Brains need a nap plan

-

AFTERNOON naps are good for the brain, as long as they don’t last too long.

Based on two years of data from 3000 people aged 65 and over, researcher­s found those who napped for less than 90 minutes a day performed better on cognitive and memory tests.

The worst performers were those who napped for longer than this, according to the study by the Center for Sleep and Circadian Neurobiolo­gy at the University of Pennsylvan­ia.

One theory is the longer the nap, the greater the likelihood of going into deeper sleep, which can leave people groggy.
