So here it is: beauty sleep is a real thing, and your exhaustion is wrecking your appearance. And that's not all. Participants were asked to get a good night's sleep for two consecutive nights and then a week later, they were required to only give themselves four hours sleep for two nights in a row. They also thought the exhausted subjects to be less attractive, less healthy and more sleepy compared to when they had enough sleep.
Furthermore, the study found that people's willingness to socialize with sleep-deprived people was only 2.1 percent less than their willingness to do so with fully rested people.
Unsurprisingly, insufficient sleep can take its toll on our appearance, with puffy eyes and a boring complexion being two of the tell-tale signs of a bad night's slumber - and, according to the new study, these effects do not go unnoticed by others.
Two consecutive nights of restricted sleep could be enough to make someone appear less attractive to others, as well as making people less interested in hanging out with them, according to a joint study from New York University and the Karolinska Institutet in Sweden.

They were also asked if they would like to socialise with the person in the photo, the "Los Angeles Times" reported. After that, they were photographed by the researchers. These people were asked to rate the subjects on attractiveness, health, sleepiness and trustworthiness. As it turns out, not getting enough sleep made participants score worse on all counts. However, plenty of people fall short of getting as much sleep as they need - Gallup reports that 42 percent of adults in the US don't get enough shut-eye. However, Dr Sundelin also pointed out, "I don't want to worry people or make them lose sleep over these findings though". So for now, try your best to avoid those lost hours of mind-numbing Instagram scrolling before bed-and get some damn beauty sleep.
'An unhealthy-looking face, whether due to sleep deprivation or otherwise, might activate disease-avoiding mechanisms in others, ' say the researchers. These are small tweaks, but they can help you nab more sleep and change how the world perceives you.
As a result, they were less attractive to potential partners and less likely to be chosen by friends and colleagues to socialise with.
