Sleep- Deprived People 'Look Sad, Unhealthy And Unattractive'

People who are sleep-deprived look sad and less attractive, new research suggests. Swedish researchers found that people also think that sleep deprived individuals look unhealthy. The researchers believe that these perceptions could influence the way in which people treat those who are sleep deprived. Researchers at the University of Stockholm photographed people on two occasions – once after a good night’s sleep, and once after they had been awake for 31 hours, The Atlantic reports. The team then asked 40 people to rate the pictures on how tired, sad and attractive the subjects looked. They discovered that people’s eyes take the heaviest toll from sleep deprivation and that they become redder and more swollen. They also develop dark circles and the eyelids start to ‘hang’. The researchers also discovered that sleep deprived people tend to be perceived as having paler skin, more wrinkles and droopy corners of the mouth. Tina Sundelin, lead researcher, told The Atlantic: ‘Since faces contain a lot of information on which humans base their interactions with each other, how fatigued a person appears may affect how others behave toward them.’
