Some on social media claim that mouth taping, which involves sealing your lips shut with a piece of skin-friendly adhesive, can prevent snoring and improve sleep by forcing you to breathe through your nose.
While it’s true that breathing through your nose can help reduce snoring, there’s no strong evidence that mouth taping improves sleep quality, said Dr Akinbolaji Akingbola, a sleep medicine physician at the University of Minnesota.
Regular snoring can be a symptom of obstructive sleep apnea, a condition marked by potentially dangerous pauses in breathing during sleep. If you use mouth tape to stymie snores instead of seeing a doctor, you might miss the chance of diagnosing a real medical condition and receiving proper treatment, Kansagra said.
2. Limit blue-light exposure.
Blue light, a type of light emitted by electronics like televisions, smartphones, laptops and many bright light bulbs, can trick your brain into thinking it’s daytime, keeping you alert, said Andrew W. McHill, a sleep and circadian rhythm scientist at Oregon Health & Science University.
Any trend that encourages avoiding blue light before bedtime (or replacing blue-light emitting light bulbs in your home with ones that emit amber or red light, as some on social media recommend) will probably help you sleep, the experts said.
Beginning one to three hours before you go to bed, Akingbola recommended dimming bright lights and using fewer electronics. Even limiting your exposure for just 30 minutes before your bedtime can help, Kansagra said.
But don’t assume that certain products or product features, such as blue-light-blocking glasses or blue-light filter modes on electronics (like the “Night Shift” feature on Apple products), will actually reduce your exposure enough to improve your sleep. There isn’t strong evidence that they block enough blue light for this effect, said Dr Angela Holliday-Bell, a sleep physician in Chicago.
3. Don’t use supplements as sleeping pills.
Bryan Johnson, a tech entrepreneur and longevity influencer, says he takes a low dose of melatonin every night – as part of his elaborate daily supplement regimen – to help him get a perfect night’s sleep. Andrew Huberman, a neuroscientist and popular podcast host, claims that certain types of magnesium supplements can shorten the “transition time into sleep” and promote deeper sleep.
While these supplements can be useful for certain situations – melatonin, for instance, can help you adjust to a new time zone, and there is some (albeit very limited) evidence that magnesium supplements might help certain people fall asleep faster – the experts we spoke with didn’t endorse using these supplements as regular sleep aids or as treatments for chronic insomnia.
They aren’t likely to be toxic when taken as recommended, Kansagra said. But using them every night could be harmful in other ways. They can be expensive and aren’t well-studied, so you might be spending a lot of money on something that isn’t proven to help. And they may become a crutch for a potentially more serious sleep issue that could require a proper diagnosis and treatment plan.
4. Try certain mental exercises
Social media is teeming with mental sleep hacks – like the classic “counting sheep” approach – that only require your imagination.
One exercise, called cognitive shuffling, involves thinking of a word (“whale,” for example) and then coming up with as many other words that begin with the same first letter (“w”) as you can. Then, you move on to words that begin with the second letter (“h”), then the third, and so on until you fall asleep.
Another mental exercise involves imagining a familiar house (not your own) and mentally walking through every room. Picture the house in as much detail as possible, focusing on its doorways, furniture and artwork. Some people on TikTok say it works so well that they never make it upstairs before falling asleep.
These methods haven’t been rigorously studied, but it makes sense – at least in theory – that they may help some people fall asleep, said Allison Harvey, a professor and clinical psychologist at the University of California, Berkeley. Such mental exercises can distract you from any worries or stress-inducing thoughts that may be keeping you up, she said.
However, they won’t work for everyone, she added – they should be just one of many sleep-inducing strategies you use.
5. Keep a worry journal.
Whether you use a dedicated journal or a blank piece of paper, writing down any anxiety-provoking thoughts before bed – as some tout on social media – can help you fall asleep, Harvey said.
When you carve out dedicated “worry time,” as she calls it, to jot down any fears, cumbersome tasks or problems you’ve been trying to solve, your brain has a chance to process them before you try to nod off.
If you don’t give yourself this space, which is ideally two hours between doing the exercise and falling asleep, Harvey added, you risk lying in bed with your mind racing.
Akingbola agreed that writing about your worries in a journal can help you fall asleep. But try to avoid doing it in your bed, he said, so that you don’t create a negative association between it and stressful thoughts.
