The best way to improve your looks is to get some sound sleep, rather than spend a small fortune on lotions, potions or dresses.
Those who manage eight hours a night look far more attractive than those who are sleep deprived, say scientists from the Karolinska Institute in Stockholm, Sweden.
A group of healthy young adults were photographed after a good night’s sleep, and again after much less, reports the British Medical Journal.
Each picture was then rated on an attractiveness scale of one to 10 by members of the public. And the well-rested won hands down, according to the Daily Mail.
Young women who took part in the study were not allowed to use make up and had to wear their hair down for both photos, just in case a particular style was slightly more flattering.
On the first night they slept in their own homes and were told to go to bed at 11 p.m. and set their alarms for 7 a.m.
On the second night they were allowed to sleep no more than five hours and were monitored in the lab to ensure they did not get any more. The result? They looked much worse after less sleep.
“Sleep deprived people are perceived as less attractive and less healthy compared with when they are well rested,” said the study.
