Beauty Sleep -- Truth or Fantasy?

Many people assume that “beauty sleep” is a myth used to convince children to go to sleep. But a new study suggests there may be something to it.

The study looked at the effect that how much you sleep has on the way other people perceive your attractiveness. Study participants were asked to sit for photographs. The photos were identical, except for one thing -- some of the participants had had a full night's sleep the night before, while others had been awake for 31 hours straight.

According to Time Magazine:

“The photos were then shown to a group of 65 different people, who, knowing nothing about how tired the people in the photos were, rated their attractiveness. The observers rated the sleep-deprived as less healthy looking, less fetching and, obviously, more tired-looking.”
