The Effects of Sleep on Perception of Beauty Apparently, beauty sleep i a real thing. A ccording to recent research by The Karolinska Institute and published in the Royal Society Open Science journal, a couple of sleepless nights is enough to make a person significantly less attractive. The researchers asked 25 university students, some male and some female, to be the guinea pigs in a sleep experiment. The volunteers were given a kit that would measure their nighttime movements. They were asked to get a good night’s sleep for two consecutive nights. A week later, they were asked to restrict themselves to only four hours of sleep per night for two nights in a row. The researchers took makeup free photos of the volun- teers after both the good and the bad sleep sessions. Next, they asked 122 strangers—women and men living in Stockholm—to have a look at the photos and rate them on attractiveness, health, sleepiness and trustworthiness, as well as asking them: “How much would you like to socialize with this person in the picture?” The strangers could affectively tell if the person in the photo was tired, and, if they were sleepy, their attractiveness score suffered. The strangers also said they would be less willing to socialize with the tired students, who they also perceived to be less healthy. The Karolinska Institute researchers says this makes sense in evolutionary terms. “An unhealthy-looking face, whether due to sleep deprivation or otherwise, might activate disease-avoiding mechanisms in others,” says Dr. Tina Sundelin, lead researcher in the study. “I don’t want to worry people or make them lose sleep over these findings though. Most people can cope just fine if they miss out on a bit of sleep now and again.” As spa professionals, be sure to discuss sleep as an important piece of the client’s beauty and wellness regimen. Creating spa treatments that specifically address sleep issues can help those who struggle with getting a good night’s sleep address their beauty concerns. n November 2017 ■ PULSE 17
