Michael Perlis, who heads research on insomnia at Penn, says the worst thing one can do is try to regain control by attempting to compensate for sleep loss, reports NewsWorks.

“The very best thing that you can do is absolutely nothing — you don’t sleep in the following morning no matter how tired you are, you don’t nap, and you don’t go to bed early,” he said.

Perlis’ research team has provided the early data that could ultimately confirm that theory, based on findings from sleep diaries kept by 1,000 people.
