Getting young children to take an hour-long nap after lunch could help them with their learning by boosting brain power, a small study suggests.
A nap appeared to help three-to-five-year-olds better remember pre-school lessons, US researchers said.
University of Massachusetts Amherst researchers studied 40 youngsters and reported their findings in Proceedings of the National Academy of Sciences. The benefit persisted in the afternoon after a nap and into the next day.
The study authors say their results suggest naps are critical for memory consolidation and early learning. When the children were allowed a siesta after lunch they performed significantly better on a visual-spatial tasks in the afternoon and the next day than when they were denied a midday snooze.
