Barely three hours of sleep

Now researchers believe there could be biological reasons why those aged 10 to 20 need to sleep later and longer than the rest of us. About nine hours, to be exact.


Tests by Professor Russell Foster, chairman of circadian neuroscience at Brasenose College, Oxford, suggest that students perform better in the afternoon, because their body clock is programmed about two hours later, possibly for hormonal reasons.
"There's a biological predisposition for going to bed late and getting up late. Clearly you can impose upon that even worse habits, but they are not lazy."
