Sleep vs. Exercise
If one more person reminds us of the connection between inadequate sleep and weight gain, we're going to slug them with a pillow. Equally frustrating is the fact that fitness pros, including Bob Greene
, advise getting our recommended 30 minutes of exercise out of the way first thing in the morning, at the same time that we think we should be making up for our sleep deficits. So if we have only one free hour in our day, where should we spend it—in bed, or in spin class?
Sam Sugar, MD, says this comes up all the time at the Pritikin Longevity Center & Spa
, where he's the director of sleep services, and where twice-daily exercise is part of the program. Sugar points out that the scientific literature is extremely clear about the dangers of sleep loss. "Even one night of short-changed sleep can be bad for your health," he says, and excessive sleeplessness can result in increases in blood pressure, cholesterol and blood sugar—as well as weight gain. Missing one or even two workouts doesn't have the same magnitude of negative effects. At the minimum, Sugar recommends getting six and a half to eight hours of sleep every
night, while squeezing in exercise at least three times a week.
