Skipping your beauty sleep may make people avoid you

Skipping your beauty sleep may make people avoid you

Beauty sleep is officially a real thing, according to researchers who suggest that people who don't get a decent night's kip appear less attractive to others.

According to researchers from Karolinska Institutet in Sweden and New York University in the USA said,"People seem to be able to tell when someone needs more sleep, and are more inclined to leave them alone in that case".

In the new study, 14 women and eleven men were photographed after having either eight or four hours sleep for two nights running.

Here's what they discovered: People were less inclined to want to socialize with those who hadn't gotten enough sleep.

"An unhealthy-looking face, whether due to sleep deprivation or otherwise, might activate disease-avoiding mechanisms in others", researchers from Sweden's Karolinska Institute said.

"A healthy, attractive face is characterized by a certain degree of redness, which in turn is indicative of increased vasodilation and vascularization", they write.

The study published in the Royal Society journal Open Science is the third to connect poor sleep to a less attractive and less healthy appearance.

The team, lead by Dr Tina Sundelin, found that strangers were good at assessing how exhausted a person was, and that they rated the sleepy set of photographs as less attractive than the photos of the same people when they were well-rested.

That's potentially a problem for a lot of people: According to the National Sleep Foundation, adults over the age of 18 need a minimum of seven hours of sleep a night - and many don't get that. Strangers were also less likely to want to socialise with that person.

You know the drill: You haven't had a good night's sleep for a few days and now you don't like what you see in the mirror - puffy eyelids, dark circles, sallow skin. "Most people can cope just fine if they miss out on a bit of sleep now and again".

The study authors found that overall, raters were less willing to socialize with tired-looking subjects compared with those who were well rested.

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

Still, the findings are interesting - if only as a reminder of the many ways that not getting enough sleep can negatively affect your wellbeing, including, apparently, your social wellbeing.
