Justin Marchegiani Sour crop for the brain. Dr. Tim Jackson Yeah. Sour crop for the brain or whatever given culture. Because what I learned, and this is very new and emerging data. There's

a guy at Duke, he's incredible. He was a nutritionist, but then he has PhD in nutrition, excuse me, and now he's a neuroscientist. His name is Diego Borges, not to be confused with the Argentine writer Borges. He's Ecuadorian and he found that there are neurons in our gut of the vagus nerve. So these are neurons that live in the gut endothelium and they sense three things. They fire electrical signals to the dopamine centers of the brain in response to fatty acids, right? When fats are, you know, meats and things are broken down in the fatty acids, amino acids of other kinds,

so from protein and sugar. And so these neurons can easily be tricked into signaling the brain to release more dopamine because dopamine is really the molecule of craving into craving more of whatever activated those neurons. And so if you give these neurons enough EPA or enough amino acids, so protein and essential fatty acids, the dopamine centers of the brain are just firing like clockwork, which is going to enhance mood, motivation, mean dopamine in proper amounts is a beautiful thing too high obviously you don't want but you're not going to get too high people aren't don't get addicted to chicken

breasts but they get addicted to sugar right and i think that's i actually think that's because they're they are these neurons seem to be responding best to particular amino acids they seem to want glutamine of all things. They seem to want the omega-3s. And what's interesting is that even if they numb the taste so that people can't taste sugar, if people ingest sugar, these neurons fire- Dr. Justin Marchegiani Sugar receptors in your gut, right?

Dr. Peter Salgo And they crave more sugar even if they can't taste the sugar. So I always thought that the dopamine release to sweet things was because it tastes so good. But the Borges lab results and some other work on dopamine more generally, from my colleague Anna Lemke at Stanford, shows that dopamine isn't so much about pleasure.

We all, including myself, we're taught it's about pleasure. Dopamine is about craving more of whatever it is triggered dopamine release. Yeah, whether it's heroin or cocaine or sugar or sugar. And so these, and so these neurons that, that trigger dopamine release, they are powerfully affected by,

by these quality omega threes and by amino acids. And then what's really interesting is that they trigger the release of dopamine, but then you say, well, okay, that should be pretty simple. We should, like you said, people don't get addicted to chicken breasts. And I wonder whether or not that's either because omega-3s are too low. So these neurons are not, the full concert of these neurons is inactive. Or it could be that for some reason that the other things that people are ingesting has

messed up these neurons. And so the whole brain body relationship is disrupted and it's, uh, I guess Robert Lustig is his name at UCSF and others are now showing that some of the emulsifiers and foods and other things like that, what they do to the gut endothelium, I never really understood how the gut brain thing worked, but what I realized is, is that these microbiota, they don't care about us. What they do is they, they're trying to find conditions in the gut where the mucus is pH of the mucus is just right. And that if people ingest emulsifiers and sugars, what happens is these neurons and

Borges lab has shown this, that these, that these neurons that are in the gut endothelium and can sense amino acids and can sense essential fatty acids. They actually start to retract their processes into the deeper layers of the gut. gut endothelium and can sense amino acids and can sense essential fatty acids, they actually start to retract their processes into the deeper layers of the gut. In other words, if you ingest the wrong things, pretty soon the neurons in the gut remodel the bad kind of neuroplasticity and you lose your gut brain sensing system. And so it's not just a matter of giving it the right things. It's really about, for many people, it's going to be about repairing this system and, and allowing that this portion of our nervous system to, to grow back. Now, the nice thing about peripheral neurons is that they

grow back. So, and I just gotta, I gotta unpack that because what you said was just so profound right there. Basically you're talking about uncoupling the natural ability of our body to sense its environment and to self-regulate in the right way to create health when we eat processed food that contains ingredients that screw up the gut microbiome or the lining. And all of a sudden that the brain in the gut or whatever you want to call it, the neurons in the gut start to change as a result of the crappy food we're eating and make us less able to seek out and want the foods that are good for us

and tend to make us seek out and want the foods that are bad for us. Exactly. That is a massive brain state shift for me because I never really understood you know the mechanics of how that happens but it's clearly true when people are eating bad foods they want more bad foods and they keep eating more and more of them and there are many reasons for that but the gut story is just fascinating first and foremost we have to recognize that sleep you know you and i

trained in an era where sleep deprivation or how little sleep you could get by on was a badge of honor. Yeah. So we need to shift that internal dialogue that we all have that, oh, if I'm not, if I'm sleeping, I'm wasting my time and I'm not getting my stuff done. So first honor the importance of sleep for your overall health and well-being and even your ability to stick to your intentions around choosing healthy foods and sticking to your exercise plan. Then create a sanctuary that's really conducive for rest and relaxation. Dark, quiet, cool, ideally electronics out of the bedroom or turned off if you can.

Getting rid of all of the light exposures, even your chargers that have that little light. Yeah, like those lights, those red, green lights on different devices. I'm like, that drives me crazy. I had a patient who told me she traveled around with black electrical tape whenever she went to a hotel. And she would put it over all the little light sources in the hotel room. I travel with eye shades because you never know where you're going to be. So those two, quiet, calming. And I think this idea that you go, go, go, go, go, go, hop in bed and turn it off like

a switch, that doesn't work either. So building in a transition to rest and relaxation. If you can do an hour, that's great. And getting off the devices, not watching TV, maybe reading a book or journaling or doing something, taking a bath, stretching in the tub. I mean, there's all kinds of wonderful ways to ease into rest and relaxation. I like the hot Epsom salt bath and lavender drops because the lavender lowers your cortisol,

the magnesium relaxes you, and the sulfur and the Epsom salt helps you detox. That's my favorite as well. And then you go to your cool bedroom and you do your legs up the wall yoga, restorative yoga position, and bingo, you've got your transition to rest and relaxation. So powerful. And alcohol, obviously, is a good practice for people.

Yeah, that's a tough one. That's a tough one. So the rough analogy is this. It's funny, when they asked partners of people with insomnia, how many of them were suggesting that they have a drink to go to sleep? It was about a third of them. So people think alcohol is going to help you sleep and it might make you fall asleep. But then as it clears out of your system, there's an arousal that can exacerbate hypoglycemia. It makes you wake up. It's going to make sleep apnea worse. If you're a woman in midlife, oh boy, it's a bladder irritant. It's a hot flash trigger. So it's really affecting sleep in a lot of ways. The rough equivalent is there's about an hour of sedation followed by an hour of arousal.

Yeah. So if you had a glass of wine at six and you go to bed at 10, it's probably not going to impact your sleep as much as if you have two glasses at eight or like your late dinner last night, if you had a glass or two of wine. I had a beer. Yeah. That has another impact on your sleep. I just noticed it. Actually, I had an aura ring for a That has another impact on your sleep. I just noticed it. Actually, I had an aura ring for a while. I was tracking my sleep. And I noticed whenever I drank, my sleep pattern was so disrupted. Calling of sleep, the depth of sleep, the amount of REM sleep, deep sleep, snoring, you know, all that. It's really interesting. And then caffeine also is another big one, right? Yeah, absolutely. And we're all different in terms of our caffeine metabolism ability.

Some people are really fast metabolizers. I happen to be one of those. But if you're a slow metabolizer, half of your cup of coffee from noon could still be in your system at 9 o'clock at night. And most of the time, we're not thinking back to that new cup of coffee. With food, it's really about quality, quantity, and timing of food. It's all three. Yet another area that's impacted with the health of the gut microbiome is sleep. And data is suggesting that people who eat a wide variety of colorful fruits and vegetables tend to have better sleep quality, whereas a highly processed standard American diet is associated with

more sleep disruptions and less deep sleep. So quality matters. We already touched a little bit on the timing of eating. So eating your calories earlier in the day also helps re-regulate those circadian rhythms. So the clocks in the brain and the clocks in the body that are ideally going to be working in sync with each other, they're influenced by light, by movement, and by food. So when we line all those things up during the day, it's going to help us get the rest that we need at night.

So important. This is such good information. Let's talk about what are the challenges that you see in your clinical practice around women and sleep? And what are the main reasons that you're finding? And some of them aren't expected. And then let's go into how, you know, there would be traditionally approached by conventional medicine.

And then we'll dive into functional medicine. Sure. So I think the first thing is that some common sleep conditions like insomnia and restless legs, they disproportionately affect women and they can have a connection to lifestyle. Sleep apnea, interestingly enough, gets underdiagnosed for women. And there's a lot of reasons which you can dive into it, but some of it has to do with stereotypes on the part of clinicians of thinking about sleep apnea being a man's condition, especially if they're overweight. A big, heavy old guy, right?

Especially putting weight on around the middle, right? But lean women can get sleep apnea too, and it may show up very differently. Yeah. There's also the idea that when we look at times of hormonal fluctuation for women, whether that's before their periods or during pregnancy or the postpartum or the menopause transition, that can also cause an uptick in disrupted sleep. So hormone balance and regulating hormones can play a huge role in improving sleep quality. And finally, you know, disproportionately in the past, caregiving demands

have fallen on the shoulders of women. And I think that really became manifest or evident during the COVID-19 pandemic when you saw a bigger proportion of women than men experiencing an uptick in insomnia, anxiety, and depression. So they're all interconnected. Yeah. So women take on the burden of the families. They often, especially during the perimenopausal years, become the sandwich generation between raising their kids and taking care of their elder parents.

And you're kind of in the middle of of that a little bit toward the tail end of it but you kind of went through that and uh it puts a lot of stress on women also i think there's some there's some unusual causes of sleep that get missed by traditional medicine uh and and and so like if you were a woman and you went to the doctors like i'm having insomnia what are they going to tell you they'll probably tell you to take a sleeping pill. A little Ambien. A little Ambien, yes. A little Valium, right?

And maybe they'll give you an antidepressant, right? Right, right. And of course those come with side effects. They're addictive. They impair cognition. They have all kinds of long-term effects. I mean the benzos or things like Valium or Azepam or Ativan, they may lead to increased cognitive problems like dementia when you get older.

And, you know, we heard all the stories about people wandering around doing stuff they shouldn't do in the middle of the night. It's unfortunate that there are other things, too, that traditional medicine misses that affect sleep. You talked about the big ones, which are the stress and the sleep apnea and the hormonal issues. But there's really more that we know about sleep disruption. And the difference with functional medicine is that we tend to take a detective approach. We don't just stop at the diagnosis.

Insomnia is a symptom. It's not a disease. Right. And so we go, oh, I know it's why you can't sleep. You have insomnia. No, that's just the name of it, silly. That's not the cause. And so we kind of have a different approach. And over the years, there are things we've really uncovered in functional medicine that play a role in sleep that are mostly ignored. And so you share a little bit about it earlier when we were chatting. But what are the kinds of other things

that we see underlying the root causes of insomnia? So if we think about insomnia, about 80% of people who develop chronic insomnia, there's an initial inciting event, but it leads to a stressful event, for example, and there's sleep. Like a death or divorce. Right. Or a transition with the job. And I think the pandemic has contributed to it as well. But then what happens is there's this upregulation of the HPA axis and this chronic overproduction of cortisol, hypothalamic pituitary adrenal axis. So it's the brain's command center that tells the body what to do. Absolutely.

So it's that connection between what our brain is registering as a threat and how that impacts our need to respond to that threat and how that impacts our need to respond to that threat by pumping out these hormones that then in turn keep us ready to deal with a threat that may not be there anymore. So basically, if you're in fight or flight, your job isn't to go take a nap. It is not. It's to stay on alert and wait for the next thing that's going to threaten you. Right. So that activated sympathetic nervous system is huge uh and our culture just does that but absolutely phone is like a dopamine uh you know a pump it's like a dopamine pump that keeps your blood pressure up i mean you know what when people are dying in the intensive care unit

the drug we give them to keep their heart going is dopamine right and that's what great analogy you know and so like it's like at the very end of life like if you can't if everything else epinephrine fail everything you give dopamine because it's so powerful at keeping you awake and alive and so what everything in our life is the sugar the phones all the new like it's just we're constantly in a dopamine barrage. You know, it's funny you said that because I've had people tell me, you know, I wake up at 1.30 every night. I say, well, how do you know it's 1.30?

Because I look at my phone and it says 1.30. And that, again, perpetuates the cycle because then you're thinking, oh, it's 1.30. Oh, crap. I'm awake. I should be asleep. And then it just becomes. Yeah. You know, the best thing I ever did for my sleep issues because i struggle with them as well is um is is putting

my phone and my watch off like just taking everything out and like i'm not knowing what time it is and just letting my body do its thing i think that's brilliant mark and even even sleep trackers for some people it can be a double-edged sword because you're thinking, okay, what's my tracker show me? How well did I sleep last night? When you get a good night's sleep, it's like the world just looks rosy. And when you don't, it looks depressing. Great. And you know, that's an important thing too. If you pay attention to how you feel. So you mentioned the aura ring. People ask me, how good are these trackers for telling you about your sleep?

They don't diagnose a sleep condition. But sometimes you can gain some insights. For you, you gave a great example of this. You found, oh, look at this one. I've had alcohol. My sleep is not as good. My heart rate, variability, everything. And then you pay attention.

Well, how did I feel the day after? Yeah, I was more tired. Yeah, I was more irritable. I was looking for different foods. So I think the more you build that internal awareness of that connection between your sleep and how you feel the next day, that's a win. That's really how you learn to prioritize. Yeah. Yeah. I just take home here is that sleep is the most underappreciated fourth pillar of lifestyle medicine. I agree. It's diet, exercise, stress reduction, and sleep. And it really is important.

And I think I feel like a lot of my health issues in part were driven by lack of sleep. Right. You know, I think as doctors, we were just so trained to overcome our natural instinct to sleep. We have to stay up all night alert seeing patients you either pound the coffee or you just will your way through and i remember i remember like working the er and weird shifts like 11 to 2 in the morning and i'd be like driving home with like tooth holding my eyes up like like this forcing myself to not fall asleep and that just messes with you today more than ever there, there's an epidemic for sure

with sleep deprivation. And we're seeing this show its face in so many different areas. I think the first step is actually understanding the value of sleep. And so for example, real talk, nobody's waking up in the morning like, you know what? I want to look terrible today. Everybody wants to look good. And if we understood just how much our sleep quality affected our body composition, I think it would start to push that conversation forward. So there was a really cool study that was done at university. So sleep and weight are connected. Oh my goodness. University of Chicago did a really fascinating study. So they took folks and they put them on a calorie restricted diet, which is what I was taught to do in university setting, which doesn't necessarily

work by the way, but they put them on this calorie restricted diet. And during one phase of the study, they allow them to get eight and a half hours of sleep. So sufficient sleep, another study, another phase of the study, same people, same exact diet. They're not cutting any more calories. They're not exercising more or less. And now they sleep deprive them. So now they're getting five and a half hours of sleep. They take three hours away. At the end of the study, they compiled all the data. And they found that when folks were getting a sufficient amount of sleep, they lost 55% more body fat just from sleeping.

Yeah. Right? And I didn't say weight. They lost actual fat mass. Not muscle. Which is crazy like how i'm not saying you're doing like eight days a week crossfit right you're just sleeping better and the question for me is immediately like oh my goodness how how is that happening and so it's during sleep that we release

this is crazy melatonin just super glor sleep hormone, which it really isn't that. It's kind of a regulator of your circadian rhythms, period. But it actually is a really profound fat-burning hormone as well. So the Journal of Pineal Research found that melatonin is able to- That's that gland in your head that releases melatonin. It's like-

Pineal gland, correct. Which, that's not the only place. So we'll get back to that in a moment. It's like your third eye gland, basically.'s like pineal gland correct which that's not the only place so we'll get back to that in a moment it's like your third eye gland basically so the pineal gland and it responds to light and you know all the artificial light and the fact it suppresses it it has to have darkness right so the journal pineal research found that melatonin increases your mobilization of something called brown adipose tissue or brown fat. And this is a type of fat that actually burns fat. That increases your metabolism. Yes. And the reason it's brown

versus the white adipose tissue is kind of the stuff we think about when we're trying to get rid of fat. Brown adipose tissue is brown because it's so dense in mitochondria, right? These kind of energy power plants. I know you've talked about many times on the show, but it's such a metabolically active tissue. And so if you're not getting adequate sleep, you're not producing that hormone, nor you get your greatest secretion of human growth hormone during sleep. This is the most, it's also known as the youth hormone in a way. It's the repair hormone. Kids have so much HGH.

This is why they have so much energy. It's muscle sparing. And also it's a big component of you healing and recovering. And so you're missing out on that. And cortisol, that's another one. So if you're sleep deprived, one of the very first things we see is an increase in your cortisol levels. That's the stress hormone. Exactly, exactly. And cortisol has this interesting ability to literally break down the muscle that you're working so hard to build.

It's terrible. Gluconeogenesis, a process called gluconeogenesis. Break down your valuable muscle tissue and turn it into fuel because it's this stressed, hyper, alert, cautious, dangerous state your body thinks you're in because you're sleep deprived. And I can go on and on. I'll share one more. I always say stress is bad because when you have high cortisol, it does everything you

don't want, right? It shrinks your memory center in your brain, causeszheimer's it causes you to lose muscle and gain fat it causes your sex hormones to get screwy uh it has so many horrible effects and it's not worth getting stressed about stuff yeah it doesn't matter you know like stuff there's stuff that does matter that you have to worry about but the truth is most of the things we react to and stress about are just our beliefs or thoughts. They're not really real, right? Yeah, that's a, and I even focused on that as well because a lot of folks have what we call clinically just a lot of inner chatter. You know, the brain is a very vocal and kind of noisy organ, you know?

And so the great thing is a lot of our needs are met, especially if people are listening to this right now. It's like the crazy ant that lives in your head. Right. But we have so many things covered in our lives that our ancestors didn't have to worry about. But the human mind is so expansive, so we can manufacture things to worry about. And that worry can push us. And I often tell people, you know, when people come into my clinic, that you can overeat your whey fat, you can under exercise your whey fat or under move your whey fat, you can under sleep your whey fat, and you can also overstress your whey fat, for sure. It has a huge component for our overall health and our body composition too. So, but I was going to share Stanford University. They found that just one night of sleep deprivation has a dramatic effect on suppressing leptin.

Yeah. Right? And that's that kind of glorified hunger hormone. To make people fall. I mean, I'm sorry, satiation hormone. And ghrelin on the other side has this uptick. And that's that hunger hormone. Yeah.

Right? So just one night. And it makes you crave a ton of carbs. I want to ask you this. I was going to say, I know you've been up late before. Oh, yeah. But I don't know if it's me or if anybody else listening, have you ever been up at like 2 o'clock in the evening, maybe at a party, maybe just kicking back watching TV, and you're

like, you know what? I really want a salad right now. Nope. No. Nope. If that's ever happened, please inform me. I don't get a craving for broccoli. I want salty, sweet, crunchy. Carbs. No. Nope. If that's ever happened, please inform me. I don't get a craving for broccoli. I want salty, sweet, crunchy.

Carbs. Yes. Yes. Because your brain is literally starving for glucose. Just one night of sleep deprivation, we're seeing about a 14% reduction in glucose reach in your brain. Yeah. I know it's true.

I remember working many nights in the emergency room, delivering babies, being up all night. And the next day, all you want to do is eat carbs and sugar. I'd go to McDonald's and get the apple turnovers and the french fries in the middle of the night. That was the only thing that was open in the hospital. So it was only closed between 2 in the morning and 6 in the morning. Otherwise, it was open 20 hours a day.

It was the only thing open in the hospital. Can you believe it? And I would go be sleep-deprived and stay up all night. And I totally craved carbs. Wow. And you did that work on that food. And now what you're made of now and the work that you're doing is just exponential. You see that.

I thought about this the other day. We're putting folks in space on vending machine consciousness, right? Astronaut food. Just imagine if we can get people on really healthy, real food and what we can create as humanity. It's exciting. So what's exciting about your book about sleep is that you break it down. You talk about 21 strategies that are very specific to actually fix your sleep. Yeah.

Because I'm sure many people listening, maybe even half or more, have sleep issues. Whether it's not enough sleep, whether it's disrupted sleep, whether it's poor quality sleep, whether it's more serious things like sleep apnea, people often don't know they have it. So can you walk us through some of the key strategies and what really matters? Sure. So I've been really working to press this into public awareness for about five years now. And this was because seeing people in my office coming in and they're struggling with their blood sugar, for example. And we had about right around 75% success rate with getting folks off lisinopril and

metformins and all this and working along with their doctors. Those are blood sugar and blood pressure pills, right? Yeah. And here's the thing, that 25% of folks who weren't getting those results, ironically, that would really bother me. I know you've probably felt the same thing. Oh, yeah. Yeah. Ironically, kind of keep me up at night. 20%. What are you missing?

And so it took about five years in practice, maybe a little longer before I had the audacity to ask, how was your sleep? And what people would tell me blew my mind. I couldn't believe they're even sitting there. And this is another thing that we know is that folks don't really want to change too much to get the result they want. And I knew that. And so I just dug into the research and I wanted to find clinically proven strategies that people don't have to turn their world upside down. And once I implemented those with the patients I was working with, it's like the floodgates

would come off. The weight would finally come off. Their blood pressure would finally come down. Their symptoms of depression would start to dissolve. And I was just like, this is really something special. I need to tell more people about this. And so eventually it's compiled into these 21 strategies. And for me, again,

some of these things are gonna be a reminder for folks today, but I wanna talk about something that a lot of folks still don't have a big awareness of. And this is the fact that your gut and the health of your microbiome has a huge impact on your sleep quality. So your poop and sleep are connected? What a concept. In a way. Okay, let's dig into that one. Don't do the two together. No, that's not a good thing. That's called accident city. That's going to blow people's mind and even my mind. Tell us how the microbiome and your gut affects your sleep and what you can do about it.

Absolutely. So let's start with a basic component. And I know, again, these are going to be things people have heard about before probably on your show. But let's start with serotonin. Okay. So it's pretty well known. And by the way, there's more serotonin in your gut than there is in your brain. Exactly.

Upwards of 80% to 90% of your body's serotonin is actually located in your gut, produced by your enterochromaffin cells, by the way. Those are special cells in your intestinal lining. Yes. I'm just translating all the big words. See? I like that. We're flipping places because I would do this for you. Here's what's so interesting is that serotonin, we talked about melatonin being important

for our sleep and our circadian rhythm. Serotonin is a precursor or a seed talked about melatonin being important for our sleep and our circadian rhythm. Serotonin is a precursor or a seed to make melatonin. So already right off the bat, your gut environment, these cells in your gut are helping to make this compound that's related to your sleep quality. And with melatonin, this is what I want to liken it to. It's like that manual gear shifter for you to go through your sleep cycles properly and to actually get recovered you need melatonin to be produced and we'll come back to that so that's number one serotonin you can't just take melatonin i'll answer that in a moment

that's tricky okay so well i'll just i'll just tell you so i looked around because some of our colleagues would feel that and this was just a, that if you take supplemental melatonin, it's going to reduce your body's ability to produce it itself. And that's actually, I couldn't find that anywhere. There was no evidence of that. What I did find was taking supplemental melatonin, taking too much or too frequently can downregulate receptor sites for melatonin. So your body can still produce it, but the receptor sites that actually do something with the melatonin can get downregulated. So the key is there, but the lock isn't.

So we do need to be mindful of that and we can come back and talk about that. But here's the biggest probably aha moment, hopefully of this episode, is that it's not just serotonin that's producing the gut. And so check this out and i just came across this i'm gonna share this with you today this was in the world journal of gastroenterology listen to this they found that there's upwards of 400 times more melatonin in

your gut what than in your brain because you talked earlier about the pineal gland that's what i was taught in school it's produced by pineal gland in the story this study found that you can actually have a pinealectomy which is a removal of your pineal gland which i don't recommend by the way don't do that but it's like a frontal lobotomy you don't go there and you don't and you don't actually lose those levels of melatonin that's located in your gut right so you're a gut brain and a brain brain exactly and that that's that's something really important to understand too your gut all right so you're a gut brain and a brain brain exactly and that that's that's something really important to understand too your gut is really it's often referred to as a second brain you know it's we can call it the enteric nervous system there's like 30 neurotransmitters

just like your brain it's like a mass of nerve tissue percent of your immune system and most of the genes in your body as well yeah that vagus nerve. So UCLA researchers found that the vagus nerve, which we thought was just kind of like the brain communicating more, telling the gut what to do. 90% of the communication from those nerve fibers from the vagus nerve to the brain is your belly, your gut telling your brain what to do in many ways. Totally nuts. And the other thing people should know is that when you're stressed, not only is your cortisol high and you lead to more fat accumulation, stores belly fat,

but it actually blocks your cells' ability to burn calories. Because the nerves, the vagus nerve, help you metabolize your food, which is the relaxation nerve. It also has the effect of decreasing absorption of nutrients.

So not only are you not absorbing, It also has the effect of decreasing absorption of nutrients. So not only are you not absorbing, but your metabolism just slows down, which is amazing. It's just because of the nervous connection between your stress nerves and your relaxation nerves and all your gut function. So profound. But this is just getting out of that isolation thinking. This is what I was taught in school as well. It's like, you've got- Well, that's functional medicine. The body's a system.

Yes. Everything is interconnected and it's just beautiful symphony if everything's working well. So Caltech researchers to kind of get to how does this all connect, they discovered that, and this was just, I mean, it's been around for years, but this is more of a recent like, okay, meta-analysis. Now we know that certain bacteria in the gut communicate with cells that produce these sleep-related hormones and neurotransmitters. So your gut cascade, your microbiome has a huge impact on your sleep quality.

And so now the question is, what do we do about it? How do we protect or support our microbiome? And that's one of the things that's going to help to improve your sleep quality. So let's just go through a couple. The biggest thing, in my opinion, is avoiding things that mess it up. So one of those would be eating processed foods. So that crazy amount of sugar has a tendency to feed pathogenic opportunistic bacteria. So that's one thing. Avo avoiding haphazard use of antibiotics they have a place but we shouldn't be using antibiotics every time you get the sniffles right and that's literally what when i was a kid just give them some antibiotics right

we would even like if my mom had some antibiotics you know just totally negligent yeah give them whatever's in the cupboard also um pesticides pesticides, herbicides, rodenticides. Pretty metals. Yeah. These things, side literally means to kill, by the way. Yeah. But these have a pretty, because they're meant to kill small things, guess what your microbiome is made of, you know?

And so. And how many millions and millions of people are taking acid blockers, which also terribly disrupt your gut microbiome. Yeah. We're looking at that the wrong way as well. And so just avoiding those things, but also what I want people to do is support their microbiome by, and this should be just Captain Obvious at this point, and me working at a university for so long as a strength and conditioning coach before I did my clinical work, I worked with people from all over the world and I would ask them about their fermented foods and every culture had something yeah right so whether it was like some kind of

kefir or like yeah pickled whatever right and so making sure that we're getting us at least you know every couple of days get a serving in of some fermented food or beverage gotta eat the kimchi yeah i got a jar in my fridge i love kimchi and my mother-in-law makes it for me and she's from Kenya so they had like fermented a fermented like kind of similar to kombucha like she knew about this like 20 years ago and I'm like what is this weird stuff she's growing yeah yeah in the kitchen is freaking me out she had grabbed like first time I came to visit and they were growing grass you know like it was wheatgrass. But I was like, hey, why's your mom got grass in here?

Did she get it? I didn't know. So anyways. You never got a grass. I didn't know. But that is a big component here is like shifting gears and having a more targeted perspective about supporting that gut microbiome, but also, and this is a really cool takeaway for everybody today, is making sure we're getting in servings of what I call good sleep nutrients every day. Yeah. What is that? Because eating for sleep, nobody really talks about that. So what does that look like?

The first one I'd share, and this one is from the Public Library of Science. And so they found that vitamin C, which we know about vitamin C, we tend to associate it with the immune system, right? It's a powerful antioxidant. But they found that folks in this particular study that were deficient in vitamin C had a tendency towards waking up more frequently. And getting vitamin C levels elevated reversed their symptoms. All right. So that's just one example. So iron is the other one.

If you have a little ferret. Iron is another one. Yeah. Oh, my goodness. That's huge. And especially more other one. If you have a little ferret. Iron is another one. Yeah. Oh, my goodness. That's huge. And especially more so for women, it tends to be. And another one, this was published in the journal Sleep.

This is the big journal. And what they found was calcium. So this goes back to that story that I was told about calcium. It is important important for sure but folks who are deficient in calcium had uh more interrupted sleep patterns as well and so by getting those calcium levels up but how do we go about that i'll just pass it over to you yeah rather than drinking like homogenized glowing dark you know like from a mutant cow like what other sources of calcium calcium do we have oh my god you know it's it's when you look at the data on calcium it actually isn't as great as we thought for bones

but the best absorbability and use is actually from greens like arugula and greens that we can have dark green leafy vegetables also there's some great sources like tahini which is basically ground sesame seeds also different things people might like i like which is sardines with the bones in them and and salmon with the bones in them like canned salmon those are really great to eat because they have a lot of great absorbable calcium exactly calcium is kind of like an end product from this like biological transmutation so bones have a great source of it but you know people say well you don't you need you need milk i'm like well where do you think a cow gets their calcium from and has strong bones? Have you ever seen a cow bone?

They eat grass. Or they should eat grass anyway. This is a really fascinating process. It's kind of like a biological transmutation of sorts where certain things come together to create bone. So you need silica. You need boron. Boron. Vitamin K2.

All of these things come together to make this magic happen so by the way i want to give some sources with vitamin c obviously we know about citrus um fruits like strawberries uh sweet peppers but there are these quote superfoods as well like camu camu berry this might be the highest botanical source of vitamin c uh super tart tangy fruit it's like a amazonian thing uh amla berry acerola cherry those are super super high sources of vitamin c another one and this was this is the last one i'll share there's a whole list uh in sleep smarter so this was a study conducted by university of oxford found that omega-3s can help folks to get deeper more restful sleep all right so it helps with those modulating those rhythms,

which makes sense because it has to do with your brain. Your brain has these gates. You have the blood-brain barrier, but the gate allows in certain VIPs. And it's only like 30 things. And one of those is a megathesis. Although you can have a leaky brain and then you get more trouble.

Oh my goodness. You know about the leaky brain issue? This is like you're already, you're getting into some territory here. is super fascinating stuff right leaky gut leaky brain who knew yeah right who knew so exciting and also there's some um research just came across that the brain kind of has its own nerve um immune system in a way yeah it does it has its own lymphatic system which is like to clean the brain every night. And guess how you do that?

Sleeping. Yep. It's 10 times more active. Yeah. I mean, we know if you don't sleep, you're at much higher risk of Alzheimer's because you can't clear out the garbage and your brain gets toxic.

Yeah. It's fascinating. That's run by the glymphatic system. Yeah. So that's like a little shout out to the glial cells that help to run it. The body is just incredible. So eat plenty good good

sleep nutrients every day magnesium though oh that was the last one actually okay i was like that's the first one i go to my patients this is the big one i was saving the best for last i first learned about the benefits of magnesium probably from you okay this was again like you've been talking about this for like 15 years getting old and um i was like holy crap because it's responsible for so many biochemical oh my god 300 enzymes and yeah and so what that means for people it's just like so magnesium is responsible for these well now we know like over 325 processes what that means is there are 325 things your body can't do or can't do properly when you're deficient on it. Yeah. And by the way, magnesium deficiency affects 48% of Americans. And it's caused by stress.

Yeah. Chronic magnesium deficiency. It's caused by stress. It's caused by coffee, alcohol, and not having enough in our diet, which comes from mostly plant foods, beans and greens, nuts and seeds. Yeah, absolutely. And this is one of the things that we can do something about. I hope you enjoyed today's episode.
