If you’re looking for ways to burn more calories, think about what you do at night. Studies show that about 20% of your resting metabolic rate, or the calories you burn when you’re not moving, comes from mental activity.
That is because while you sleep, your brain remains awake and keeps performing its function. In fact, during sleep, your brain works just as hard as when you’re awake.
So, how many calories do you use up while you sleep? It turns out that there are many things going on. In this post, we explain everything about how many calories you’re burning during sleep.
Figuring Out How Many Calories You’re Burning
A 125-pound person burns about 38 calories per hour while they sleep. That does not seem like much. When multiplied by the 7 to 9 hours of sleep recommended by experts each night, this equates to 266 to 342 calories that could be burnt while sleeping.
The number of calories burned increases as body mass increases. Therefore, a 150-pound individual could perhaps burn forty-six calories every hour, or “322” to “414” calories in one night. Similarly, an individual weighing 185 pounds may burn approximately “392” and “504” calories, or around 56 calories, during a full night of sleep.
How exactly are these numbers calculated? It all depends on how your body works. Metabolism is the process by which food is turned into energy that the body can use for daily tasks. Even things like breathing and circulation cost your body calories.
On the other hand, your basal metabolic rate (BMR), is the number of calories you burn each day when you’re not doing anything. This includes activities like sleeping and sitting.
So, to figure out your BMR, you use an equation that takes into account your weight, height, and age. For height, you use inches and for weight, you use pounds.
“BMR for men is 66 + (6.2 x weight) + (12.7 x height) – (6.76 x age).
655.1 + (4.35 x weight) + (4.7 x height) – (4.7 x age) = women’s basal metabolic rate (BMR)
For instance: A 35-year-old man who is 5 feet 11 inches tall and weighs 175 pounds would be: 66 + (6.2 x 175) + (12.7 x 71) – (6.76 x 35) = 1,816 calories”.
A 35-year-old woman who is 5 inches tall and weighs 135 pounds would burn Calories: “655.1 + (4.35 x 135) + (4.7 x 65) – (4.7 x 35) = 1,383 calories”.
Additionally, when you rest, sleep and do other things, you’ll burn more calories if your body has more mass. Because men tend to have more muscle mass than women of the same weight, men tend to burn more calories at rest.
Factors That Impact Sleep Burn?
Even if you are a literal boss all night, running in your dreams will not cause you to burn more calories during sleep.
If you wish to increase your BMR, you can increase your metabolism through healthy nutrition and exercise. This will also lead your body to burn more calories constantly, whether you’re daydreaming or jogging around the neighborhood.
Here are some additional factors that can alter your metabolism and sleep burn.
1. Late-night snacks
There’s nothing better than pizza at midnight, right? You may have heard that eating before night will decrease your metabolism, however, this is not supported by scientific evidence.
In fact, midnight cravings might temporarily increase your metabolism through a process known as thermogenesis. It is a process that dissipates energy as heat after you eat.
Concern yourself less with when you eat and more with what you eat. Snacking frequently during the day can result in weight gain and a slowed metabolism.
2. Muscle gains
The greater your muscle mass, the more calories you will burn. Therefore, incorporating everyday exercise, particularly strength training, can cause you to burn more calories when sleeping (and while hitting snooze… 10 times).
3. Beware of supplements that raise your metabolic rate
Let’s face it: weight loss supplements and anything else claiming to increase your metabolism might be shady as hell.
They are certainly not all awful, but many involve dangerous substances and questionable claims. To reduce weight, you may wish to try a natural appetite suppressor and keep to your regular exercise and nutritious diet. However, consult with your doctor before taking any supplement.
4. Drinking Coffee After Coffee
Study indicates that caffeine provides a short mini-boost to your metabolism that may last into your sleeping hours.
But hold off on the Red Bulls and cappuccinos for now. There has not been enough research conducted to confirm that caffeine has a long-term effect on weight loss.
5. Not Enough Sleep
If you cannot sleep Whether due to work strain, sleeplessness, or late-night Netflix marathons, a study indicates poor rest can lead to an increase in cortisol levels .
Cortisol causes the body to retain excess fat, increases hunger (and irritability), and slows the metabolism. In addition, according to a 2017 study, longer sleep duration is related to a lower BMI and improved metabolic profiles .
6. Certain Health Problems
Certain disorders, such as Cushing syndrome, and hypothyroidism can reduce the metabolism. In these conditions, even with a good diet and regular exercise, one can lead to weight gain and a slower calorie burn.
So, consult your physician if you suspect you have a problem that affects your metabolism. They can
