Sleeping Calories Burn Calculator Online

The sleeping calories burn calculator is a tool designed to estimate the number of calories you burn while you are asleep. This calculation is based on your Basal Metabolic Rate (BMR), the duration of your sleep, and the metabolic equivalent (MET) of sleeping. The MET value for sleeping is around 0.9, indicating a slower metabolic rate compared to when you are awake but still active.

Formula of Sleeping Calories Burn Calculator

To estimate the calories burned during sleep, use the following formula:

Calories burned = BMR * hours slept * MET

Components explained:

• BMR (Basal Metabolic Rate): The number of calories your body needs to perform basic life-sustaining functions like breathing and circulation.
• Hours slept: The total duration of sleep in hours.
• MET (Metabolic Equivalent of Task): For sleeping, it is typically 0.9.

BMR calculation:

• For men: BMR = 88.362 + (13.397 * weight in kg) + (4.799 * height in cm) – (5.677 * age in years)
• For women: BMR = 447.593 + (9.247 * weight in kg) + (3.098 * height in cm) – (4.330 * age in years)

MET values:

• Sleeping: 0.9
• Resting: 1.0

Useful Table for Quick Reference

Below is a table for quick reference that provides estimated calories burned during sleep for various profiles without needing to perform calculations each time:

Gender	Weight (kg)	Height (cm)	Age (years)	Calories Burned (approx.)
Male	70	175	25	632
Male	85	180	40	681
Female	60	165	30	492
Female	75	170	50	536

Example of Sleeping Calories Burn Calculator

Consider a 30-year-old female, weighing 60 kg and 170 cm tall, sleeping for 7 hours. Using the provided formulas and MET values, the calculator would estimate the calories burned as follows: Calories burned = (447.593 + (9.247 * 60) + (3.098 * 170) – (4.330 * 30)) * 7 * 0.9 = Estimated Calories
