Lack Of Sleep Really Does Make You Less Attractive, Study Suggests

Woman asleep

The study found that after only two nights of shorter-than-normal sleep, people are not only viewed by others as being less attractive and less healthy than after they are fully rested, they are also seen as less appealing to socialize with.

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

25 Swedish students were studied upon which included 14 women, 11 men- aged 18 to 47 years old, who had their pictures clicked after two consecutive nights of poor quality sleep, just 4.25 hours and also after when they had a proper sleep of about 7.5 hours. They were also asked to rate participants' attractiveness, health, sleepiness, and trustworthiness. The strangers also said they would be less willing to socialise with the exhausted students, who they also perceived to be less healthy, Royal Society Open Science journal reports. "An unhealthy-looking face, whether due to sleep deprivation or otherwise, might activate disease-avoiding mechanisms in others". However, researchers tell people they shouldn't worry too much about this.

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

'Star Wars' influences top baby names; Caitlyn plunges in popularity
In 1966, about 80,000 babies were named Michael, the top name for baby boys that year. The drop comes a year after Caitlyn Jenner announced her new name and gender.

Dr Sundelin said: "These are notable differences and, as such, fair arguments for prioritising a good night's sleep and using other methods to reduce a sleepy appearance before interacting with people". "A couple of participants were even rated as more attractive after sleep restriction". Or, she adds, it could also be that we tend to assume that people who look exhausted aren't going to be in the mood for socializing. "Most people can cope just fine if they miss out on a bit of sleep now and again". Researchers also asked, "How much would you like to socialize with this person in the picture?"

Why would we - apparently, unconsciously - want to avoid people who get too little sleep?

You know that it's important to get a good night's sleep, and odds are you probably try to do the best that you can.

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