Can’t remember? So take a nap!
Taking a nap may boost your memory and help you see the big picture and get creative!
“Not only do we need to remember to sleep, but most certainly we sleep to remember,” is how Dr. William Fishbein, a cognitive neuroscientist at the City University of New York, put it at a meeting of the Society for Neuroscience last week.
Good sleep is a casualty of our 24/7 world with few of us getting the recommended seven to eight hours a night.
Over time, a chronic lack of sleep can erode the body in ways that leave us more vulnerable to heart disease, diabetes and other illnesses.
But perhaps more common than insomnia is fragmented sleep — the easy awakening that comes with aging, or, worse, the sleep apnea that afflicts millions, who quit breathing for 30 seconds or so over and over throughout the night.
Scientists increasingly are focusing less on sleep duration and more on the quality of sleep, what’s called sleep intensity, in studying how sleep helps the brain process memories so they stick. Particularly important is “slow-wave sleep,” a period of very deep sleep that comes earlier than better-known REM sleep, or dreaming time.
Even a 12-minute nap can boost some forms of memory, adds Dr. Robert Stickgold of Harvard Medical School.
