It’s nearly 4 a.m., and Bhavin R. Sheth is awake at home. He’s noodling over a problem that’s been bothering him for days. “I’m really not the best advocate for sleep right now,” says the University of Houston associate professor of electrical and computer engineering. Sheth has been interested in the brain and sleep for decades. His recent work has centered on how to better capture what happens across the body when we doze, but lately he isn’t sleeping. He laughs at the irony of the sleep-obsessed having been up half the night.
This happens — the body wants to rest but the mind has other ideas — and not just to professors and scientists.
Most adults are kept awake occasionally or often by unsettled work matters, unresolved family conflicts, troublesome relationships, financial concerns, health worries, existential angst, creeping anxieties about anything and everything. Sheth has developed a way to manage this for himself when the effect of sleepless nights starts to add up. It works sometimes; other times, he gets out of bed and goes for a walk.
Even for those who study it, sleep is a fickle mistress. Just don’t tell that to the sleepmaxxers — the biohackers and wellness enthusiasts obsessively optimizing every nighttime variable in pursuit of the perfect slumber.
Hacking the Night Shift
Among social media influencers, the sleepmaxxing trend is wide awake. Millions of posts on TikTok offer hacks for improving or maximizing sleep. They document increasingly elaborate nighttime routines, and creators showcase blue-light–blocking glasses, magnesium powders, mouth tape, nasal strips, weighted blankets and more. They calibrate their bedrooms like dreamtime incubators. It’s sleep hygiene on steroids for the purpose of health and beauty.
In one widely circulated genre of posts, sleepmaxxers walk viewers through a “perfect night,” layering interventions: no screens after 8 p.m., warm bath (or cold shower!), red-light lamp, sleep supplements, thermostat check, a precisely timed wind-down routine. The supposed payoff arrives in the morning not only as looking and feeling more refreshed but also as a score from a wearable device. An Oura Ring, Fitbit or Apple Watch presents “proof” that these techniques work.
Sleep score of an enviable 92? Maybe you’re ready for the Sleep Olympics. Pitiful 61? Metaphorically speaking, you can go back to bed. At its core, sleepmaxxing reflects a familiar modern logic: If something can be measured, it can be improved. If it can be improved, it can be optimized.
And if it can be optimized, can we live longer?
For years, the dominant attitude toward sleep ran in the opposite direction. “I’ll sleep when I’m dead” was a mantra for rock-and-roll living. Sleep was something to cut back on in service of ambition and endurance. Sleepmaxxing flips the more-is-more script and feeds into another obsession with a longer tail: longevity hacking. The game may have changed from getting more in the moment to getting more in the long run, but the underlying assumption that sleep can be bent to our will and data will help us do that remains the same.
Sheth pushes back. Better data, he says, does not necessarily lead to better sleep or a longer life.
No Way to Bank Sleep
“Better data just gives you better data,” Sheth says. He spent the last few years developing gold-standard sleep tracking using only heart data from a single-lead electrocardiogram. The product of the work, done alongside University of Southern California researchers Laurent Itti and project lead Adam Jones, is open-source software that could make professional-grade sleep studies with minimal intervention accessible to millions at home.
Such studies could mean more — and more accurate — sleep data, because they would be more convenient and less expensive than traditional sleep studies conducted overnight in a lab, where patients are fitted with multiple electrodes to monitor brain activity, eye movement, muscle tone and breathing.
Because the setup is cumbersome, with wires attached across the scalp and body, and the surroundings are unfamiliar, a clinical environment can alter how a person sleeps. The result is highly detailed data, but it’s not always a perfect reflection of how sleep unfolds at home. Sheth’s work could bridge the gap between consumer wearables, which offer convenience but limited precision, and traditional lab studies.

However and wherever the data is collected, sleep resists simplification, says UH Associate Professor Bhavin Sheth. It’s not a single variable to be dialed up or down, nor is it a discrete outcome that can be captured in a cool score.
Regardless of how and where the data is collected, Sheth says, sleep resists simplification. It’s not a single variable to be dialed up or down, nor is it a discrete outcome that can be captured in a cool score.
Sleep’s a complex process shaped by multiple dimensions — duration, depth, timing, physiology, environment — some measurable, others not yet fully understood or measurable, he says. Data also doesn’t change the fundamental fact that where human bodies are concerned, biology sets the rules.
Sometimes those rules oppose the language surrounding sleep, increasingly framed in economic terms as something you can “bank” on the weekends or “budget” across a busy week. You can’t sleep longer on the weekend in order to sleep shorter during the workweek, but it does appear that you can “invest” in sleep for long-term health by building better sleep habits to reap health benefits now and later.
Undeniable Ripple Effects
Among those today-and-tomorrow benefits is greater emotional regulation. That is exactly where researchers at the UH Sleep and Anxiety Center of Houston come in. They have synthesized more than 50 years of research on sleep deprivation and mood.
It turns out that even when sleep is only mildly deficient, there are measurable negative changes in how we react to everyday events. The center’s findings, published by the American Psychological Association, confirm that sleep loss results in fewer positive emotions — joy, happiness and contentment. In the study, it increased anxiety symptoms such as a rapid heart rate and increased worrying among participants.
That connection helps clarify how sleep intersects with long-term health. Sleep supports the body over time, but its influence isn’t transactional — more sleep in, more years out. Rather, it’s systemic. It shapes mood, stress response and emotional regulation, all of which are linked to broader health outcomes over time.
Sleep is not a form of biological capital. It can’t be accumulated and invested over time. There’s no science that backs up that claim.
Sheth, however, points to a broader historical context that complicates the idea. Compared to people living 150 years ago, he says, modern populations sleep differently and under less natural conditions. Artificial light, screens everywhere and irregular schedules have altered the way we rest, yet life expectancy has increased by several decades over that same period.
The comparison is imperfect, he acknowledges, shaped by advances in medicine and public health. Still, it underscores a key point: Sleep alone does not determine lifespan. It does, however, create many ripple effects.
Research also shows sleep impacts cardiovascular health, metabolic function and immune activity. Sleep impacts the brain, and the brain impacts the gut — it’s all interconnected — but it can’t be said that sleep is a form of biological capital, Sheth says. It can’t be accumulated and invested over time. There’s no science that backs up that claim.
The Bottom Line
Sleep alone does not determine lifespan. Think of it as a potential amplifier rather than a determinant.
The relationship between sleep and a very long life is generally modest, Sheth says. Large-scale population research shows that although getting adequate sleep can ward off an early death, that doesn’t equate to more sleep, longer life. In fact, it could be the opposite.
In a study of more than 1 million adults, those who slept between six and seven hours a night had lower mortality rates than those who regularly slept eight or more hours per night. The findings, drawn from data collected by researchers at University of California, San Diego School of Medicine and the American Cancer Society, challenged the long-standing assumption that eight hours is the universal benchmark for optimal health.
In fact, participants who reported sleeping eight hours were more likely to die during the study period than those who slept seven, even after accounting for factors such as age, health status and lifestyle. It’s not clear why, but researchers cautioned that longer sleep may be a marker of underlying physical or mental health issues.
Where does that leave us? With the irrefutable basics.
For all the enthusiasm around sleep optimization, the fundamentals haven’t really changed. What seems to matter is not hitting an exact number but maintaining a pattern that allows the body to cycle through sleep stages in a sustained way. Regular sleep and wake times; exposure to light at the right points in the day; and a cool, calm environment are the best ways to support that.
These recommendations aren’t new, and they’re not especially optimized. They are, in many ways, optimization resistant — less about a perfect score than about a process the body was designed to do when given the right time and conditions.
