ITHACA, N.Y. (AP) - A psychology professor at New York's Cornell University says it's a good day for a nap.
James Maas says the one-hour loss of sleep at the start of daylight saving time can bring a lack of focus. He says it usually takes about four or five days for the body's sleep clock to adjust.
Maas says he invented the term "power nap" -- and he says the perfect nap would last no more than 15 minutes, as long as it doesn't send you into a deep sleep, which makes you groggy when you wake up.
Another suggestion for coping with the time change is to expose yourself to light as soon as you wake up.
