Activities do not have to be aerobic or muscle-strengthening to melt calories, although pulse-elevating exertion is recommended for optimum health benefits. One unexpected calorie-burning activity is sleeping.

Sleep Recommendations

According to the National Sleep Foundation, "sleep needs vary across ages and are especially impacted by lifestyle and health." Even though a precise amount of sleep cannot be pinpointed, the foundation offers a standard adhered to by most sleep experts of 8.5 to 9.25 hours for teens aged 10 to 17, and seven to nine hours for adults 18 and older.

Calories Burned While Sleeping

The caloric benefits of any activity vary, depending on your body mass and the frequency, intensity and duration of the activity. If weight loss is your goal, remember that 3,500 calories equals approximately 1 pound of fat. You should burn 3,500 calories more than you take in, regardless of type or intensity of physical activity, to take off 1 pound. You cannot expect to burn a large amount of calories while sleeping. If you sleep seven hours a day and weigh 110 pounds, you can expect to burn approximately 314.3 calories, according to Discovery Health. If you weigh 150 pounds or 200 pounds, you will work off an estimated 428.6 calories or 571.4 calories, respectively, in that same seven-hour stretch. A one-hour nap will recharge a 125-pound person while taking off 51 calories. For a 175-pound individual, 60 minutes will burn an estimated 71.4 calories.


Though you would not be able to count sleep toward your 150 minutes of recommended weekly moderate-intensity aerobic activity, sleeping for the recommended amount every day bolsters overall health and can enhance weight-loss and weight-maintenance regimens.
