A new study has revealed just how much lack of sleep can effect your looks (and that's putting it nicely).
According BBC News, researchers in Sweden say: "A couple of bad nights is enough to make a person look 'significantly' more ugly."
The scientists used photographs of healthy, predominantly young, students taken after either two nights of normal sleep (approximately eight hours a night) or two nights of disrupted sleep (approximately four hours a night). They then asked 122 people to rate how the strangers looked - how much they would like to socialise with the people in the photographs? How healthy, attractive, trustworthy and sleepy did they look? - and the results were telling.
The study found that on average, people were 2.1% less likely to want to socialise with people who'd had less sleep. It also found that people rated the strangers who'd had less sleep as less attractive and healthy.
Based on exactly when you need to wake up.
Bleugh. Not great news for a society that on average is underslept, is it?
