Should You Sleep Naked?

Last year, Forbes published an op-ed by Travis Bradberry championing an unusual argument: All people have to do to be healthier, wealthier, better rested, and slimmer is to sleep naked. Only eight percent of sleepers report going to bed in the nude every night, he says— everyone else is missing out.

Bradberry’s argument is that sleeping naked is one of the easiest ways to keep the core body temperature low, which is important to sound sleep. The good night’s sleep is what produces all the other effects: better brain function, lower cortisol levels, and even a slimmer waistline.

For that last claim, he cites a National Institute of Health study indicating that keeping the core body temperature low overnight leads the body to burn more fat to stay warm as people sleep.

It’s a common enough argument. Men’s Health Magazine, Cosmopolitan, Elite Daily, The Huffington Post, and a slew of other publications have published articles promising that sleeping in the buff will do everything from making one’s hair shinier to improve their sex life, all because it creates a better night’s sleep. But does sleeping naked actually produce a better night’s sleep?

The research indicates that it can, but it’s certainly not necessary. “…Wearing heavy blankets or clothing to bed will impede the release of growth hormone, which means people won’t burn fat while they sleep or benefit from night-time repair of their bones, skin, and muscles, said Natasha Turner, a naturopathic doctor, in an article for the Canadian edition of The Huffington Post.

But there are lots of ways to avoid these problems without throwing away one’s pajamas, and in fact, there are no studies that show that sleeping in pajamas is bad for someone. Neither are there any studies to show that sleeping naked is bad for them.

Rather, it’s a question of preference. If the sleep shirt someone has for years is what produces their best night’s sleep, then that’s the best option. The important thing to consider is how their pajamas affect their overnight temperature.


If your sleepwear is making you hot, try switching to a lighter fabric or shorter sleeves, or adjusting the temperature in your room. Then again, if you’re feeling adventurous, it may be worth experimenting with sleeping nude to see if it makes for sounder sleep. Bradberry swears it will make you more confident, though there’s no hard data to back that up.

Sleeping naked does have one proven advantage for couples: increased skin to skin contact promotes the production of oxytocin, says Turner, which lowers cortisol and blood pressure, and promotes intimacy. Whether that creates a better night’s sleep is up to the couple to decide.
