Is Beauty Sleep Actually A Real Thing?

(Telegraph) Beauty sleep is real – too little sleep leaves you less attractive, study finds 

There really is such a thing as beauty sleep – and people who don’t get enough of it do appear less attractive to others.

That’s the verdict of a new study by researchers at Stockholm University, published in the Royal Society Open Science journal.

The research involved 25 volunteers who agreed to be photographed after having had two consecutive nights of good sleep, and then again after having had only four hours sleep for two nights in a row.

122 members of the public were then asked to look at the photos, giving each person pictured a rating for attractiveness, health, sleepiness and trustworthiness – and a response to the question: “How much would you like to socialise with this person in the picture?”

When sleep-restricted, the volunteers were perceived to be less attractive, less healthy and more sleepy – and the raters were less inclined to socialise with people who hadn’t had enough sleep. There was no difference in perceived trustworthiness.

“These findings suggest that naturalistic sleep loss can be detected in a face and that people are less inclined to interact with a sleep-deprived individual,” researchers said.

Dr Gayle Brewer, a psychology expert at the University of Liverpool, told the BBC: “Judgement of attractiveness is often unconscious, but we all do it, and we are able to pick up on even small cues like whether someone looks tired or unhealthy.

“We want our partners to be attractive and energetic. This study is a good reminder of how important sleep is to us.”
