In a world quietly gripped by a growing sleep epidemic—where restless nights, overstimulated minds, and chronic fatigue have become the norm—we turn to one of the leading voices in modern sleep science: Dr. Jade Wu.
With a PhD in clinical psychology from Boston University in collaboration with Harvard Medical School, and as a board-certified behavioral sleep medicine specialist, Dr. Wu has dedicated her career to understanding not just how we sleep—but why we struggle so much to do it well. Her work bridges cutting-edge neuroscience with deeply human, practical solutions, cutting through the noise of an overhyped sleep industry filled with quick fixes and empty promises.
We are truly honored that Dr. Wu took time out of her busy schedule to share her insights with us.
In this conversation, we dive into the heart of today’s sleep crisis: What’s actually driving it? Why are so many high-performing individuals stuck in cycles of exhaustion? And most importantly—what truly works when it comes to restoring a healthy relationship with sleep?
This is not about hacks, supplements, or perfection. It’s about understanding sleep as a living system—and learning how to work with it, not against it.
POH – Frank: Dr. Wu, your journey into sleep science began in a rather unusual place—growing up on the campus of the Chinese Space Agency, where your father worked on sleep studies for astronauts. How did those early experiences influence your fascination with sleep and the human brain?
JADE: I didn’t think much of it as a child. As a 5-year-old, I just figured all scientists measured astronauts’ sleep patterns. But it must have sown some early seed, because at every turn of my schooling and career, I leaned closer to neuroscience, then specifically sleep neuroscience, and eventually clinical sleep science.
Space was the final frontier when I was a kid, but now I think the brain—especially what happens during sleep—is the current final frontier of human knowledge.
POH – Frank: After studying neuroscience and later completing your PhD at Boston University in collaboration with Harvard Medical School, what moment made you realize that helping people with sleep issues would become your life’s work?
JADE: The fun part of doing a clinical PhD is that alongside lab research and dissertation writing, I was also working hands-on with patients in a variety of settings, including a neuropsychology testing clinic and the behavioral medicine unit at the Boston VA.
In every setting, with every type of disorder, I saw sleep problems everywhere—in patients with depression and anxiety, chronic physical illness, dementia, ADHD, PTSD, and more. There just wasn’t a type of medical or psychological condition unrelated to sleep.
By my second or third year of grad school, I just woke up—no pun intended—and knew that sleep would be my focus, with the hope that improving sleep for everyone, even just a little, could raise the water for all boats.
POH – Frank:
Millions of people today report insomnia or poor sleep. From your perspective, what are the biggest reasons so many people are struggling with sleep right now?
JADE: My shortest and most honest answer is: capitalism.
I’m not against free markets or democratic systems, but we often group those positive ideas together with the specific form of capitalism we currently live in—one that prioritizes competition, productivity, and growth above all else.
This system pushes people to tie their identity and self-worth to what they produce. Combined with technology, it means we’re never truly “off.” We’re constantly stimulated, comparing ourselves to others, and chasing the feeling that we need just a little more to be secure.
Now we’re also navigating endless streams of content—including AI-generated content—designed to capture our attention. All of this keeps us overstimulated, anxious, and hypervigilant. It signals to the brain that there are constant threats, making it difficult to feel safe enough to sleep. We’re also more socially isolated, which reduces our sense of safety and belonging—both essential for good sleep.
At the same time, we’re led to believe that we can optimize and control our biology through products and hacks. Ironically, that often disconnects us from our natural instincts and what our bodies truly need.
POH – Frank: Chronic sleep problems can sometimes spiral into anxiety or depression. How do you approach the emotional side of insomnia? And are there long-term health risks associated with consistently poor sleep?
JADE: Insomnia and emotional health fuel each other. People with insomnia are about ten times more likely to experience depression and seventeen times more likely to have anxiety.
Neurologically, poor sleep makes the brain’s emotional alarm system more reactive, while weakening the part of the brain that helps regulate those emotions. Sleep also plays a key role in processing emotions. During REM sleep, the brain helps reduce the emotional intensity of difficult experiences—almost like an overnight therapy session. When that process is disrupted, emotional residue builds up.
That’s why CBT-I—the gold-standard treatment for insomnia—often improves both sleep and mood at the same time. Physically, deep sleep activates the brain’s glymphatic system, which clears waste linked to conditions like Alzheimer’s. Chronic poor sleep is also associated with increased cardiovascular and metabolic risk, including higher chances of diabetes and heart disease. Some biological effects can show up within days, but the real concern is long-term disruption over months and years—not the occasional bad night.
It’s also important to distinguish between sleep deprivation—when you don’t have enough opportunity to sleep—and insomnia, where you have the opportunity but can’t sleep well. These are very different conditions.
POH – Frank: First of all, with your book Hello Sleep, you talk about shifting from fixing sleep to building a relationship with it. What does that look like for a very performance-driven person who is constantly in “go-go-go” mode? How can they practically build that relationship day by day?
JADE: Yes, I think the most important piece here is actually a philosophical shift, combined with some practical elements.
The big idea is that we shouldn’t treat sleep like a junky car that just gets us from point A to point B. We shouldn’t exploit sleep as a resource to be used up. Instead, we need to be in a mutually respectful and nurturing relationship with it. Because if we just take, take, take from sleep, we’re not putting anything back into the reservoir.
I see this a lot with high-performing individuals—they treat sleep as this annoying thing they have to do in order to perform. Or they try to engineer it so they can optimize and exploit it even more. But that approach isn’t sustainable. Things change, and if you don’t invest in the system, it will eventually fail. Sleep is a living system—you have to adapt to it rather than fight it. So for high performers especially, it’s important to nurture sleep, invest in it, stay curious about it, and let it inform your behavior—rather than imposing rigid rules or trying to control it.
POH – Frank: Listening to you, it almost sounds like preparing for a relationship—like a pre-wedding phase with sleep. But unfortunately, many people are already in a kind of fight—or even a “divorce settlement”—with their sleep.
If someone is completely out of sync—late nights, early wake-ups, inconsistent patterns—and wants to rebuild a more peaceful relationship with sleep, but feels almost tortured by it… what would be the very first step?
JADE: Assuming we’re talking mostly about insomnia—trouble falling asleep, staying asleep, unpredictable patterns, or unrefreshing sleep—the very first step is to stabilize your morning rise time. Hold your wake-up time steady, and let the rest flex.
Both parts are important. You can’t force a rigid schedule like “sleep at 10, wake at 6,” because falling asleep is not something you can control. There’s no on-off switch—it’s an involuntary process. At the same time, you also can’t give it zero structure and just let it drift across the day with random naps. The brain needs guidance—but also freedom.
So: anchor your day with the same wake-up time every morning. Set an alarm and stick to it. Then, go to bed only when you feel sleepy—not before. Even if that means it’s 2AM. To support this process in the beginning, you can allow a short nap—around 30 minutes—in the early afternoon. This helps you function safely while your system resets.
Over time, your brain will begin to regulate itself—you’ll naturally feel sleepy at a more consistent time in the evening and wake up more steadily in the morning.
POH – Frank: There are also these famous 3AM wake-up calls—you know, cortisol spikes—where people fall asleep and are lucky to even get there, but then it’s almost like an internal clock that wakes them up at the exact same time.
So what do you do when you have these wake-ups—you’re sweating, you’re up at night—what is the best way to handle that?
JADE: Yeah, the 3AM wake-up is not necessarily a cortisol spike. Everybody wakes up during the night many times—we just don’t remember most of those moments. But one very common experience is waking up around 2 or 3AM.
That’s not because of anxiety or a cortisol spike. It’s actually built into a natural, healthy night of sleep.
Humans naturally experience biphasic sleep. Before industrial times, we used to sleep in two phases: one longer chunk in the first half of the night, then wake up for a couple of hours—doing chores, talking, baking bread—and then return for a second sleep. The two parts of sleep are very different. The first half is deep-sleep heavy—this is when the body does most of its physical restoration. The second half is more REM and light sleep, where emotional processing and dreaming happen.
There is even a natural “intermission” between these phases. The challenge today is that we’ve been conditioned to believe sleep should be one uninterrupted 8-hour block. But that’s not necessarily how human sleep works. So we don’t need to fear the 3AM wake-up. What we need to be careful about is our reaction—waking up, becoming frustrated or anxious—because that is what keeps us awake and damages our relationship with sleep.
POH – Frank: So there’s also this myth of the perfect 8-hour sleep. And of course, depending on age and activity, that varies from person to person. But isn’t there a danger if someone consistently only sleeps 2–3 hours a night over months? There’s this idea that sleep cleanses the brain, balances chemistry—so can chronic lack of sleep actually damage the brain?
JADE: That’s a really good question, and there are a few layers to it. First, there is a very tiny fraction of people who genuinely only need 2–3 hours of sleep—but that’s extremely rare, maybe one in a million. The vast majority of us need more.
The key distinction here is between sleep deprivation and insomnia. Sleep deprivation is when you don’t have the opportunity to sleep—external factors prevent it. For example, someone working multiple jobs, someone in the military on a mission, or extreme situations like imprisonment. In those cases, the body is truly not getting enough sleep. Insomnia is different. It’s when you have the opportunity to sleep, but it feels like you’re not able to.
Why does this matter? Because in true sleep deprivation, if you put someone in a quiet, dark room, they will fall asleep immediately—the brain is desperate for sleep.
But with insomnia, people often feel like they only sleep 2–3 hours, even when that’s not actually the case. There are a couple of reasons for that. First, people tend to remember their worst and most recent nights, and forget the nights where they slept more or dozed off during the day.
Second, people with insomnia often don’t perceive light sleep as sleep. Stage 2 sleep—which makes up about half of a normal night—can feel like being awake. We see this in lab studies: brain scans clearly show the person is asleep, but when we wake them, they say, “I was just lying there awake.” So it’s not that they’re imagining it—it’s that their experience of sleep is different.
POH – Frank: Is this considered something like lucid dreaming?
JADE: No, this is not lucid dreaming. Lucid dreaming is when you are in a dream, but you are aware that you’re dreaming, and you can control what happens. What I’m describing is called sleep state misperception—basically misperceiving the state of sleep that you’re in. The good thing is, once insomnia is treated, people stop misperceiving their sleep. A big part of chronic insomnia—week after week, year after year—is that the brain becomes hypervigilant. It’s almost like developing a phobia of being awake.
If you have a phobia of spiders and you’re in an old wooden shed, you’ll start seeing spiders everywhere—every shadow, every movement. It’s the same with sleep. If your brain is afraid of being awake at night, it becomes overly alert to any sign of wakefulness, and it starts mistaking actual sleep for being awake. If you string together all these brief awakenings or misperceived moments, it can feel like you were awake for hours—when in reality, you were asleep most of that time.
That’s why someone who is truly sleep-deprived is very different from someone with insomnia who feels like they only slept 2–3 hours.
POH – Frank: But is it possible that someone with severe insomnia becomes almost afraid to fall asleep? Like there’s a fear of not waking up, or not getting enough sleep, and it creates this vicious loop? How do you treat people like that? Is it possible to treat them without medication—just with mindset or behavioral approaches?
JADE: It’s absolutely possible to treat these people. I’ve personally treated hundreds without medication, and even helped people come off medications they’ve been on for decades. And it’s not just positive thinking—it’s a structured approach with a few key components.
The first is behavioral change—resetting the physiology of sleep.
People with insomnia often stretch their sleep window—they go to bed early and wake up late trying to “catch” more sleep. But this actually dilutes sleep quality. It’s like having a small amount of pizza dough and stretching it too thin—you end up with holes. So instead, we shorten the time in bed. That forces the brain to consolidate sleep and improve quality. We lead with quality—and once quality improves, quantity follows naturally.
The second component is reducing conditioned arousal. Over time, the bed becomes associated with frustration, anxiety, and struggle. So we work to break that association. If you’re not sleeping, you get out of bed and do something calm elsewhere. You stop trying so hard to sleep—because that effort often backfires. You “drop the rope” and stop the tug-of-war with sleep.
The third component is addressing unhelpful beliefs about sleep. For example, people often believe they’re only sleeping 2–3 hours, but when tracked more carefully, it’s usually more than that. So we help them reframe their perception, decatastrophize the situation, and build a more flexible, realistic relationship with sleep.
As that anxiety decreases, sleep naturally improves.
POH – Frank: Is there, in general, a difference between men and women when it comes to sleep? Are men overlooking specific factors—like emotional processing, stress patterns, or hormonal cycles? Can you say that women have fundamentally different sleep issues than men?
JADE: In terms of insomnia, women are about one and a half times more likely to experience it than men.
One reason is hormonal disruption. Starting at puberty, girls begin to experience more insomnia than boys due to monthly hormonal fluctuations. Then, later in life—pregnancy, postpartum, perimenopause, menopause—these phases introduce major hormonal changes that can directly and indirectly disrupt sleep.
Another factor is related to gender roles. Traditionally speaking, women tend to carry more of the mental and emotional load—planning, organizing, managing relationships, and thinking about daily logistics. These are the kinds of thoughts that are harder to switch off at night.
Men’s work, historically, has been more compartmentalized—clocking in and out—whereas women’s responsibilities often run 24/7. That’s why women are more prone to racing thoughts and difficulty “shutting down” at night.
On the other hand, men are more likely to have sleep apnea—roughly two to three times more likely. However, women are often underdiagnosed because research and diagnostic criteria have traditionally been centered around male symptoms. So women’s more subtle symptoms are often missed or attributed to something else, like menopause.
POH – Frank: Can you explain a bit more what sleep apnea actually is?
JADE: Sleep apnea is a breathing disorder that occurs during sleep. It means that your airway becomes blocked for at least 10 seconds—and often longer—so you’re not getting enough oxygen while CO₂ builds up. When the brain detects this, it forcefully wakes you up so you can breathe again. These awakenings are usually too brief to remember, but they can happen many times throughout the night. Mild sleep apnea means this happens 5 to 15 times per hour. Severe sleep apnea can mean more than 30 times per hour—so essentially every couple of minutes, breathing is disrupted.
This leads to highly fragmented sleep. People never reach deep, restorative sleep, and they wake up feeling exhausted—often with symptoms like snoring, dry mouth, headaches, and daytime fatigue.
POH – Frank: There’s also this belief—especially among men—that you need to completely exhaust yourself physically during the day in order to sleep well. Is that a myth, or is there some truth to it?
JADE: It’s partly true. We do need physical activity to sleep well, because sleep is essentially recovery from what happens during the day. If nothing happens—if you’re inactive all day—then there’s less need for recovery, and you may not feel as sleepy.
If you do a strong workout, especially strength training, your body needs to rebuild muscle tissue. That process happens during sleep—especially deep sleep—so you may actually get more and better-quality sleep. However, there’s another side to this. If you’re constantly “on”—always busy, never resting mentally or physically—your brain interprets that as being under constant threat, like you’re being chased by a tiger.
In that state, your body won’t want to relax into sleep. So yes, we need activity—but we also need real periods of rest during the day.
POH – Frank: Coming back to hormones—there’s often a strong focus on hormones in women’s health, but less so for men. How do things like testosterone, cortisol, or aging impact male sleep? And do men go through similar hormonal shifts that affect sleep, like women do during menopause?
JADE: Hormones definitely play a role, although I’m not an endocrinology expert—especially when it comes to testosterone specifically. In general, as people age, they tend to sleep a bit less and need slightly less sleep. Sleep architecture also changes—we get less deep sleep and more light sleep, with more frequent awakenings.
But that’s not necessarily a problem. Our bodies simply have different demands at different life stages. When we’re younger, we’re growing, repairing, and more physically active—so we need more deep sleep. As we age, those demands decrease. What becomes more important is rhythm.
For example, cortisol should naturally be higher during the day—helping us stay alert—and lower at night. But many people today have disrupted patterns: cortisol that is too high at night, too low during the day, or inconsistent overall. This can be caused by chronic stress, lack of daylight exposure, irregular schedules, or lifestyle factors. So often, what we think of as a “sleep problem” is actually a body clock problem. When we realign our rhythms—light exposure, activity, metabolism, and hormones—sleep improves naturally, and so does overall health.
POH – Frank: One quick thing about this whole sleep optimization industry. If you start having sleep problems and go on Instagram, you get completely bombarded—tips, supplements, magnesium, devices, this and that. What’s your general take on this? Sleep has become a multi-billion-dollar industry. Are there things that really work, or is this largely an exploitation of people who are struggling?
JADE: I have strong feelings about this. There are products and tools that can be helpful—if they’re evidence-based, matched to the right problem, and used appropriately. But honestly, the vast majority of what you see on TikTok and Instagram around “sleep optimization” is fluff. At best, it’s harmless but useless. At worst, it increases anxiety or leads people to take things that backfire or are even harmful.
The challenge is that people treat sleep as a lifestyle issue—and it is, to some extent—but it’s also a medical issue. If someone has diabetes, they go see a doctor. They don’t rely on TikTok hacks. But with sleep, people often do exactly that, which makes it a very tricky space. There are some technologies and supplements that can help in certain situations—but it’s highly individual and case-by-case.
POH – Frank: What’s your approach to alternative healing modalities—like acupuncture, Chinese medicine, breathwork, or somatic therapies for improving sleep? Do you believe in them?
JADE: There is actually solid evidence supporting several of these approaches. Practices like Tai Chi, acupuncture, meditation, relaxation training, and similar modalities have good research backing them for improving sleep and insomnia. However, they typically don’t have strong evidence to show they can cure insomnia on their own.
For some people, they might be enough—maybe a few acupuncture sessions can reset the system. But for many, a more structured approach is needed. The gold standard treatment is cognitive behavioral therapy for insomnia—CBT-I. That includes the behavioral changes to reset sleep physiology, and the cognitive work to rebuild a healthier relationship with sleep.
POH – Frank: Last but not least—if you had one piece of advice for someone who is currently struggling with sleep, frustrated, overthinking—what can they do tonight?
JANE: Don’t go to bed until you’re sleepy.
And if you’re in bed and can’t fall asleep—or you wake up and can’t fall back asleep—don’t try to force it. Get up, or at least sit up, and do something enjoyable. The goal isn’t that the activity will make you sleepy. The goal is to stop struggling with sleep. The more you try to chase sleep, the more it runs away. So don’t hunt it—just allow it.
Think of it like this: you don’t sit at the dinner table for hours trying to force yourself to feel hungry. You eat when you’re hungry. Sleep works the same way. Trust that your body knows how to sleep. Let it happen naturally. And keep a steady wake-up time in the morning.
That alone can make a huge difference. And if needed, you can build from there with more structured support—but the biggest shift is simply: stop trying so hard to sleep.
POH – Frank: Thank you so much—this was wonderful. Truly.
