Detailed explanation-1: -It is believed that during normal sleep the metabolic rate reduces by around 15% and reaches a minimum in the morning in a standard circadian pattern [8, 9]. Only a 15% reduction in metabolic rate appears counter-intuitive considering the prolonged state of physical inactivity.

Detailed explanation-2: -Sleep also affects individual metabolism. Getting sufficient, high-quality rest can help your body maintain its optimal metabolic rate for your age, make it easier to lose weight (and keep from gaining weight), and help reduce risks for diseases associated with weight gain.

Detailed explanation-3: -You burn more calories awake in bed compared to being asleep. It’s thought your basal metabolic rate, the amount of calories you burn just to do basic functions, is 15% lower when asleep than when awake resting.
