Narrator: This is Science Today. We've probably all experienced sleep deprivation at one time or another that affected our efficiency at work or school the next day. Matthew Walker, director of the University of California, Berkeley's Sleep and Neuroimaging Laboratory says one of the main reasons people say they don't get enough sleep at night is because they have too much to do during the day.
Walker: If you tell me that you need to do more during the day in the hours that you have, I'm going to tell you to achieve that, you don't need to spend more hours doing it, you need to get more sleep.
Narrator: Walker, who plans to design a study about this issue, says getting enough sleep increases efficiency during the day and the more you shortchange your sleep, the more inefficient you will become.
Walker: So you're seemingly needing more and more hours in the day to get done what you need to get done. The prescription, I believe, is a solid night of sleep and therefore, what may have taken you ten hours in the day to complete at work could take you eight hours in the day to complete.
