If you're not getting enough sleep during the work week, researchers say you can't make it up on the weekends.

They say people who are sleep-deprived during the week need more than just a couple nights' rest to recover.

Scientists at Pennsylvania State University studied healthy people in their 20s in a sleep lab. After a few nights of getting six hours of sleep, followed by a couple of 10-hour nights, the participants still scored low on psycho-motor tests.

However, women appeared to recover better than men.
