Before you order a new pair of flannel PJs for the cool weather, you might want to hear this. According to a study from the UK, sleeping naked is good for your health. And it turns out, it helps with everything from skin to fertility, so you may want to give it a try.
With 40% of Brits reporting they typically don’t get a good night’s sleep, Dr. Sarah Brewer points out that this could be because of their sleepwear. She explains that sleeping naked allows your body to remain cooler during the night, so you may sleep better by not being overheated. Being just three to four degrees warmer can increase the chances of waking up and reduce deep sleep, which we feel the next morning.
Brewer says another problem with being too warm when we’re sleeping is that it makes the body produce more cortisol (the stress hormone) than usual, which leads to an increased appetite. And if you’re too hot while you sleep, your body won’t release as much human growth hormone, which helps repair cells. So basically, your cortisol level stays high, leaving the body in “panic mode” instead of “healing mode” and it stores fat instead of burning it.
And we can’t talk about the benefits of sleeping naked without mentioning the appeal of it when you share a bed with your S.O. Brewer says, “Humans are highly-tuned to the sight of bare skin, which acts as a signal for sexual arousal.” So that’s one more reason to ditch the jammies tonight.
