4. Intensity (MET) = 1.5

6. Calories burned = 35kcal

Did we solve your problem today?

A sauna raises your heart rate slightly, burning a small number of extra calories.

The math behind it

calories = MET × weight × hours. Sitting in a sauna is roughly 1.5 MET.

70 kg for 20 min at 1.5 MET → about 35 kcal.

Does the weight I lose stay off?

No — most sauna weight loss is water that returns when you rehydrate.
