How Many Calories Do You Burn Sleeping?
Quick Answer: You burn approximately 40-80 calories per hour while sleeping, or 300-500 calories per 8-hour sleep depending on your body weight.
Even at rest, your body burns calories to maintain vital functions like breathing, circulating blood, cell repair, and brain activity. This is called your Basal Metabolic Rate (BMR).
Factors Affecting Calories Burned During Sleep
- Body weight: Heavier people burn more calories at rest
- Age: Metabolism slows with age
- Sleep quality: Deep sleep phases burn more calories
- Room temperature: Cold rooms may slightly increase calorie burn
