Scientist from the University of California, Berkeley, announced today that short naps may be more effective than long night sleep. During a power nap the brain clears old memories and gets ready to proccess new information and experience.
Matthew walker from Berkely said today during a brief press confrence at a meeting of the American Association for the Advancement Science in San Diego: "Sleep prepares the brain like a dry sponge, ready to soak up new information." He also mentioned that it is more important to sleep before learning than after.
Scientists have found out that during sleep, information gathered in short-term storage in hippocampus moves to the cortex of brain, where long-term memories are collected. This happens mostly during stage 2 non-REM (rapid eye movement) sleep.
Scientists made an experiment on power naps. They asked 39 young people to learn some facts. One group took a 90-minute nap before the exercise, and the other didn't. The first one achieved much better results.
This discovery is important, because it shows the power of sleep and that it is essential for good performance. But the news also revealed the power of short naps, which may be very helpful for many people.
