Ever roll out of bed and look in the mirror after a few late nights in a row and just think “Gross?” Unfortunately, you’re right. Everybody thinks you’re gross. According to a study by The Royal Society, acute sleep deprivation and looking tired are related to decreased attractiveness and health, as perceived by others. Researchers took photos of participants after both good and bad nights of sleep, then had those photos rated by strangers, judging the subject’s attractiveness, health, and trustworthiness. The images after bad nights of sleep scored lower on attractiveness and health, as well as the strangers noting they would be less likely to socialize with tired looking individuals. So go take a nap. InsightCity said it’s ok. How much do you sleep?
