TikTok trend claims pineapple helps you sleep – is it true?

If you find yourself tossing and turning in bed, unable to fall asleep no matter how tired you are, maybe you should try eating some pineapple.

Or at least, that's what the latest TikTok trend claims.

Racking up millions of views, videos featuring the hashtag #PineappleHacks have some people claiming that the fruit has helped them get "the best sleep ever".

But is there any science behind it?

It's been found that pineapple can increase melatonin in the body – a hormone that helps to reset your circadian rhythm. Melatonin doesn't magically make you sleepy, but a higher level of melatonin in the body signals to your brain that it's time to fall asleep for the night.

So if you have lower-than-normal melatonin levels that are preventing you from falling asleep, eating pineapple could potentially help.

If you don't believe the science, there are plenty of users on TikTok touting the benefits of pineapple in getting a good sleep.

"Eat pineapple before bed if you struggle with sleep," certified nutritionist Emma Leigh wrote in her caption.

"Pineapple has been shown to increase melatonin in the body by 240 per cent," she said. "Eating pineapple before bed helps me fall asleep faster and sleep so much deeper."

Another user, a health coach, says that she snacks on frozen pineapple before bed or blends it into a tea to help her sleep.

"It's also great for waking up not puffy!!," she wrote in the video's caption.

Pineapple isn't the only food that will help your body produce melatonin.

Tart cherry juice is another miracle food that some people swear by to help them sleep. Recent research from Louisiana State University found that drinking the stuff twice a day helps insomnia sufferers sleep for 90 minutes more on average.

Honey also has the same effect, by spiking your insulin levels, releasing tryptophan, which becomes serotonin and then melatonin.

Another sweet treat that can help you sleep is kiwi fruit, which is rich in potassium, calcium, phosphorus, folate, magnesium and more. A study from Taiwan found eating two kiwis an hour before bed significantly improved sleep.

Of course, one of the biggest factors affecting your body's melatonin levels is screen time before bed.

Tim Stephenson, a sleep physiologist with sleep health company ResMed says "we need to limit that especially just before bedtime."

"Light impacts production of melatonin, so when we are on our screens at night it is delaying the production of melatonin which is important in the overall sleep process."
