The answer to that question is yes. Using the BMR to calculate how many calories the body burns during sleep can be achieved by using the following formula:. Both are linked to specific brain waves. During the night you cycle through all stages of non-REM and REM sleep several times with increasingly longer periods of deep REM sleep happening as morning approaches. REM sleep initially tales place about 90 minutes after falling asleep. Your eyes move rapidly from side to side behind closed eye lids — hence the name.
Breathing becomes fast and irregular as your heart rate and blood pressure increase. Most dreaming also happens during REM sleep. And night-time calorie burn is actually dependant on REM. Body fuel or glucose is continually being manufactured during sleeping hours — and getting plenty of REM sleep will burn the optimum number of calories.
Poor sleep results in raised levels of the hunger hormone and lower levels of leptin. As well as for growth, learning, and memory.
Sleeping less than five hours a night can potentially increase your weight. And sleep loss over time can contribute to obesity.
Multiply that by the number of hours slept. And there you have it — calories burned while sleeping. Examining some average numbers can be a good place to start. Consider these examples for calories burned during eight hours of sleep:. As you can see, the amount of calories burned decreases with age and increases with body weight.
Metabolism slows with age, so it comes as no surprise that we see a decrease in caloric burn. As it turns out, there are a few ways to increase your calorie burn while you sleep. This is when your brain is most active and burns the most calories. More REM sleep can lead to burning extra calories while you sleep. Here are a few tips to improve sleep quality:. Another way to burn more calories during sleep is to turn down the thermostat or sleep in light pajamas.
Cooler temperatures will force your body to work a little harder to stay warm. In a study led by Dr. Francesco Celi of Virginia Commonwealth University, a group of five healthy male subjects slept in rooms of varying temperatures for one month each.
Exercise is important to maintaining healthy body weight, and it can improve your sleep quality. A Cleveland study examined men and women between the ages of 67 and 96 and 70 and 99, respectively.
Compared to those who slept between seven and eight hours each night, men who slept less than five hours were nearly four times more likely to be obese. Women who slept less than five hours each night were more than twice as likely to be obese as their well-rested counterparts. Short sleep length was also associated with increased body fat. Plus, people who are chronically sleep-deprived are more likely to be overweight, have cardiovascular disease, strokes, infections, and even some types of cancer compared to those who get enough sleep.
Consult your healthcare provider if you have persistent sleep deprivation. They may recommend a polysomnogram or sleep study. It will collect data like your oxygen levels, breathing, limb, and eye movements. These results can help doctors develop a treatment plan or suggest further testing. The number of calories your body needs daily depends on your age, biological gender, and average lifestyle activity.
Women who work desk jobs and exercise very little usually burn 1, calories per day. On the other hand, men who lead sedentary lifestyles and exercise minimally usually burn around 2, calories per day.
But even things as little as tapping your toes can burn calories. The best way to naturally burn calories? BMR varies depending on mass, height, and age you can determine yours with this calculator , but on average, this has been found to be about 45 calories per hour.
So if you can find an average caloric expenditure for an individual at rest e. Your body burns the most calories during deep REM sleep, when your brain is most active because it requires the most oxygen to function.
And likewise, metabolic activity also cycles throughout the night. Our brains are just as active or even more active during REM sleep, as they are while we are awake," says Wells. If you're truly looking to maximize the amount of calories you burn during sleep, turn the room temperature down: according to the American Academy of Sleep Medicine, you should aim to sleep in a room that is between 60 and 67 degrees Fahrenheit.
You should also be sure to get enough sleep, as sleep deprivation can negatively affect your overall metabolism. And this can lead you to start packing on the pounds: a study found that men who slept 5 or less hours a night were almost 4 times more likely to be obese. Sleep deprivation has also been found to mess with the hormones leptin and ghrelin , increasing feelings of hunger.
