Does Sleepmaxxing Actually Work?

Sleepmaxxing is all over TikTok. Magnesium mocktails, mouth tape, chin straps, a ring that scores your night out of 100. The name comes from "looksmaxxing", the trend for improving how you look, pointed at sleep instead. Do enough of it and you'll supposedly sleep better than you ever have.

Does it work? Some of it. The parts with real proof behind them are free. Most of the things you'd have to buy don't have much behind them at all, and one or two can make your sleep worse.

The short answer

Strip away the name and most of sleepmaxxing is ordinary sleep advice. Same bedtime, same wake-up time, a dark room, a cool room, daylight in the morning, and going easy on caffeine and drink. Doctors have said all of this for years, and it works.

The new bits are where it falls apart. Supplements, trackers, tape. Some do nothing much. A couple are worth steering clear of.

It depends on how you sleep at the moment

Most adults need seven to nine hours. If you're getting nowhere near that, and your room is warm or bright, or you're in bed at midnight one night and 2am the next, then sorting those things out will help a lot. That's where nearly all the benefit is, and none of it costs anything.

If you already sleep well, there's not much left to fix. Every extra thing you add does less than the last one did. At some point you stop improving your sleep and start giving yourself a score to worry about at 3am.

So work out which of those two you are before you spend anything.

What actually works

None of this is exciting. All of it is free.

Get up at the same time every day

If you only change one thing, change this. Waking at the same time keeps your body clock steady, and a steady body clock is what makes you tired at a sensible hour.

That includes weekends, which is the part people hate. A long lie-in on Saturday throws the whole thing off, and you end up wide awake on Sunday night wondering why. Sort your mornings and your evenings tend to sort themselves.

Get daylight in the first hour

Daylight in the morning tells your brain the day has started, which sets the clock for when you'll feel sleepy later. It's free and it takes ten minutes.

Winter here makes it harder. Between October and March there isn't much light about, and what there is arrives after a lot of people have started work. A walk at lunchtime still counts. Even a grey day outside gives you far more light than sitting under a bulb indoors.

Make the room properly dark

Darker than you'd think. A bit of streetlight through thin curtains, a standby light on the telly, a phone charging next to you. It all adds up while you're asleep. Blackout curtains sort most of it, or an eye mask for a few quid if you're renting.

Screens are the other half of it. The light from a phone holds off the melatonin your body uses to wind down, so putting it away an hour before bed is one of the more reliable things on this list. It's the scrolling as much as the light, mind.

Keep the room cool, 16 to 18°C

Your body has to cool down a little to fall asleep and stay in deep sleep. Most sleepmaxxing videos say 60 to 67°F because they're made for Americans. In our money that's 16 to 18°C, which is cooler than a lot of UK bedrooms with the heating running into the evening.

Turn the bedroom radiator down before you go up, and open a window if you can. A warm bath an hour or two before bed does the same job the other way round, because it's the cooling down afterwards that helps you drop off.

Move about during the day

Exercise is one of the best-proven ways to sleep better, and it hardly gets a mention online because there's nothing to sell with it. It doesn't have to be the gym. Just moving regularly through the week helps you fall asleep faster and wake up less.

Training hard late at night leaves some people wired, so try it earlier before you give up on it.

Watch the caffeine and the drink

Caffeine sticks around far longer than most people realise. That afternoon coffee can still be working at bedtime, so try moving your last one to early afternoon and see what happens.

Alcohol is the sneaky one. It knocks you out quickly, then breaks up the second half of the night and eats into the deep sleep that does you good. That's why you can get eight hours after a few drinks and still feel rough. There's more on this in our guide to what happens to your body when you sleep.

What probably won't do much

None of this is risky. It's just oversold, and a lot of what people notice is simply believing it'll work.

Magnesium and the "sleepy girl mocktail"

The proof that magnesium helps you sleep is weak, and most of it involves people who were short of it to begin with. If you want to try it, glycinate is the type usually suggested because your body takes it in better. Too much upsets your stomach, and it isn't suitable if you have kidney trouble.

Kiwis and cherry juice before bed

Eating more fruit won't do you any harm. There just isn't enough proof it does anything for your sleep in particular.

White, pink and brown noise

Handy for covering up a noisy road or a snoring partner. Not much sign it improves your sleep on its own.

Weighted blankets, red light, nasal strips and breathing exercises

Small studies, people saying they feel better, nothing solid underneath. Breathing exercises are the best of the bunch, mostly because winding down before bed helps either way. Same goes for meditating before sleep.

What can make things worse

Mouth taping

The idea is that taping your lips shut makes you breathe through your nose. The research is thin, and what there is isn't very good.

The real problem is safety. If your nose is blocked, or you've got a bent septum, or you might have sleep apnoea, taping your mouth shut cuts off air at the worst possible moment. That's a genuine risk, not a theoretical one. Loud snoring, gasping or choking in the night means a trip to the doctor, not a trip to buy tape. The NHS explains the signs of sleep apnoea and what to do.

Sleep trackers

There's even a name for getting anxious about your sleep data. Orthosomnia. You see a low score, worry about it, then sleep worse the next night because you're worrying.

Trackers are fine for spotting patterns over a few weeks. They can't diagnose anything, their guess at your sleep stages really is a guess, and how you feel in the morning tells you more than the number does.

Skipping the alarm and cutting out drinks

Waking up naturally sounds lovely, but it works against the regular wake time that actually helps. And don't go to bed thirsty to save yourself a trip to the loo. If you're up that often, mention it to your doctor rather than going without water.

What UK readers should know

You can't buy melatonin here

Not over the counter, anyway. It's been a prescription-only medicine in the UK since 1995, so a good chunk of the sleep advice online is telling you to take something you can't legally buy in a shop.

Your body puts out a tiny amount of melatonin as it gets dark. It's a signal, not a sleeping pill. The versions sold abroad are many times stronger, which is part of why they're controlled here. Anything sold online without a prescription isn't checked, and testing keeps finding the real dose is nothing like what the label says.

It can also hide a bigger problem. Melatonin shifts your body clock, so it suits things like jet lag. If stress or pain or a breathing problem is keeping you up, it covers the symptom while the cause carries on.

The advice is written for American houses

Fahrenheit, air conditioning, bright mornings. Our houses are draughty in winter, stuffy in summer, often single glazed, and almost never cooled. Take the idea, ignore the detail.

The one thing no gadget can fix

If you're waking up aching, too hot, or every time your partner rolls over, no amount of tape or tracking will help. That's the bed. Being disturbed by a partner is often just a bed that's too small for two adults, and our bed and mattress sizes guide is the quickest way to check.

We'll be straight with you. Most people don't need to buy anything to sleep better. Sort your wake time and your room out first. If it's a noise waking you rather than discomfort, that's usually a loose bolt or a slat rubbing, and our guide to stopping a bed creaking will get you further than a new mattress.

That said, a mattress that's sagging or well past its best will keep waking you up no matter how good your habits are. Our guide on how to choose the right mattress covers when it's genuinely time to replace one. If it's a restless partner, zip and link beds are two singles joined together, so their side moving doesn't come across to yours.

When you need treatment, not tips

If you've been sleeping badly for over a month, that's insomnia, and there's a proper treatment for it. CBT-I is a version of talking therapy built around sleep, and it's what NICE recommends before sleeping tablets. In a lot of areas you can get it free on the NHS as an online course. The NHS page on insomnia explains when to see a GP.

Sleeping tablets are a short-term fix at best. They don't touch the cause, which is why GPs rarely hand them out now.

Breathing trouble is a different matter. Snoring with gasping or pauses needs looking at properly, because sleep apnoea won't respond to anything on this page.

Does any of this work if you work shifts?

Some of it. A set wake time isn't realistic when your shifts move around, so darkness and temperature have to do more of the work. Blackout blinds are close to essential if you're sleeping in the daytime.

Get outside when your shifts allow rather than at a fixed time, and judge your caffeine by when you're going to bed instead of by the clock.

Shift work is harder on sleep than anything sleepmaxxing was built for. If it's really getting to you, that's worth raising with a doctor too.
