How Your Body Use Calories While You Sleep

Burning calories is a term most often associated with aerobic exercise and physically taxing jobs But actually you dont need to be engaged in strenuous activity to burn calories Your body uses them up around the clock even when you are asleep Learn more about the functions your body performs at night and exactly how it uses calories while you sleep
How REM Uses Energy
Despite the fact that you are resting your body still consumes energy when you sleep Energy use is particularly high during REM rapid eye movement sleep During this time your brain is highly active and you burn the most glucose your bodys source of fuel Your heart rate and blood pressure also rise during this time which burns more calories
Other Calorie Burning Activities During Sleep
During the night your body goes to work repairing any damage done on a cellular level during your waking hours For instance if you exercise during the day your muscles will recover and repair themselves at night which requires energy Food digestion also uses energy as your body breaks down your meal into usable fuel for the following day
How Many Calories Can You Burn
The amount of energy you use during sleep depends on a number of factors including your basal metabolic rate BMR which determines the amount of energy your body needs to maintain its most basic functions This includes breathing blood circulation and keeping your organs running 
How much you weigh plays a role in setting your BMR The more pounds you are carrying the more energy you use Finally the amount of sleep a person gets influences calories burned as well For example a healthy person who weighs 125 pounds burns approximately 38 calories per hour of sleep so you can multiple that number by number of sleep hours to see approximately how many calories are being burned
Building Muscle While
Building muscles while you sleep.During REM sleep the muscles relax which can help relieve tension and reduce symptoms of certain types of chronic pain In fact many of the critical restorative functions in the bodylike tissue repair and muscle growthoccur mostly or only during sleep
A consistent sleep schedule of seven to nine hours a night possibly more if you are a competitive athlete will help the muscle healing process
In addition to muscle strength muscle coordination improves with sufficient sleep Basketball players who added two hours of sleep to their nightly routine experienced a five percent increase in reaction time and speed on the court
Sleep is vital for cementing muscle recall linked to body movements Together with the muscle repair and growth that happens during sleep this allows for overall improved athletic performance
The exercise sleep connection works both ways Strength training itself can help you get a better nights rest Individuals who strength train may fall asleep faster have better quality sleep and wake up less frequently throughout the night Dont like to lift
Try running yoga or aerobics instead Any type of exercise is beneficial when it comes to sleeping more soundly although some exercises like competitive sports should be avoided within two hours of sleep
The Right Amount of Sleep
Although too little sleep has been linked to weight gain too much sleep can have a similar effect as you are expending less energy overall during the course of the day You burn more calories when you are awake and moving around than when you are at rest
In addition to getting a healthy amount of sleep you can increase the number of daily calories burned by incorporating exercise into your routine Focusing on eating smaller meals and avoiding alcohol before bed can also help with your metabolism
If you still find yourself having missing out on sleep even after practicing good sleep habits you may want to talk to your doctor about your sleep problems and to schedule a consultation with a sleep specialist
