Have you ever wondered, “How many calories do you burn when sleeping?” While you might think the answer would be “not many,” you will be surprised to know that your body works using energy even when you are asleep. Read this post with Liftyolife (liftyolife.com) to unveil the truth.

1. How Many Calories Do You Burn When Sleeping?

How many calories do you burn when sleeping? How many calories do you burn by sleeping? As an approximate number, we burn roughly 50 calories per hour while sleeping. However, an individual burns different calories during sleep based on their basal metabolic rate (BMR). The basal metabolic rate varies depending on an individual’s age, weight, and gender. Another factor you should notice when calculating your BMR is your average daily movement. Unluckily, a one-time workout won’t offer a specific metabolic rate change in your calculation.

When falling asleep, your BMR is between 85% and 95% of your normal rate during the day. To find out “How many calories do you burn from sleeping?”, we will do some calculations below.

  • 66 + (weight x 6.2) + (height x 12.7) – (age x 6.76) = BMR for men.
  • 655.1 + (weight x 4.35) + (height x 4.7) – (age x 4.7) = BMR for women.

For example, a 27-year-old woman who weighs 135 pounds and is 6 feet 5 inches tall would burn:

655.1 + (4.35 x 135 pounds) + (4.7 x 77 inches) – (4.7 x 27 years) = 1,477 calories in 1 day at rest (or 62 calories per hour while sleeping).

2. How Many Calories Do You Burn Sleeping For 8 Hours?

Here are some average numbers for calories burned during eight hours of sleep:

  • A 30-year-old, 180 lb male burns 601 calories.
  • A 30-year-old, 110 lb female burns 406 calories.
  • A 40-year-old, 200 lb male burns 619 calories.
  • A 40-year-old, 130 lb female burns 424 calories.
  • A 50-year-old, 180 lb male burns 558 calories.
  • A 50-year-old, 110 lb female burns 376 calories.

As you can see, the figure for calories burned increases with body weight and decreases with age. Because the metabolism slows with age, it is no surprise that we see a reduction in caloric burn. A larger individual’s body will also burn more calories to function.
