Calorie Burning

There are many specifics of the calories burned during sleeping, but we need to understand the BMR or the basal metabolic rate which is the number of calories. The body burns during the rest time.

It slows down the process but still works towards keeping itself good. That leads to a burn in calories. Apart from that, there are various factors that affect your BMR.

  • The BMR of your body depends on the body composition. It is about the muscle tissue and fat tissue combined – we know that the muscle tissue will burn more calories than the fat tissue and hence the people who have higher muscle mass will burn more calories than others.
  • Another factor that affects the metabolism is age, and as we age, the BMR decreases, so it is pretty obvious that younger people will burn more calories.
  • There is another factor called gender that might result in the BMR fluctuations as men will burn more calories than women due to the higher muscle mass content.
  • The sleep quality also determines the PMR of the person as one with the quality of sleep, will burn more calories than people who have poor sleeping patterns. Poor sleeping patterns might also result in various other consequences like hormonal imbalance and aging.
