How lack of sleep could be making you ugly

How lack of sleep could be making you ugly

And that's not all.

According to reports, researchers then took make-up free images of each of the participants after both the good and bad sleep sessions before asking more than 100 strangers - all from Stockholm - to rate the images on attractiveness, health, sleepiness and trustworthiness. Basically, if you look more exhausted, you also look more unhealthy, and this might trigger some diseases-avoiding reactions in others - which would explain why people would avoid socializing with sleep-deprived people.

"Telling someone they look exhausted says more about your perception of them than you might think", the study starts.

The good news is that these issues are fixable: just bloody well get some sleep, and, if you've had a rough night, expect that people may view you as slightly less approachable.

"Recent findings show that acute sleep deprivation and looking exhausted are related to decreased attractiveness and health, as perceived by others", they add.

Photographs of men and women aged between 18 and 47 after two nights of eight hours' sleep and two nights of four hours' sleep were compared by a group of 122 people.

Researchers found that lack of sleep can make you appear less attractive to others. They were also asked how likely they would be to socialize with the participants. After that, they were photographed by the researchers.

However, statistics show that around 1 in 3 adults in the United States fail to get the recommended minimum of 7 hours of sleep each night. In other words, people don't want to hang around with people who might be ill, whereas someone who looks energetic and fit will hold lots of appeal.

"This study is a good reminder of how important sleep is to us", Dr Gayle Brewer, a psychologist at the University of Liverpool told BBC News. And the fact that one might want to avoid contact with a "sleep-deprived, or sleepy-looking individuals" is a strategy that makes sense, evolutionary speaking, the researchers explain, since "an unhealthy-looking face, whether due to sleep deprivation or otherwise" signals a health risk. "Most people can cope just fine if they miss out on a bit of sleep now and again".

As a result, they were less attractive to potential partners and less likely to be chosen by friends and colleagues to socialise with.
