HAVING a lie-in at weekends reverses the harm done by not sleeping enough during the week, a study suggests.
Adults who kip for just five hours a night are 65 per cent more likely to die prematurely than those who doze for seven.
But the greater risk can be eliminated entirely by getting eight hours of shut-eye on a Saturday and Sunday. Researchers found “catch-up” sleep is beneficial after analysing data on 43,880 people.
Those who slept for seven hours a night had the lowest risk of dying young from any cause.
Prof Torbjorn Akerstedt, of the Karolinska Institute in Sweden, said: “The results imply that short weekday sleep is not a risk for mortality if it is combined with a medium or long weekend sleep.”
Younger adults averaged less than seven hours on weekdays and eight at weekends. The elderly always had about seven.
Research has shown sleep loss cut sex drive and raised the risk of obesity, heart disease and diabetes.
