A nap in the afternoon can boost brain power
AN HOUR'S nap in the afternoon can boost a person's brain power and improve their memory, according to a study showing that short periods of sleep during the day can make it easier to function mentally.
Scientists found that a Spanish-style siesta after lunch does more than just refresh the body and mind, it also makes it easier for the brain to store and retrieve items of short-term information needed for working or studying.
The findings lend weight to the idea that sleep not only restores a person's sense of well-being, but is essential if the brain is to take on additional information as part of the memory-forming process of learning.
"Sleep not only rights the wrong of prolonged wakefulness but, at a neuro-cognitive level, it moves you beyond where you were before you took a nap," said Matthew Walker, a psychologist at the University of California Berkeley, in America. (© Independent News Service)
