University of California, San Diego School of Medicine scientists say sleeping may help you make better decisions.
They believe rapid eye movement or 'REM' sleep may help fuel creative problem-solving by encouraging the formation of associative networks in the brain.
The findings appear in the June edition of the 'Proceedings of the National Academy of Sciences' online.
Researchers say REM sleep is more helpful in the creative processing than any other sleep or wake state.
They say that's because REM sleep allows the brain to make new and useful associations between unrelated ideas, and that said, enhancements aren't made due to selective memory improvements.
