Sleep Calories

Many variables that go into the calorie-burning equation, such as age, sex, weight, metabolism, diet, and physical and nonphysical daily habits. The two most important factors in determining how many calories you burn while sleeping are weight and number of hours slept. On average, a person burns between 0.4 and 0.5 calories per pound, per hour. For example, a 100 lb. person burns 40-50 calories per hour. In eight hours of sleep, this person will burn approximately 360 calories.

A pound of muscle burns fifty calories a day on average and a pound of fat burns nine calories. A leaner, more muscular person is going to burn up to five times more calories per pound.

If you weigh 160 pounds, you burn 69 calories per hour while sleeping, the FitWatch website calculates up to 552 calories burned during eight hours of sleep. A 120-pound person burns about 51 calories per hour sleeping, or 408 for eight hours; a 200-pound person burns 86 calories per hour, or 868 for eight hours of sleep.

Fifteen minutes of laughter a day will burn ten to forty calories, depending on a person’s weight and the intensity of the laughter.  A study by Loma Linda University found that laughing raises the levels of immunoglobulins, which ward of disease, by fourteen percent. Laughter also has other benefits, including increased pain tolerance, relief of emotional stress and a workout for the muscles of the diaphragm, abdomen, back, and shoulders.
