Sleep on it

A good night's sleep can help you think better and solve problems more effectively.

German scientists say they have demonstrated for the first time that our sleeping brains continue working on problems that baffle us during the day, and the right answer may come more easily after eight hours of rest.

The German study is considered to be the first hard evidence supporting the common sense notion that creativity and problem solving appear to be directly linked to adequate sleep, scientists say. Other researchers who did not contribute to the experiment say it provides a valuable reminder for overtired workers and students that sleep is often the best medicine...

Scientists at the University of Luebeck in Germany found that volunteers taking a simple math test were three times more likely than sleep-deprived participants to figure out a hidden rule for converting the numbers into the right answer if they had eight hours of sleep. The results appear in Thursday's issue of the journal Nature.

Here is the full story. Here is another account, with a link to the original research. I will note that I typically review previously written MR postings after a night of good sleep.
