“Lack of rest at any age is going to make you feel old,” says Michael Vitiello, associate director of the Sleep and Aging Research Program at the University of Washington is Seattle. Fatigue makes you physically slow and mentally dull. How much sleep as how good you feel during the day as a result,” says Vitiello. “If you always feel draggy in the morning or late afternoon, you probably need more time in bed.” To rest best, he advises turning in and getting up at the same times every day in order to keep your body clock in sync.
