Summary

This episode delves into the architecture of sleep, breaking down NREM stages (N1, N2, N3) for repair and REM sleep for emotional processing and creativity. It explores how sleep cycles unfold, the impact of ultradian rhythms on daily energy, and the science behind chronotypes. Learn how modern life disrupts our internal clocks and discover practical strategies, like leveraging natural light and understanding your body's unique rhythms, to achieve more restorative sleep.

Episode description

In this episode of the Commune Podcast, Jeff explores the architecture of sleep — the repeating nightly cycles that carry us from light sleep into deep restoration and vivid REM dreaming. He breaks down N1, N2, and N3 sleep, explains why deep sleep is essential for physical repair and immune function, and describes how REM helps us process emotion, creativity, and memory.

Along the way, Jeff highlights the science behind hypnagogia — the imaginative threshold between waking and sleep that inspired minds like Einstein and Dalí — and how understanding these stages can help you wake with more clarity and ease.

Whether you struggle with groggy mornings, restless nights, or inconsistent energy, this episode offers a clear and grounded roadmap for understanding your sleep patterns — and aligning your life with the rhythms your body already knows.

Sleep's Architecture and Stages

Welcome to the Commune Podcast. My name is Jeff Krasnow, and this is part two of my sleep course, The Architecture of Sleep, Building a Rhythm. for rest. So the truth is sleep actually does have an architecture. Every night your brain builds a gothic cathedral of sorts layer by layer. It rises and falls through light sleep, deep sleep, and... REM. So inside that structure are thresholds of creativity. Now, Einstein and Dali often talked about this, that theta wave state.

kind of this liminal place between conscious awareness and sleep. There are chemical cleanups that wash your brain and dreams. that help you process fear and emotion and memory. So in this episode, we're going to walk through all of those stages, the blueprints of your night, and how understanding them can change how you rest and dream and even wake.

This episode is part of my new sleep course on commune. It's a sleeper. Over the next few weeks, we'll go deeper into each layer, exploring how to work with our biology and not against it to finally feel. rested again. So welcome to Sleep Essentials. I'm Jeff Krasnow. When we talk about sleep, it's tempting to think of it as one lengthy blackout.

But sleep isn't a single state. It's more like a structure. Each night your brain builds and rebuilds it in repeating layers, like an architect following blueprints drawn deep into our biology. As some of history's greatest minds were... fascinated by the hidden thresholds of sleep and how they could harvest creative problem solving there. What do they know about sleep that we don't? Scientists classify the different stages of sleep...

based on changing brainwave patterns, eye movements, and muscle tone. Broadly, there are two types of sleep. Non-REM sleep, that's N1, N2, and N3, and REM sleep. Now, stage one begins at the threshold, that liminal space between waking and sleep. You start to let go, muscles twitch, your body feels like it's falling, and your mind begins to slip into a slow rolling theta wave state. This is hypnagogia.

the creative sweet spot, and the first stage of sleep. Einstein used to nap holding steel balls in his hand. Dali did it with a spoon. As they drifted into the edge of sleep state, the objects fell, waking them just in time to capture the dreamlike images floating up from their subconscious. Even science confirms the magic of this threshold. In a 2021 study, people who spent just 15 seconds in N1 were three times more likely to solve a hidden rule math problem than those who...

awake. Think about it for a moment. Just 15 seconds of stage one sleep tripled their creativity in solving a problem. So if you catch me dozing off mid-afternoon with a spoon in my hand, I'm not slacking. I'm problem solving. Einstein style. After a few minutes of N1, then you sink a little deeper into the second stage, N2. Your body begins to settle in.

Temperature begins to drop, heart rate slows, and your eyes stop moving. Stage two lasts about 20 to 30 minutes with your brain working to protect your sleep from the outside world.

NREM Sleep's Protective Mechanisms

On an EEG, you can see two beautiful patterns emerge. Sleep spindles, bursts of rapid electrical activity, like the brain humming to itself. These act like an internal white noise machine helping to block out noises and interruptions so the world doesn't wake you. And in this stage, you'll also experience K-complexes, huge, slow EEG waves that rise and crash like mountains, almost like sentinels standing guard. holding giant do not disturb signs. And then you descend again into stage N3.

Deep or slow wave sleep. This is the most restorative stage and the hardest to wake from. The one where you're truly dead to the world. In this third stage, delta waves dominate. Growth hormone is released, tissues repair, and the immune system strengthens. And the brain's glymphatic system flushes out toxins like... beta amyloid plaques and tau proteins, the same proteins linked to Alzheimer's dementia. It's why kids can sleep through anything. They're swimming in delta waves. But as we age...

this deep stage grows thinner. It's one reason older adults often rise still tired, even after a full night's sleep. And just when the body has done its healing work, then the mind begins its own.

REM Sleep and Its Mysteries

We enter REM sleep, paradoxical sleep, the land of dreams and the subconscious where emotions and memories dance the tango and the mind rehearses life in metaphor. The brain lights up. while the body goes still, paralyzed by Aetonia to protect us from acting out our wild, madcap dreamscapes. Dreams become vivid, story-like, and sometimes strange.

And this is where the mind processes emotions, stitches together memories, and weaves together creativity. During REM, the brain replays fear, danger, and stress like running ancient fire drills. with the stress chemistry dialed down. That's why a painful event often feels softer after you've slept on it.

Sleep Cycles, Naps, Ultradian Rhythms

Of course, sleep isn't a single straight descent into stillness. It's a cycle. We descend from light sleep to deep and rise again through REM. kind of nightly staircase. Each step has its own purpose. One restores the body, another restores the mind. Together, they form the architecture of a healthy night. Here's how we move through these stages repeatedly each night.

In the first cycle, you dive quickly into deep sleep, a long stretch of restoration with only a flicker of dreaming. But as the night unfolds, the balance begins to shift. By the second, third, and fourth cycles, deep sleep shortens while REM expands. The dreams grow longer, stranger. and more elaborate. By dawn you're spending much of each cycle in REM, sometimes dreaming for as long as 45 minutes at a time. This pattern really matters.

Now, if you wake up in the middle of deep sleep, you will still feel groggy, trapped in a fog that scientists call sleep inertia. But wake near the end of a cycle. and you rise more gently, clear, alert, aligned with your own internal rhythm. NASA has studied this grogginess in astronauts and found that it can impair judgment in reaction time for up to an

hour after waking. That's a good reminder not to trust your very first thoughts or texts or emails in the morning. And don't ask me how I know. So how much sleep do we really need? And how do we know if we're getting enough of the right kind? Many people think that eight hours is just the magic number. right? But the truth is that most people thrive on seven and a half to nine hours a night long enough for about five or six complete

sleep cycles. And as we've discussed, when you wake can matter almost as much as how long you sleep. That's why some people turn to smart alarms and wearables designed to wake you just at the right moment, ideally during lighter stages of sleep when it's easier to rise without that heavy fog. Now here's how they work. Apps like Sleep Cycle use your phone's microphone or motion sensors to detect shifts in movement or breathing patterns. Wearable devices like Fitbit, Aura, or Whoop.

go even a step further, tracking your heart rate variability and even body temperature to estimate which stage you're in. When they sense your stirring toward light sleep sometime within a 20 to 30 minute window before you set your alarm, they gently wake you with a smart alarm function. It's pretty clever. And for many, it really does make mornings feel smoother.

But accuracy varies a bit and the data are still best viewed as signals, not absolute truth. These tools and wearables can certainly help you tune in. But just remember, they're just guides and not gurus. And a word of caution. When we fixate on these numbers, we can slide into what doctors called orthosomnia, sleep anxiety caused by trying too hard to sleep well. That sounds like a paradox and leave it to us humans to stress out about our own relaxation, right?

You want to wake up with the sort of subjective feeling of feeling rested and not be totally just reliant on your wearables and devices to tell you that you've got a good night's sleep. So use these tools as a compass. Look for patterns over time instead of perfection each night. If your data shows less REM on workdays and more on weekends, the message isn't to obsess.

Naps, Ultradian Rhythms, Optimal Waking

It's to build more rest into your week. And don't forget the power of short rest. Naps follow the same rhythm as nighttime sleep, just in miniature. Think of naps in three categories. A 10 to 20 minute power nap offers a quick refresh. A 30 to 60 minute nap may cause some grogginess. And the full 90 minute nap, a complete cycle, offers true reset. Now here's something most people don't realize. Your body runs on a roughly 90-minute timer, not just when you're asleep, but all day long.

You can feel it in the waves of focus and fatigue that just move through your day, the crests and troughs, the rise and the dips in energy and focus. And around the world, people have honored these rhythms. in a variety of different ways. A siesta in Spain, a catnap on a Tokyo train, a few quiet minutes with your eyes closed between tasks. These little pauses in our day when focus dips, when we yawn and

reach for coffee. They're not failures of willpower. They're actually part of a deeper rhythm. Hidden beneath our days are quiet, 90-minute waves of energy and rest. Sleep researcher Nathaniel Kleitman first mapped them in the 1950s and called them ultradian rhythms, the same kind of cycles our brains follow. every night while we sleep we've all heard of circadian rhythms circa means about dia means a day so about a day that's a circadian rhythm we're talking about

All tradian rhythms here, these 90-minute cycles. So when cultures build in time for rest, a siesta, a tea break, a quiet lunch, they're not breaking the rhythm. They're actually keeping time with it. Which brings us to this episode's takeaway, the rhythm reset. Here's the idea. So your brain moves through sleep in these 90-minute cycles, these ultradian cycles. Now if you wake up at the end of a cycle, you'll feel clearer and more rested than if you wake up mid-cycle.

Hey, it's Jeff and as an athlete, I've been told my entire life to make sure that I get enough electrolytes. But it's only recently that I have truly understood what electrolytes are and the many essential physiological functions that they fulfill. Okay, so you ready for electrolytes 101? Here we go. When essential minerals like sodium, potassium, chloride, and magnesium dissolve in a fluid...

They form electrolytes, positive or negative ions needed to maintain vital bodily functions. For example, sodium ions are used by the brain to send electrical signals. Hello, electrolytes, through your neurons in order to communicate with other neurons and the cells throughout your body. So electrolytes are key for brain health. Sodium also retains water.

and maintains proper hydration levels and fluid balance in your cells through a process called osmosis. Calcium and potassium are needed for muscle contraction. They facilitate muscle fibers to slide together and move over each other as the muscle shortens and contracts. And magnesium is also required in this process so that the muscle fibers can relax.

after contraction a magnesium is a total other beast it plays a role in protein synthesis sleep and blood sugar balance and hundreds of other functions it's for all these reasons and more that i add element to my water element is a tasty electrolyte drink mix with a thousand milligrams of sodium 200 milligrams of potassium and 60 milligrams of magnesium

And guess what? No sugar. Element is sweetened with stevia, a plant-based sugar substitute that won't spike glucose levels. A 20-ounce serving of many... popular sports drinks that I'm sure you know can contain 36 grams of sugar. It's absurd that those products are marketed as healthy when they contain almost as much sugar as a soda.

Many listeners know that I still play competitive tennis. Before I started using Element, I was prone to fatigue and cramping during long matches due to the loss of sodium. No longer. I'm right there. There, moving like a panther at the end of a grueling three-set match. So right now, Element is offering Commune listeners a free sample pack with any purchase.

Aligning With Your Internal Clock

commune. So when you're deciding your bedtime, count backwards in 90-minute segments, all right? So 90 minutes, that's an hour and a half, and then three hours, and then four and a half hours, and then six hours, and then seven and a half hours, and then nine hours. Those are the ideal sleep segments. So five cycles is about seven and a half hours of sleep. Six cycles is nine hours.

You don't need to be exact. Close enough counts. So each morning, jot down how you feel when you wake. Clear, groggy, somewhere in between. Over a few nights, you'll start to spot your own rhythm. And here's a secret. Try setting your alarm just past those marks to see if your body wakes up naturally. So when it does, get up. Don't hit snooze. Now trust me, I used to be the mayor of Snoozeville. It's not a good office to hold.

Over time, you'll find your own ideal rhythm, not by forcing it, but by noticing when you're already in sync. Additionally, pay attention to your dreams. Do they cluster early in the night or closer to the morning?

that can tell you something about your chronotype, whether your rhythm leans early or late. More on those owls and larks later in this course. And John Steinbeck wrote, It is a common experience that a problem difficult at night is resolved in the morning after the committee of sleep has worked on it. He was certainly right. Each night, a quiet committee, if you will, goes to work, the body repairing, the brain cleansing, the soul dreaming, restoring the architecture of mind and body.

What's broken is rebuilt. What's scattered is made whole. Before there were alarms or work weeks, there was light. The rising and setting sun, the cooling earth, the stillness of night, the original clock. Long before humans or even animals with brains existed, the molecule that helped us fall asleep was already at work.

in our oceans. Scientists have traced melatonin back billions of years to ancient cyanobacteria that used it to protect themselves from sunlight yes the same melatonin in your sleep supplements has been around since the dawn of life now over time that same molecule became a signal of nightfall helping life align with the rhythms of light and dark and today it still does the same thing for us quietly translating daylight into rest

The difference is that now we live by two clocks, the one outside and the one within. And when they drift apart, we feel it. Think of how you feel flying across time zones or even just staying up too late. That's when the clocks clash. So let's take a deeper look at how this internal clock works. Your circadian rhythm is a roughly 24-hour cycle that governs physiological processes from

hormone secretion, to body temperature, to appetite, and of course, sleep. At the center of this timekeeping system is a tiny structure deep in the brain. called the suprachiasmatic nucleus or the SCN. It is the size of a grain of rice and located in the hypothalamus, just where the optic nerve crosses behind your eyes. The light we see is just a small slice of the rainbow, a range of wavelengths measured in nanometers. Shorter waves look blue, longer waves look red.

Our eyes can detect light between about 380 and 740 nanometers, the sweet spot of the visible spectrum. We call this visible light. Ground-level light soothes it. And just think about how we lived for hundreds of thousands of years on the Serengeti. Like, right, we woke up with the sun. We got morning light from the superior field. And at night, we all huddled around.

the fire and told stories and got amber light from the inferior field. And we evolved in relationship to how we lived. So amazing. When those morning wavelengths reach the retina, they send an electrical impulse to the SCN, the suprachiasmatic nucleus. The message is clear. It's daytime!

It's worth noting that most blue light doesn't pass through glass. And this is really important when it comes to protocols, right? A window filters out much of the wavelength that tells your brain that it's morning. So even a few minutes of outdoor light... can do what hours of indoor light can't. The first encounter with daylight suppresses melatonin and triggers a rise in cortisol, the body's daylight hormone. And this begins the daily cycle of energy and alertness. And then...

About 12 to 14 hours later, melatonin begins to pulse again, an echo of sunrise signaling the approach of night. In other words, Morning Light writes the script. for how the night will unfold melatonin the body's messenger of darkness is released by the pineal gland the seat of the soul each evening right on cue if the sunrise signal was clear in the morning

It's how the body remembers the language of light, translating day into night, wakefulness into restoration. At the same time, another player steps forward, cortisol. produced by the adrenal glands that sit just here right above your kidneys. Cortisol is often understood as just the stress hormone.

but it's also your daylight hormone rising with the sun to wake you, to sharpen your focus and mobilize energy. Cortisol is not the enemy. We shouldn't villainize it. It's just that chronic cortisol will disrupt sleep cycle. and a whole lot more. So as the evening comes, the roles reverse. Light fades, cortisol drops. as melatonin begins to rise the body's gentle signal that it's time to rest and this is the beautiful seesaw between

cortisol and melatonin. They move in partnership like the yin and yang, two ends of a teeter-totter. When one lifts, the other lowers. In a healthy rhythm, cortisol peaks in the morning and gradually tapers off, sometimes with a... little bump while melatonin stays low by day and climbs after dark. But here's the twist.

Modern Disruptions and Chronotypes

The SCN isn't the only clock in town. Your liver, your gut, even your skin cells have their own circadian oscillators. They're like an orchestra with the SCN as the conductor. Now, when the conductor and the players are in sync, right, the music is smooth. The composition sounds melodious. When they drift apart, the whole symphony suffers. You get Stravinsky instead of Debussy.

But in modern life, with late night screens, irregular meals, and chronic stress, that balance begins to blur and melatonin lingers low while cortisol stays high and the body forgets what time it is. When the body's clocks fall out of sync, We feel it. We feel it in our energy. We feel it in our mood and we feel it in our focus. You might wake feeling foggy, craving coffee at 3 p.m. or lie awake long after you're tired. It's not weakness.

It's not lack of willpower. It is simply misalignment. Modern life has pulled us far from the light that we evolved with. The sun once told us when it was the right time to eat and wake and rest and dream, but now our cues... come not from the sun. They come from screens, schedules, and stimulants, signals that confuse that delicate rhythm that we just learned about. We've basically outsourced our natural alarm clock to smartphones.

and coffee mugs. So what happens when the modern world rewrites nature's timing? Well, let's look at some of the main culprits. Number one, obvious, right? Artificial light at night, especially light from LEDs. phones and laptops that skew towards that blue light spectrum. These confuse the brain, delaying melatonin release and keeping us up.

Our system is so sensitive that even low light from a bedside lamp can suppress melatonin by 50%. It's one of the simplest, most common ways we tell the body that it's still daytime out. when really it's not. And the second primary culprit, that familiar case of the Mondays. You stay up late on the weekends, sleep in on Sunday morning.

then force an early alarm on Monday. Your biology feels like it's flown across the country, across time zones, without ever leaving home. Scientists dub this social jet lag. the mismatch between your natural rhythm and your social obligations. Late night eating also has a similar effect. When you eat close to bedtime, your liver and your gut stay awake, even if your brain is on schedule. We'll dive deeper into food and sleep later, but suffice it to say, a midnight snack sends mixed signals.

Caffeine doesn't really help either. One study found that drinking coffee even six hours before bed delayed the body's internal evening physiology and cut total sleep by more than an hour. Caffeine's half-life means that latte at 4 p.m. is still in your bloodstream at 10 p.m. So each of these small disruptions, light, timing, food, caffeine may seem harmless on their own, but together they tug the body's clock out of harmony. And when the symphony falls out of sync, so do we.

Have you ever noticed that some people just bounce out of bed at 5 a.m. while others come alive at midnight? That's because each one of us runs on a slightly different schedule known as our chronotype. our natural preference for sleep and wake timing. You've probably heard people say, I'm a night owl or I'm an early bird. That is essentially a chronotype.

Some of us are larks early to bed, early to rise, most alert before noon. Others are owls who hit their stride long after sunset, preferring late nights and slow mornings. But most of us are bears falling somewhere in between, following the rhythm of the sun and the seasons. For some people, these patterns can become really extreme. Delayed sleep.

Phase disorder describes people who cannot fall asleep until three or four in the morning, no matter how hard they try. Advanced sleep phase disorder is just the opposite. Those who start to fade. by 7 or 8 p.m. and wake long before dawn. Now, it's worth noting that our chronotype isn't fixed for life. So we often think of wellness as something external, what we eat, how we move. But inside our bodies is an amazing repair system driven by stem cells.

They're constantly working to renew and restore. But as we age, that repair system doesn't work as well as it used to. But what if there was a way to support it? Well, enter STEM Regen. Founded by stem cell scientist and health pioneer Christian Drapeau, STEM Regen offers unique supplements designed to naturally support

your body's ability to release more stem cells into circulation. More stem cells means more repair, more recovery, and more vitality. It's like giving your body the boost it needs. to stay resilient, rejuvenated, and ready to take on whatever life throws your way.

Teens aren't lazy. They're basically nocturnal mammals. It's biology and maybe a little bit of TikTok. As we move into adulthood and we age, the pendulum often swings back earlier again.

Large-scale studies tracking hundreds of thousands of people around the world show how powerfully genetics, age, and daylight exposure shape these rhythms. Chronotype also carries consequences. forced into early schedules tend to experience more fatigue, metabolic strain, and mood challenges. When we fight our natural clock, performance and health generally suffer. So how do you discover your own chronotype?

Tools like the standard morningness, eveningness questionnaire can help you learn when your body naturally wants to wake and sleep. But the simplest clue is how you feel when you're free from alarms.

Realigning With Natural Rhythms

when you're allowed to rise and sleep on your own time. What happens when our clocks drift away from the sun? When the glow of screens replaces sunrise and our nights stretch long past the dark? You can feel it. That sluggishness in the morning, that restlessness at night, it's the body's quiet protest against misalignment. Scientists call it circadian disruption.

when the timing of your internal systems falls out of sync with the natural day-night cycle, and it has consequences. Chronic misalignment has been linked to higher risks of obesity, diabetes, and depression. just to name a few. We see the strongest effects in shift workers, but even mild social jet lag can throw the body off balance.

The good news is this. Our circadian system is remarkably responsive. It listens to cues, simple signals called zeitgebers or time givers that help reset and re-synchronize your intro. Just 10 to 30 minutes of natural daylight soon after waking, even on a cloudy day, sends a powerful message to your brain. It's time to start the day.

And in winter, especially for those at higher latitudes or for those who wake before dawn, you can actually recreate that signal. A bright light box or a sad lamp generally of about 10,000 lux. can stand in for the missing sun. You got to just set about 12 inches away from it. These lights don't just lift mood. They support the natural rise in cortisol that helps you feel truly awake.

Natural sunlight carries more than color. Its invisible near-infrared light reaches deep into the body, fueling the mitochondria, the tiny engines inside of our cells. There, Light helps spark the enzyme cytochrome C oxidase, which boosts ATP, the body's energy currency, generating subcellular melatonin, our natural antioxidant shield. This serves as the body's daytime repair crew, complementing the pineal melatonin that restores us at night.

This intracellular melatonin is located inside our cells, so it doesn't enter the bloodstream or cause the grogginess that serum melatonin is known for. And here's something extraordinary. When sunlight filters through leaves or reflects off grass or anything green, those near infrared wavelengths are amplified and diffused. In other words,

Sitting in the shade of a tree or walking through greenery doesn't block the sun's benefits. It actually enhances them. Your cells are literally drinking light that's been softened and enriched by the living world around you. Just amazing, right? Light by day protects, darkness by night renews. Screens, on the other hand, are a poor substitute. Their glow may wake your mind, but not in the way that you want.

first thing in the morning. They stimulate thought before the body has actually caught up, lighting the brain's chatter before the clock has found its rhythm. Consistency matters too. Waking at the same time each day anchors your rhythm, giving your body a steady reference point. Yes, even on weekends, I know, which is tragic, but... Sleep scientists are the ultimate party poopers. After sunset, shift towards softer, warmer light. Think amber bulbs, candles, or red lights. Modern echoes of

firelight that tell your body the day is done. Most of our beloved devices now offer night modes or reduced blue light settings. Use them. This amber light signals melatonin to rise and cortisol to taper off, the natural handoff between day and night. Another tip, always eat light at night. Your liver and your gut are on clocks of their own and they rest more easily when digestion winds down before you do.

Morning or early afternoon movement strengthens your rhythm by boosting cortisol and body temperature, the body's natural day mode, but save intense workouts for the earlier part of the day. Researchers at Johns Hopkins recommend finishing exercise at least one to two hours before bed so your core body temperature can fall and sleep.

can arrive. In fact you want to get your core body temperature down to maybe around 97 degrees, much lower than the typical Goldilocks zone of 98.6 that we have during the day. Okay, when we align our light food movement and timing with the sun, our inner rhythms begin to harmonize again. This session's takeaway is called Sunrise Signal. It's a simple... five-day experiment. So each morning get 10 to 30 minutes of outdoor light within an hour of waking and do this for five consecutive days.

So one note here, if it's bright outside and cloudless, you need a little less time. If it's overcast, you need a little bit more time because the lux is lower on an overcast day. so jot down a few notes each evening about your day and how you slept notice your sleep onset how quickly you fall asleep and your daytime energy and vitality now you might be surprised by how fast

your rhythm responds. Rumi wrote, the morning breeze has secrets to tell you. Don't go back to sleep. I'm not exactly a morning person, but even I have to admit, that Rumi's got a point here. Every night when we dim the lights, we tap into an ancient rhythm, one that began in the sea long before we even existed. That same molecule, melatonin, that once protected tiny ocean organisms from sunlight now tells us it's time to rest.

Honoring darkness means remembering our origins, trusting that the body still knows the universal rhythm of night. Step into the light that starts your day. Soften the light that ends it. When your inner clock and the sun follow the same rhythm, life feels in sync again. powers yourselves to the darkness that restores them, this same ancient molecule still keeps time inside of you, light by day, melatonin by night, in a rhythm older than life on land. Until then.
