Want to get more done? Go lay down and have a nap for an hour or so every day. Research indicates that during a cognitive test, the people who snoozed during the day generally out-performed those who did not.
In our frenetic world, this seems upside down. But resting the brain will ultimately allow it to perform better than it would if you just kept on slogging.
The theory is that when a person naps, their short-term memories are being processed and moved from temporary storage in the brain's hippocampus to long-term storage in the pre-frontal cortex.
"Dr. Matthew Walker, lead author of the study, explained the situation in terms of an e-mail inbox that becomes full. Until a person sleeps, or takes a nap, all the new information received since the last sleeping period remains in hippocampus. Once it is full, no new information can be readily processed, inhibiting that person from fully functioning throughout the entire day."
