Sleep really does make you beautiful.

It is a well known myth that getting in a full eight hours of sleep each night improves our appearance. However, most of didn’t believe it to be true. But now new research from the Karolinska Institute in Stockholm has proved that it very well could be. The researchers took 23 young men and women and took photographs of them after an eight hours rest, and then again after they volunteers had remained awake for 31 hours. Untrained observers were then asked to rate the faces, and who would have guessed it, the results showed that after a normal nights kip the volunteers looked more attractive and healthier.

The authors wrote in their paper published in the British Medical Journal: "Sleep deprived people are perceived as less attractive, less healthy and more tired compared with when they are well rested."

So what more of an excuse do you need to jump into bed early?
