AVERAGING less than seven hours sleep a night more than doubles the risk of having a stroke – even if you top up your rest with an hour or more nap, researchers from Ningxia Medical University in China say.

Fragments can then break off and travel to the brain, cutting off its blood supply and so causing stroke.
