A sleep expert has weighed in with a hack that could prove to be extremely useful if you're finding it difficult to get some shut-eye.
It's something that's pretty standard in European countries, but not many in the UK have adopted the habit.
And it could potentially save couples from a lot of arguments.

There are several things that could get in the way of a good night's sleep including being near your phone or sleeping with your partner in the same bed.
The latter has caused quite a stir, though something called the 'Scandinavian sleeping method' has come back into popularity as winter approaches.
Radiators are starting to be turned on, which is nice when you're awake, but the warmth can often be hard to fall asleep with as we often look for ways to stay cool at night, like poking your toes out of the covers.

But it looks like sleep experts are bringing back the well-known sleeping method from our friends over in Scandinavia, which went viral last year.
James Wilson, who is known as The Sleep Geek, explained to the Mirror that this method is a game-changer to get you a well-rested night.
Though it is fairly popular overseas, it seems like the UK are missing out, as he explains: "If you have a partner, sleep with two duvets instead of one.
"Usually in Northern European countries, like Denmark or Norway, couples have two duvets, so each person has their own when sleeping."

He went on to claim: "They think we in the UK are bonkers - why would you share a duvet? If you're a hot sleeper, laying next to someone, they're coming into your side of the bed, that makes you hot!
"Women in particular, because of the week before and during your period, your core temperature is a little bit too hot for sleep. So if you've got someone next to you, making you hotter, that's not good."
Wilson added that if you 'like a light duvet', while your partner likes a 'heavy duvet', someone always ends up losing, and it always ends in 'duvet wars'.

"That person says 'this is the duvet we're having' and you can end up with duvet wars where one person is saying, 'I've got the duvet, I'd like more of the duvet', or 'No, we’re having this [type of] duvet', you end up in this sort of battle," he explained.
But with your own duvets, he said that you get a better temperature for sleep, and there's no more fighting over the duvet. Nice.
But what about if you're single and are still finding trouble with regulating your body temperature at night?
Well, TikTok content creator Cecilia Blomdahl, who lives in Svalbard, Noway, near the North Pole, said she had an 'ultimate' hack for a sound sleep.

She advised: "Always air out your duvets as often as you can. If you can at least once a week and especially good if it's outside in the cold weather. It just makes them so fresh and airy and amazing."
