Naps Improve Memory ... if You Dream
Research suggests an afternoon power nap improves memory ... if you dream. Dreaming apparently allows the brain to make connections overlooked while awake.
In the study, 99 college students memorized some information - but only half took a 90-minute nap afterwards. Nappers retained the information 10x better than their counterparts. Dreamers did, however, perform poorly on their first test. This may be because the brain knows the task in question is difficult, so it needs more attention - hence the dreaming about it.
So study the basics, then take a nap. Or, go to bed early, wake up early and review - and then take a nap.
