  Sleeping helps you solve problems
Updated 22 January 2004, 13.27

Everyone knows getting a good night's sleep is important, but did you know it helps you think too?

German scientists think that your brain doesn't take a break while you're asleep, and instead keeps on thinking.

To prove it they got two groups of people and made them all take a test, with one group sleeping and one not.

They found the ones who slept worked out the answer more quickly, suggesting their brains had been trying to figure it out while the people were napping.

Before the groups split and one of them went to sleep, the scientists gave them a clue to solving the problem.

The scientists think that the sleeping group's brains were working hard at using the clues while those awake weren't.

If the groups weren't given a clue before putting their heads down there was no difference between their problem solving skills and the group who stayed up.
