Not So Healthy: Catching Up On Your Sleep

Sleeping in late on the weekend to make up for winks lost during the week can actually make you feel more lethargic, according to studies done at Houston’s University of Texas. Why? "Changing your wake-up time confuses your suprachiasmatic nucleus (SCN), a cluster of brain cells that acts like a biological clock, dictating when everything from energy and strength to creativity will peak and plunge,” explains lead researcher Michael Smolensky, Ph.D., author of The Body Clock Guide To Better Health.

Smarter Strategy: Wake up at your usual weekday time, then nab a 20 minute afternoon nap or go to bed early if you’re feeling groggy. Although scientists still aren’t sure why, midday snoozes and early bedtimes do not disrupt the body’s biological clock the way sleeping in late does, according to researchers at UCLA.
