If you want to try something new to give your sleep a bit of a boost, why not try sleeping in the nude?
Over 2,500 volunteers were asked to wear different types of clothing or go to bed completely naked to work out who had the most rapid eye movement (REM) – the stage in which we dream, form memory and process emotions.
As well as sleep monitors, researchers got people to sleep in T-shirts and shorts, underwear, PJs with full sleeves, kimono robes, nightgowns, nightshirts, onesies, bathrobes and T-shirt or trouser PJs. And, of course, some wore their birthday suits.
Those who slept naked recorded an average of 26.5% REM sleep. The T-shirt and shorts group, and those wearing just underpants were not far behind.
At the other end, those in nightshirts, bathrobes and T-shirt/trouser combos recorded averages of less than 20% – the latter achieved just 17.5% REM sleep.
The study from TheDozyOwl also looked at whether socks were good for you.
They found people who slept with socks on had a little more REM sleep on average (27%) than those who slept with socks off (26%).
However, broken down into men vs women, the data shows that the average REM sleep had by male participants was higher without socks (26% with, 27% without), while women had more REM sleep on average with socks on (28% with, 25% without).
Why could naked sleeping improve the quality of your sleep?
Nudity can help lower your body temperature, which gives the signal to your body that it’s time to wind down for sleep. If you’ve got nice soft bedding, it means you’ll be able to enjoy it all over without PJs getting in the way.
On top of that, a study found that couples who slept naked were happier in their relationship than those who opted for PJs.
Stephanie Thiers-Ratcliffe of Cotton USA said at the time that this was largely thanks to the fact that skin-on-skin contact encouraged intimacy.
