Sleepmaxxing: does it work?

What is sleepmaxxing?

Sleepmaxxing is a social-media name for stacking habits, products and gadgets in the hope of engineering the perfect night’s sleep. Anita Shelgikar, a sleep physician at the University of Michigan, described it to CNN in March 2025 as “a collection of activities, products or ‘hacks’ used simultaneously to optimize sleep quality and quantity”. The name is borrowed from looksmaxxing, another online trend, as the Guardian noted the same month.

What goes into the stack varies from video to video: tape over the mouth, nasal dilators, magnesium and melatonin, red-light glasses, two kiwis before bed, a cool and completely dark room, and a tracker to score the result. Some of it is as much about how you look in the morning as how you slept. By August 2025, AFP was describing tens of millions of posts on TikTok and X, and influencers selling mouth tape, drink powders and melatonin gummies to go with them.

At the far end, AFP found clips of people hanging by the neck from ropes or belts as an insomnia remedy, a practice experts warned about after a Chinese state broadcaster linked at least one death in China to a similar routine. Nobody should try that one.

Underneath the excess is something sensible. After years in which people boasted of getting by on very little sleep, “focusing on sleep is a good thing”, as a Rutgers professor of medicine told CNN. The useful question is which parts of the stack do anything.

Which sleepmaxxing hacks actually work?

Here are the usual ones, each held up to the best evidence we could find. Most have a page of their own, linked in the last column; the table gives the short version. “Worth trying?” is a judgement for an ordinary sleeper who is curious, not advice for a sleep disorder.

Several of these were tested only in particular groups — older adults, psychiatric patients, people with mild sleep apnoea — and a result in one group need not hold in another.

Which sleepmaxxing tips are worth keeping?

The parts with the best evidence are the least photogenic. Asked about the trend in 2025, the sleep experts that CNN and the Guardian spoke to gave much the same list:

• a regular wake time and bedtime, weekends included;
• daylight early in the day;
• a cool, dark, quiet bedroom;
• no caffeine or alcohol in the several hours before bed;
• less screen time and bright light before bed, and a calm wind-down you can repeat;
• naps of no more than 30 minutes.

“The key is having a consistent routine and consistent sleep-wake schedule,” Shelgikar told CNN. None of it needs buying, and most of it works on the body clock and on the pressure to sleep that builds through the day, rather than on the night itself. The bedtime routine guide goes through it properly, and how to fall asleep covers the time in bed.

Can sleepmaxxing make your sleep worse?

It can, and this is the part the videos leave out. Sleep is one of the few things that trying makes worse. The psychologist Colin Espie’s account of how insomnia takes hold runs from paying attention to sleep, to intending it, to effort — and rests on the observation that sleep is “a relatively automatic process” which “may be inhibited, by focused attention and by direct attempts to control its expression” (Espie and colleagues, 2006). A ten-step routine, a supplement stack and a score every morning are all focused attention.

Trackers add a number to fail. In 2017, sleep clinicians described patients who came to them convinced they had a sleep problem because of what their tracker showed — “a perfectionistic quest for the ideal sleep”, which they called orthosomnia (Baron and colleagues, 2017).

“The more we try to control sleep with hacks or rigid routines, the more vigilant and stressed we become — paradoxically making sleep harder,” Kathryn Pinkham, a UK-based insomnia specialist, told AFP in 2025. Eric Zhou of Harvard Medical School put it simply: “Even good sleepers vary from night to night.” A bad night after a perfect routine is not a failure. It is an ordinary night.

So the useful rule for any hack is the opposite of maxxing. Change one thing at a time. Judge it by how you feel in the day rather than by a score — “the best measure of sleep quality is how you feel upon waking,” as a sleep scientist told the Guardian. And drop anything that makes bedtime feel like a test. Why trying to sleep keeps you awake and orthosomnia go further.

When is a sleep problem not something to hack?

When it has lasted. If poor sleep happens most nights, has gone on for months and is affecting your days, take it to a doctor. The recommended first treatment for chronic insomnia is cognitive behavioural therapy for insomnia (CBT-I), in the guidelines of the American College of Physicians (Qaseem and colleagues, 2016) and the American Academy of Sleep Medicine (Edinger and colleagues, 2021).

And when the problem may be your breathing. Loud snoring, gasping or choking in your sleep, breathing that stops and starts, and feeling very tired every day are signs of sleep apnoea, which the NHS says can be serious if it isn’t diagnosed and treated — and exactly the situation in which taping your mouth is a bad idea. When snoring is a reason to see a doctor lists the signs.
