Hogy mennyit vagyunk ébren, az befolyásolja a napi kalória bevitelünket?

Na erről még nem hallottam.

De egy gyors guglizásnak pomt az lett az eredménye, hogy elvileg a több alvás égeti a több kalóriát.

"The metabolic rate is down-regulated with less sleep. Translation: When you sleep less, your body starts to burn calories at a slower rate to preserve energy. In the study, people burned on average 400 more calories by sleeping for 3 more hours--that's an additional 2,800 calories burned in just one week"

Have you ever wondered how many calories you burn while sleeping? While you may think the answer would be “not many,” you might be surprised to learn that your body is at work using energy even when you’re at rest.

How many calories you burn has to do with various factors, including your weight, your metabolism, and how much sleep you get each night.

Determining how many calories you burn

A person who weighs 125 pounds burns approximately 38 calories per hour sleeping. That doesn’t necessarily sound like a lot. But multiply that by the recommended seven to nine hours of sleep experts say you should get each night, and that’s a total potential of 266 to 342 calories for snoozing.

The amount of calories burned increases according to body weight. So, a person who weighs 150 pounds might burn 46 calories an hour or between 322 and 414 calories a night. And a person who weighs 185 pounds might burn around 56 calories or between 392 and 504 calories for a full night of sleep.

How are these numbers calculated exactly? It’s all about your individual metabolism. Metabolism is a process by which the body converts food into energy for use in daily activities. Even keeping your organs running, breathing, and circulating blood costs your body calories. Your basal metabolic rate (BMR), on the other hand, represents the number of calories you individually burn a day at rest, or while you’re sedentary. This includes sleeping and sitting.

To calculate your BMR, you use an equation that factors in your sex, weight, and age using inches for height and pounds for weight.

66 + (6.2 x weight) + (12.7 x height) - (6.76 x age) = BMR for men

655.1 + (4.35 x weight) + (4.7 x height) - (4.7 x age) = BMR for women

For example: A 35-year-old man who weighs 175 pounds and is 5 feet 11 inches tall would be:

66 + (6.2 x 175) + (12.7 x 71) - (6.76 x 35) = 1,816 calories.

A 35-year-old woman who weighs 135 pounds and is 5 feet, 5 inches tall would be:

655.1 + (4.35 x 135) + (4.7 x 65) - (4.7 x 35) = 1,383 calories.

The more mass your body has, the more calories you’ll burn while resting, sleeping, and doing other activities. Men tend to burn more calories at rest than women of the same weight because men typically have higher muscle mass. Muscle burns more calories at rest than fat does.

Factors that affect how many calories you burn

Want to maximize your calorie torching in the overnight hours? A recent study uncovered that if you skip an entire night of sleep, you may actually burn an extra 135 calories over that period of time. Some participants burned as many as an extra 160 calories. But before you toss your pillow, understand that skipping sleep isn’t a great way to lose weight.

Sleep loss over time may contribute to weight gain and obesity. It elevates certain hormone levels in the body, like cortisol. This hormone makes you hold onto extra fat. Not only that, but it may also increase your appetite and lead to a slower metabolism."
