In this heatwave it can be tempting to strip off before slipping into bed and sleep in the nude.
But, experts are warning that snoozing in the buff will give you a worse night’s sleep than putting some PJs on.
Dr Guy Leschziner, consultant neurologist and sleep physician at Guy’s and St Thomas’ Hospitals, told BBC Radio 4’s today show: “People may be better off sleeping in clothing rather than sleeping naked.
“If you’re wearing a natural fabric like cotton it acts as a wick for your sweat and it can increase the surface area for the sweat to evaporate, thus may make you feel much cooler.”
He’s not the only expert who advises against sleeping naked, sleep evangelist Dr Sophie Rostock also told Women’s Health: “I've seen a lot of advice about sleeping naked.
“But this isn't super helpful as what you can actually find is if sweat collects on the body, and isn't whipped away by a moisture-wicking surface – like you get from clothing – then it doesn't help you cool.”
And, that’s not the only sleeping hack you should steer clear from, as putting your sheets or pyjamas in the fridge or freezer won’t help either.
Sleep environment expert James Wilson, also known as the Sleep Geek, told Mirror Online: “When hot weather comes around there are some tips given out that may sound like they would work when actually they really really don’t.
“An example of this may be put your bedding/pyjamas in the fridge or freezer or to wear wet socks to bed, but they both have the same problem.
“These approaches will add more moisture to your sleep environment and that moisture will heat up during the night.
“This means that although it may cool you down as you go to bed during the night this moisture will heat up and is likely to wake you as you come out of your sleep cycle.”
Having our undies next to our cheese is far from appealing anyway. So what can you do to keep cool during the night?
The National Sleep Foundation advises to keep your windows, blinds or curtains closed during the day to keep the sunlight out and the hot outside temperature out.
They also recommend taking a lukewarm shower before bed, although you shouldn’t have it too hot because that will increase humidity in your home.
Having thin cotton sheets on your bed also helps to keep your bed slightly cooler.
Sleeping naked isn’t the only thing you should avoid in the hotter weather, as driving in flip flops could cost you a whopping £5K .
