During this hot, sticky heatwave many of us shed our usual pyjamas and night clothes and sleep in the nude. After all, it’s just too warm to sleep in extra layers.

But according to bedding website Sleepypeople.com, there are a number of health benefits of sleeping naked. From helping your skin to boosting your metabolism, there might even be enough reasons to retire your pjs once and for all.

It can help your skin

There are certain parts of us that never get to enjoy the benefits of fresh air. And one such reason that baring all might be good for your skin to feel the fresh air is that it helps to lower the risk of some skin diseases, in particular, athlete’s foot.

It can help keep cortisol in check

Cortisol is a biochemical in our body which must be looked after as best you can.

When you’re overheated in bed, cortisol levels tend to rise. This can lead to increased anxiety and stress, cravings for bad food and ultimately weight gain.

Sleeping naked gives your body the best chance of regulating it’s own temperature and keeping that cortisol down.

It can help you sleep through the night

How many times have you found yourself waking up in the middle of the night because of an uncomfortable piece of sleepwear, a twisted T-shirt or a badly placed drawstring?

If that sounds like you, why not take away the annoying clothing and get a good night’s sleep as a result.

It can help with men’s fertility

A study from the National Institute of Child Health and Development at Stanford University found that men who slept in the nude had a 25% lower rate of damaged DNA in their sperm than men who wore boxer shorts or briefs.

Following the study, Allan Pacey, a leading fertility expert at the University of Sheffield told the New York Times: “We have known for some time that men who increase the temperature of their testicles, either through the heat exposure at work or by wearing tight underwear, have poorer semen quality compared to men whose testicles are cooler.”

It can boost your metabolism

A number of different studies have shown that sleeping in a cooler environment allows the body to produce healthy fats which burn calories to help generate body heat.

Sleeping in a warmer environment doesn’t have this effect, therefore metabolism is less effective. No clothing equals a cooler body temperature.
