They were four to five percent more likely to die than those sleeping six hours. Even those sleeping five hours had lower death rates than individuals who slept eight hours.

And those who sleep for nine or ten hours a day have a mortality equivalent to people who are moderately obese, somewhat more than all the other sleeping groups, the research concluded.

"We don't know what the causal factors are," Kripke said in an interview. "But it's possible that sleeping too much, like eating too much, is bad for your health. And it might be true that a little bit of sleep or sleep restriction, like reducing your diet, could be good for your health."
