Are you better to get enough sleep to help you lose weight or would that time be better spent in the gym?
“The advice: 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.”
Stay out of the sun to protect your skin or get sun for Vitamin D:
“The advice: For your body to make enough vitamin D using the sun alone, you’d need strong, direct sunlight on most of your bare skin for at least 15 minutes. That’s not worth the risk of UV damage and skin cancer, says Ellen Marmur, MD, vice chair of cosmetic and dermatologic surgery at the Mount Sinai Medical Center in New York, especially since melanoma has more than doubled among women in the past 30 years. Even when you carefully protect your skin from the sun, you’ll still most likely absorb UV rays through your scalp, or from the light that gets reflected from the ground and finds its way under your sun hat or beach umbrella. If you’re concerned about your vitamin D levels, Marmur recommends asking your doctor for a blood test and making up for deficits by consuming more swordfish, salmon, vitamin D-fortified milk or OJ, and by taking supplements.”
