Lack of sleep has been blamed for everything from poor driving to memory problems. Now, researchers think they’ve started to pinpoint why: week-long sleep studies of people resting for 10 hours a night vs. six hours showed significant changes in gene activity.

“The surprise for us was that a relatively modest difference in sleep duration leads to these kinds of changes,” says study author Professor Derk-Jan Dijk, director of the Surrey Sleep Research Centre at Surrey University.
