Restores Brain Power
Napping for just an hour in the middle of the day helps refresh the body and restores brain power as well, according to a new study from the University of California, Berkeley. Not surprisingly, the inverse is true - lack of sleep causes the brain to become sluggish and unable to store new information. Researchers found that sleep deprivation reduces the ability to learn new facts by about 40 percent. Said Matthew Walker, assistant professor of psychology at UC Berkeley and the study’s lead investigator, "Sleep not only rights the wrong of prolonged wakefulness but, at a neurocognitive level, it moves you beyond where you were before you took a nap." Further research will study shorter sleep times among the aging and the possible link to neurodegenerative conditions such as Alzheimer’s.
