A brief nap could boost people's memory, according to new research.
Researchers at The City University of New York found that having a
brief sleep improved people's ability to remember things.
Volunteers were told to memorise pairs of words. When they were tested
straight afterwards and six hours later, those who had been allowed a nap
of up to one hour before the retest achieved 15 percent higher scores than
the volunteers who had not been allowed to go to sleep.
The researchers told New Scientist magazine:
"Traditionally, time devoted to daytime napping has been considered counterproductive
But they added that it now seemed that sleep was "an important
mechanism for memory formation".
The study was published in the journal Neurobiology of Learning and
Memory, the magazine said.
