What Are the Energy Costs of an All-Nighter?

 "Staying up all night clearly taxes the body, but scientists have only now added up the exact bill. By measuring the actual number of calories the body expends to fuel an all-nighter versus a good night’s sleep, researchers from the University of Colorado at Boulder calculate that a full night of sleep helps the body conserve as much energy as is in a glass of warm milk.

Missing a night of sleep forces the body to burn about an extra 161 calories than it would have during eight hours of sleep (not counting what’s used in moving around while awake), but it’s no weight-loss miracle: The body tries to make up for the deficit by saving more energy than usual the next day and night, researchers report in the January Journal of Physiology."
