Sleep Loss Burns Calories at Both Ends, University of Colorado Study
Futurity -- U. COLORADO (US) — The metabolic cost of missing one night’s sleep is the equivalent of walking slightly less than two miles. “We found that people do expend more energy when they are awake in bed than when they are asleep,” says Kenneth Wright, associate professor of integrative physiology at the University of Colorado-Boulder, who says eight hours of sleep saves roughly 135 calories over eight hours of wakefulness.
