You slept for eight hours, but you wake up feeling like you barely slept at all. The problem may not be how long you were in bed—it may be what happened during those eight hours.
In this episode of The Health Pulse, we explore sleep architecture, the carefully organized sequence of brain states your body cycles through each night, and why timing, continuity, and sleep-stage distribution can matter alongside total sleep duration.
We begin with the two major systems governing sleep: homeostatic sleep pressure and the circadian rhythm. Adenosine accumulates during waking hours and contributes to the drive to sleep, while your internal circadian clock helps determine when your brain and body are biologically prepared for sleep and wakefulness. Together, these systems help organize the repeating cycles that structure the night.
Then we travel through the major stages of NREM and REM sleep.
We explain the transition into lighter sleep and why hypnic jerks can suddenly make you feel as though you're falling. In stage N2, characteristic sleep spindles and K-complexes appear as the brain works to maintain sleep while participating in processes involved in learning and memory.
Next comes N3 slow-wave sleep, the deepest stage of NREM sleep. This is when slow synchronized brain activity dominates and important aspects of physical restoration occur, with growth hormone secretion strongly associated with early-night slow-wave sleep. It's also the stage from which waking can produce intense sleep inertia, and where parasomnias such as sleepwalking and night terrors commonly arise.
Then the brain enters REM sleep. Brain activity becomes more wake-like, vivid dreaming becomes common, breathing grows more variable, and skeletal muscles enter REM atonia—temporarily suppressing most movement while the brain processes information and emotional experiences.
But these stages aren't distributed evenly throughout the night.
Deep slow-wave sleep is concentrated earlier, while REM periods become progressively longer toward morning. That means shortening the final portion of your sleep may disproportionately reduce REM-rich sleep, even when your total time in bed doesn't seem dramatically different.
We also examine what happens when sleep becomes fragmented. Repeated awakenings can disrupt normal sleep architecture even when someone technically spends seven or eight hours in bed. Over time, inadequate or disrupted sleep can influence cortisol rhythms, appetite regulation, food choices, glucose metabolism, and insulin sensitivity, connecting sleep quality directly with metabolic health.
Finally, we look at sleep trackers. Wearables can be useful for observing long-term trends in sleep duration, timing, and consistency, but consumer devices are not equivalent to polysomnography for determining precise sleep stages. Obsessing over imperfect sleep scores can even contribute to orthosomnia, where anxiety about optimizing sleep begins interfering with sleep itself.
And sometimes persistent fatigue deserves a deeper investigation. Depending on symptoms and clinical context, tests such as a CBC, ferritin, and iron studies may help uncover contributors such as iron deficiency, while snoring, witnessed breathing pauses, morning headaches, or excessive daytime sleepiness may warrant evaluation for obstructive sleep apnea.
Eight hours is a useful number. But restorative sleep is more than a stopwatch—it is an organized biological process your brain has to complete.

Let's dive in.
SPEAKER_02
What if I told you that your brain burns almost as much energy when you are totally unconscious as it does when you're wide awake?
SPEAKER_01
I mean, it's pretty wild to think about. People usually assume sleep is just, you know, a biological off-switch.
SPEAKER_02
Right. But today we're gonna look at the massive, complex architectural build happening inside your skull every single night. Like, have you ever slept for eight straight hours, done everything right, but you wake up feeling like you literally ran a marathon in your sleep?
SPEAKER_01
Oh, absolutely.
SPEAKER_02
You drag yourself out of bed, you look at the clock, and you just think, how is it possible that I am this exhausted? Well, today we are going to explain exactly why that happens.
SPEAKER_01
Yeah, and it's it's one of the most frustrating experiences we all go through. It completely contradicts this ingrained idea we have that sleep is just a matter of logging enough hours. Yeah. We tend to think of sleep as a passive state. You know, you close your eyes, time passes, you wake up. But physiologically, the reality is the exact opposite.
SPEAKER_02
Okay, so let's unpack this. We are doing a deep dive into a really comprehensive report from Quick Lab Mobile. It's titled The Stages of Sleep: What Happens to Your Body Each Night.
SPEAKER_01
It's a great report.
SPEAKER_02
And what blew my mind right away is that judging your rest solely by the number of hours you get is entirely missing the point. Our mission today is to decode this hidden, highly active world of your sleeping brain.
SPEAKER_01
Exactly.
SPEAKER_02
If we really want to understand why we wake up tired, we have to look at the massive invisible systems running the show
Aaron Powell Right. Because to understand the big picture, you have to look at the two interacting systems that govern this entire nightly process. First, you have what's called sleep pressure. Okay. Think about what happens when your cells are working all day, burning energy. They leave behind a chemical byproduct called adenosine.
SPEAKER_02
Adenosine, right.
SPEAKER_01
Yeah. And as the day goes on, adenosine builds up in your brain, docking into specific receptors. And that creates this intense biological pressure to shut down.
SPEAKER_02
It's sort of like sand piling up on a scale. Every hour you're awake, another grain of adenosine drops onto the scale. And eventually that weight becomes so heavy, it just forces your brain's off switch down.
SPEAKER_01
Aaron Powell That is a perfect way to visualize it. And the second system working alongside that scale is your circadian clock. Trevor Burrus, Jr.
SPEAKER_02
Which is our internal rhythm, right?
SPEAKER_01
Aaron Ross Powell Exactly. It's deeply influenced by light and dark, and it dictates when your brain is actually prepared to sleep or be awake. Together, these two systems don't just tell you when to fall asleep, they actively dictate the structural progression of your sleep stages across the entire night.
SPEAKER_02
Aaron Powell Wow. Okay. So if our metabolic drive and internal clocks are setting the stage, what actually happens the exact moment you give in
to that heavy adenosine pressure and close your eyes? The research breaks this down into cycles, right?
SPEAKER_01
Aaron Ross Powell Yes, the entire night is basically a repeating loop. A typical adult sleep cycle takes roughly 90 minutes.
SPEAKER_02
Aaron Powell Just 90 minutes.
SPEAKER_01
Yeah. It varies a bit from person to person, but generally we go through about four to six of these 90-minute cycles over the course of a full night. Aaron Powell Okay. And that cycle kicks off with the transition into
Aaron Powell Right. And cycle one starts with stage N1. I'm looking at the breakdown of this first stage, and it says our brain waves actually change shape here.
SPEAKER_01
Aaron Ross Powell They do. Yeah.
SPEAKER_02
Aaron Ross Powell We go from fast alpha activity to slower theta waves, but what does that actually mean physically? What is a brain wave changing shape?
SPEAKER_01
Aaron Ross Powell That's a great question. A brain wave is essentially the electrical signature of millions of your neurons communicating.
SPEAKER_02
Okay.
SPEAKER_01
And when you're awake and alert, those neurons are firing rapidly, and honestly, somewhat chaotically, because you're processing a million different things at once.
SPEAKER_02
Aaron Powell That's the alpha activity?
SPEAKER_01
Right. It looks like fast, frantic scribbles on a monitor. But as you enter N1, your neurons start to sink up and fire at a slower, more rhythmic pace. Those are the theta waves.
SPEAKER_02
Aaron Powell It's like chaotic, crowded rooms suddenly starting to chant in unison.
SPEAKER_01
Aaron Ross Powell Exactly. N1 is the bridge. Your awareness of the room fades, your muscles relax, and your eye movements slow down.
SPEAKER_02
Aaron Ross Powell But it's really light sleep, right?
SPEAKER_01
Aaron Ross Powell Very light. It's so light that if someone said your name right then, you'd wake up and probably swear you weren't even asleep yet.
SPEAKER_02
Aaron Powell Which explains so much about my partner falling asleep on the couch during a movie and claiming they were just, you know, resting their eyes. Oh, definitely. But N1 is also where one of the weirdest bodily glitches happens: hypnic jerks.
SPEAKER_01
Oh, yeah.
SPEAKER_02
That sudden, terrifying sensation of falling that makes your whole body spasm just as you're drifting off. Why does our body do that?
SPEAKER_01
Aaron Powell It is such a bizarre phenomenon. Biologically, as your muscles deeply relax during that N1 transition, your brain can sometimes misinterpret that sudden lack of tension as literal free fall.
SPEAKER_02
Seriously? It thinks we're falling.
SPEAKER_01
Yeah. It panics and sends a massive electrical jolt to your limbs to catch yourself. It's completely
harmless, but it's a very intense start to the night.
SPEAKER_02
So we survive the hypnic jerk, and within minutes the brain moves deeper. This brings us into stage N2.
SPEAKER_01
Right.
SPEAKER_02
And apparently this takes up the largest chunk of our entire night. This is considered stable sleep. The heart rate slows down, breathing becomes regular, core body temperature actually drops. But the brain is not powering down at all, is it?
SPEAKER_01
Not even close. The electrical activity here gets fascinating. You see two very specific patterns emerge here: sleep spindles and K-complexes.
SPEAKER_02
Okay, sleep spindles. What are those?
SPEAKER_01
Aaron Ross Powell, they are these brief, intense bursts of rapid brain activity. They're generated by the thalamus, which acts as your brain's sensory relay station.
SPEAKER_02
Like a switchboard operator.
SPEAKER_01
Exactly. The thalamus is talking to the cerebral cortex, which is the outer layer of the brain where complex thinking happens.
SPEAKER_02
Aaron Powell So what are the switchboard and the cortex actually doing during these bursts?
SPEAKER_01
They are doing two vital things. First, they're actively blocking external noise from waking you up. The thalamus literally decides to stop forwarding sensory signals to the cortex.
Nicolette
Oh wow.
SPEAKER_01
Second, they are transferring the information you learn that day from short-term memory storage into long-term memory storage.
SPEAKER_02
That is amazing. And what about the K complexes? The research notes these are large, massive electrical spikes that can happen spontaneously or in response to sounds in your bedroom.
SPEAKER_01
Right. They allow the brain to evaluate incoming information from your environment without actually waking you up.
SPEAKER_02
I love this concept. It's like your brain is a computer that went into sleep mode, but it's secretly running a background virus scan.
SPEAKER_01
That's a great way to put it.
SPEAKER_02
So if a K complex lets the brain evaluate a sound like a car driving by or a floorboard creaking and decide it's not a threat, does that mean our brain is basically standing guard while we sleep?
SPEAKER_01
What's fascinating here is that that is exactly what it's doing. N2 is perfectly bridging light rest with the deeper stages to come.
Nicolette
Yeah.
SPEAKER_01
It really shows the brain's incredible ability to multitask. It is simultaneously maintaining your unconsciousness, processing the memories you made that day, and actively monitoring the external environment to keep you safe.
SPEAKER_02
It basically secures the perimeter. Exactly. And once the brain has secured the environment in N2 and feels safe, it dives into the absolute heavy lifting of physical
Aaron Powell The heavy lifter, absolutely. Stage N3 is the deepest stage of NREM sleep. It's often called slow wave sleep.
SPEAKER_02
Aaron Powell Because of the brain waves.
SPEAKER_01
Aaron Powell Right. Going back to our brainwave discussion, the brain is now dominated by large, incredibly low frequency delta waves.
SPEAKER_02
Aaron Powell So if the awake brain is a chaotic room and N1 is a rhythmic chant, N3 delta waves must be like massive slow stadium wave of neurons firing together.
SPEAKER_01
Aaron Powell That's a brilliant visual. Millions of neurons firing in deep, slow, synchronized pulses. And this is where physical recovery really happens.
SPEAKER_02
Aaron Powell What kind of recovery?
SPEAKER_01
Well, your blood pressure falls to its lowest point, and your body is entirely relaxed. Crucially, the secretion of human growth hormone is heavily concentrated right here in N3.
SPEAKER_02
Aaron Powell So this is literally when we heal. Tissues are repairing, muscle is being built, and the immune system is being regulated and strengthened.
SPEAKER_01
It is the ultimate restorative state for the physical body. And because it's so deep, it is extremely difficult to wake someone up from M3.
SPEAKER_02
I can imagine.
SPEAKER_01
If you do manage to wake them, they experience what's clinically called sleep inertia.
SPEAKER_02
Oh man. That severe disorienting grogginess where you don't know what year it is, what city you're in, or who you are. I know that feeling intimately.
SPEAKER_01
We all do. Your brain was in such a deep state of slow wave synchronization that abruptly forcing it back to fast waking alpha waves is a massive biological shock.
SPEAKER_02
This also clears up a huge misconception for me. When we think of sleepwalking or night terrors or confusional arousals, we usually assume the person is acting out a dream.
SPEAKER_01
Right. That's the common assumption.
SPEAKER_02
But it turns out those actually emerge from this deep slow wave N3 stage, completely separate from the dreaming stage.
SPEAKER_01
Precisely. That's why someone who sleepwalks typically has absolutely no memory of the event the next morning. Wow. They were in the deepest state of slow wave physical sleep, completely detached from the conscious awareness or visual storytelling
But eventually the 90-minute cycle has to move into that dream state, which is REM or rapid eye movement sleep.
SPEAKER_01
Yes. And here's where things get physiologically bizarre.
SPEAKER_02
Aaron Ross Powell Yeah, your eyes are darting around under your eyelids, your heart rate and breathing become highly irregular, and vivid, complex dreams take over. In fact, brain activity increases so much that on an EEG, it looks almost exactly like you're awake.
SPEAKER_01
It does. It's a wildly active state. But to keep us safe while the brain is this active, it triggers a mechanism called muscle atonia.
SPEAKER_02
Aaron Powell Which is what exactly?
SPEAKER_01
Muscle litonia is a temporary, complete suppression of activity in most of your skeletal muscles. It's essentially a temporary paralysis.
SPEAKER_02
Wait, really?
SPEAKER_01
Yeah. Your vital muscles, like your diaphragm for breathing, they keep working perfectly. But your voluntary muscles, your arms, legs, neck, are locked down.
SPEAKER_02
Aaron Powell Wait, hold on. I have to wrap my head around this paradox.
SPEAKER_01
Okay.
SPEAKER_02
If the whole point of sleep is rest and recovery, why is my brain working just as hard during a dream as it is right now while we're talking? Why burn all that massive energy just to create a hallucination while simultaneously having to paralyze the physical body? That seems incredibly counterintuitive.
SPEAKER_01
Aaron Powell It seems like a paradox until you realize that NREM and REM contribute cooperatively, but to completely different domains of your survival. Okay. How so? As we established, N3 physically rebuilds the body, tissues, immune function, growth hormones. REM, on the other hand, is processing the mind. It plays a vital role in memory consolidation, complex learning, and emotional processing.
SPEAKER_02
Aaron Ross Powell So it's sorting through all the chaotic data from the day.
SPEAKER_01
Exactly. The brain has to be highly active to sift through, file, and integrate all the emotional and cognitive experiences you had while you were awake. Trevor Burrus, Jr.
SPEAKER_02
Makes sense.
SPEAKER_01
It evaluates what's important enough to keep and what to discard. It takes immense energy to do that. And the dreams you experience are essentially a byproduct of that intense neural networking.
SPEAKER_02
Wow. So M3 fixes the hardware, and REM updates the software.
SPEAKER_01
Aaron Powell That's the perfect analogy.
SPEAKER_02
Aaron Powell But knowing what these individual stages do is only half the battle. Because what becomes glaringly obvious in the research is that the real secret to feeling rested lies in how these stages stack up over time and how easily that delicate
structure can be destroyed. Let's talk about the architecture of sleep.
SPEAKER_01
Sleep architecture refers to the changing composition of these stages throughout the night. It is not an even spread. Right. N3, that deep physical repair stage, is heavily front-loaded. It is concentrated primarily in the earlier sleep cycles, right after you fall asleep, when that homeostatic sleep pressure, the adenosine we talked about, is at its absolute peak.
SPEAKER_02
Aaron Powell And REM is the exact opposite. REM periods start out very short early in the night, maybe just a few minutes, but they become progressively longer and more frequent toward the morning. REM is backloaded.
SPEAKER_01
Exactly. And this distribution has massive practical implications for your daily life.
Nicolette
Yeah.
SPEAKER_01
Because the brain has such an overwhelming biological drive for slow wave sleep. If you go to bed unusually late but keep your same wake time, your brain will still preferentially preserve that N3 deep sleep in those early hours.
SPEAKER_02
But if you wake up artificially early, say cutting your sleep short by an hour or two with a blaring alarm clock, you disproportionately rob yourself of REM sleep, right? Precisely. Because that is when your REM cycles are hitting their longest duration.
SPEAKER_01
Aaron Ross Powell You are quite literally chopping off the most important part of your brain's software update, which explains why you might feel physically okay, but emotionally volatile or mentally foggy all day.
SPEAKER_02
Aaron Powell But it's not just about when you sleep, it's
about continuity. It's about fragmentation. Yes. The research describes fragmentation as disruptions that cause micro arousals. We're talking about things like obstructive sleep apnea, where the airway physically narrows and you stop breathing for a moment, forcing the brain to wake up just enough to gasp for air.
SPEAKER_01
Very common.
SPEAKER_02
Or chronic pain or even just environmental noise. And the crazy part is you might not even consciously remember waking up.
SPEAKER_01
You can have dozens, even hundreds of these micro arousals in a single night.
SPEAKER_02
It's like trying to run a washing machine. Imagine you load up a washing machine to clean your clothes, but someone keeps walking by and opening the lid every 20 minutes. Right. The cycle stops, it resets to the beginning, and your clothes never actually get clean, even if the machine was technically powered on for eight solid hours.
SPEAKER_01
If we connect this to the bigger picture, this is the exact reason why time in bed and restorative sleep are completely different concepts.
SPEAKER_02
Oh yeah.
SPEAKER_01
This fragmentation is what leaves you exhausted after eight hours. Your body never got to progress continuously through the necessary sequence of N1, N2, N3 and REM. It just kept resetting the washing machine.
SPEAKER_02
And alcohol is a notorious culprit here. We all have this cultural idea of a nightcap to help us sleep. And sure, it might shorten the time it takes to initially fall asleep because it's a depressant.
Nicolette
True.
SPEAKER_02
But later in the night, as it metabolizes, it severely fragments your sleep and completely destroys your REM cycles. You are basically opening the lid of your own washing machine.
the architecture. And if a fragmented night means you're missing out on continuous N3N REM, the consequences go far beyond just feeling a little sleepy or needing an extra cup of coffee.
SPEAKER_02
Aaron Powell This is where things get genuinely alarming. It triggers a massive metabolic chain reaction.
SPEAKER_01
Aaron Powell It does.
SPEAKER_02
If your sleep architecture is dismantled, it fundamentally alters how your body processes energy and food the very next day. Trevor Burrus How did they do that?
SPEAKER_01
Aaron Powell They just stopped them from getting that deep delta wave sleep by playing tones that kept them in light sleep. After only three nights of this, their insulin sensitivity declined by approximately 25%.
SPEAKER_02
Wait, a 25% drop in insulin sensitivity in just three days?
SPEAKER_01
Yes.
SPEAKER_02
Why? How does a lack of brain waves change how a cell absorbs sugar?
SPEAKER_01
Aaron Ross Powell It comes down to the nervous system. Deep N3 sleep is when your body clears out stress hormones like cortisol and allows your nervous system to fully relax.
SPEAKER_02
Okay.
SPEAKER_01
Without that deep sleep, your nervous system remains in a low-grade fight or flight state. Cortisol stays elevated. And high cortisol tells your cells to block insulin and hoard sugar in the bloodstream for immediate emergency energy. Oh, wow. Aaron Ross Powell So your body suddenly requires a much greater insulin response from the pancreas just to manage a standard everyday meal.
SPEAKER_02
So if I have a disrupted sleep cycle missing my N3, it literally changes the biological way my body handles the sugar in a donut the very next morning.
SPEAKER_01
Aaron Powell Yes. And it profoundly changes your desire to eat that donut in the first place.
SPEAKER_02
Aaron Powell Right, because appetite regulation gets completely scrambled. It's not just a simplistic shift in your hunger hormones, though that happens too. Right. Sleep loss actively increases your brain's reward responses to highly palatable, calorie-dense foods. Your higher level decision-making cortex is exhausted, and your primal reward centers are screaming for a quick energy fix to keep you awake.
SPEAKER_01
And when you combine that amplified drive for junk food with a 25% drop in insulin sensitivity, you have a recipe for a metabolic disaster.
SPEAKER_02
Aaron Powell Yeah, that's a vicious bidirectional cycle.
SPEAKER_01
Trevor Burrus Exactly. Poor sleep worsens your metabolic health and promotes weight gain. But then metabolic dysfunction, like obesity, strongly increases the risk of obstructive sleep apnea, excess tissue actually compressing the airway at night.
SPEAKER_02
Which then further destroys your sleep architecture through hundreds of micro-arousals.
SPEAKER_01
It's a terrifying loop.
SPEAKER_02
You cannot out-diet chronic sleep fragmentation.
SPEAKER_01
You really can't.
SPEAKER_02
Sleep must be viewed as an equal pillar to nutrition and exercise in any metabolic health strategy. Absolutely. If the body doesn't receive consistent, continuous sleep to regulate hormones and clear stress, the perfect diet and exercise routine won't function optimally.
SPEAKER_01
No, it won't.
SPEAKER_02
So if our metabolic health depends entirely on getting
this exact, uninterrupted ratio of N3 deep sleep to REM sleep, how on earth are we supposed to know if we're actually achieving it? That exact anxiety is why everyone is suddenly sleeping with a smartwatch on. Right.
SPEAKER_01
The trackers.
SPEAKER_02
But our attempts to measure this architecture might actually be backfiring.
SPEAKER_01
Aaron Powell We have to be very, very careful with consumer wearables. They have made sleep visible, which is fantastic for general awareness, but they only estimate your sleep stages.
SPEAKER_02
Just an estimate.
SPEAKER_01
Yeah. They use complex algorithms based on your movement, your heart rate variability, and sometimes blood oxygen, but they do not and mathematically cannot measure your actual brain waves.
SPEAKER_02
Aaron Powell Because the gold standard for that is polysomnography or PSG in a clinical sleep lab.
SPEAKER_01
Exactly.
SPEAKER_02
That's the only way to actually measure the EEG electrical activity in your brain, your true eye movements, and your muscle atonia.
SPEAKER_01
Aaron Powell So if your smartwatch tells you that you got very little deep sleep on a Tuesday night, it is making an algorithmic guess. It is not a clinical diagnosis. But people fixate on these numbers as if they are absolute truth.
SPEAKER_02
It is the ultimate modern irony. We buy a sleep tracker to sleep better, and chasing that perfect sleep score gives us so much anxiety that we develop what the research calls orthosomnia.
SPEAKER_01
Orthosomnia, yes.
SPEAKER_02
It's a literal anxiety about sleep that puts you in a state of hyper-arousal, making it even harder to fall asleep. You're staring at the ceiling, stressed out that your watch is going to yell at you tomorrow morning.
SPEAKER_01
It is incredibly counterproductive. The most useful way to approach wearable data is to look at long-term macroscopic trends.
SPEAKER_02
Okay.
SPEAKER_01
Is your overall sleep schedule wildly irregular? Are you consistently spending less time in bed overall? Don't fixate on a single night's bad stage score.
SPEAKER_02
So if your smartwatch is just guessing and it's driving you crazy, how do you actually find
This is where the research shifts away from tech gadgets and back to biology. Because sometimes feeling tired has nothing to do with your sleep architecture and everything to do with what's running through your veins.
SPEAKER_01
Exactly. Laboratory testing serves a crucial role here, not by measuring sleep stages, but by identifying underlying medical factors. For example, Quick Lab Mobile in Miami offers at-home laboratory testing to look at these exact markers.
SPEAKER_02
Oh, nice.
SPEAKER_01
They can check a CBC and ferritin levels for iron deficiency.
SPEAKER_02
And how does iron affect sleep?
SPEAKER_01
Well, iron is a critical building block for dopamine in the brain, and dopamine regulates your movement. If your iron is extremely low, it frequently causes restless leg syndrome, or you have this irresistible urge to move your legs at night, which massively fragments your sleep. And most importantly, if you have persistent symptoms like loud snoring, witnessed breathing pauses, morning headaches, or excessive daytime sleepiness, you need a clinical evaluation with a real doctor for something like sleep apnea. You don't just need a newer smartwatch algorithm.
by asking why eight hours in bed doesn't always equal feeling rested. And the answer is that sleep is a wildly active architectural masterpiece.
SPEAKER_01
Beautifully said.
SPEAKER_02
So for everyone listening, that is the biggest takeaway today. Stop judging your rest by duration alone and start thinking about the continuity of your sleep.
SPEAKER_01
And I'll leave you with one final thing to mull over.
SPEAKER_02
Okay.
SPEAKER_01
If things like alcohol, stress, early alarm clocks, and untreated sleep apnea are systematically dismantling our delicate sleep architecture night after night, year after year, how much of what we just culturally accept as normal aging or inevitable metabolic decline is actually just the biological result of decades of unremembered, fragmented sleep.
SPEAKER_02
Wow. Think about that tonight as you close your eyes, feel the adenosine take over and drift down into stage N1.
