Exact temperature your body needs to be to fall asleep straight away, according to experts

If you've ever found yourself stuck in sleep purgatory, listen up.
There is nothing worse - an exaggeration but bear with me - than jumping into bed, getting ready for some sweet, sweet Zs and turning to look at the clock to find that four hours have passed any you're wide awake.
As the minutes tick by and the panic grows, you find your mind racing, going over every little past indiscretion or awkward encounter you've had.
Was I rude to the shop assistant eight years ago? Should I call my ex? Why do dogs sneeze?
It's a nightmare but without the benefit of actually being asleep.
Well, those days could be well behind you now that a sleep expert has given their top tip for a peaceful night's slumber.
Max Stevens, from The Sleep Checklist, recently looked through some of the most popular sleep hacks on TikTok to see what's what.
And one that stuck out to him as actually being pretty useful was making sure your room is a good temperature.
One TikToker claimed that it's important a room is between 18C and 20C in make sure you're in the best position to get some kip.
"This tip is great," said Max. "Your body needs a cool environment to fall asleep and keeping the temperature between 18 to 20 degrees is the perfect temperature for quality sleep too.
"Any cooler or hotter and it may affect your body's internal temperature. This is one of the main reasons why many of us find it hard to sleep in the warmer months."
And once you've got that sorted, you'll need to think about how you're going to sleep... especially when it's hot.
James Leinhardt is the founder of bed brand Levitex, and he recently explained what the best body position to ensure the best possible night's sleep.
So what does James suggest? Well, first things first: never sleep on your front.
James said: "The position we lie in is the big factor we can control when it comes to staying cool at night.
"The best position is one we call 'the dreamer', which means lying in the semi-foetal position."
That's basically on your side with your legs at a bit of an angle, there are other options though, if 'the dreamer' isn't your cup of tea.
James continued: "Optimising your sleep posture with a supportive mattress and pillow will help preserve the position you go to sleep in for longer, whether it's semi foetal side lying ‘dreamer’, or lying on your back ‘star gazer’ (but never your front unless for medical reasons)."
The 'star gazer' is just laying on your back, but the name is way nicer than telling someone to just sleep normally.
But why is this important? You may ask.
"Because if you toss and turn at night, your heart rate variability goes up," said James.
"This makes you warmer as more blood pumps around the body, so when temperatures are hotter, people generally get even warmer and more uncomfortable."
