People who sleep less hours are considered less attractive
Many kinds of research have found a number of reasons for avoiding sleep deprivation: it makes us pessimistic and less sociable, it makes a dent in our empathy for others, makes us less understanding, and increases the likelihood of accidents. It is also proven that lack of rest makes people more irritable.
To reach these conclusions, Sundelin and his colleagues photographed 25 people after two nights of normal sleep and, again, after two who had slept only four hours. When they had the images, they asked 122 people to evaluate the photos taking into account their attractiveness, health, drowsiness, and honesty. The volunteers who looked at the photos acknowledged that they were not in the business of relating to those who had not rested properly, considering them less attractive, healthier and, of course, too sleepy.
