How Saunas Burn Calories
Saunas increase your heart rate and metabolic rate as your body works to cool itself. The calorie burn is modest compared to exercise but real and measurable. Your body expends energy maintaining core temperature, pumping blood to skin surface, and producing sweat. The burn is estimated at 1.5 to 2 times your basal metabolic rate.
Regular sauna use provides cardiovascular benefits similar to moderate exercise, including improved blood pressure, endothelial function, and heart rate variability. Finnish studies show reduced cardiovascular mortality with frequent sauna bathing.

Frequently Asked Questions
Can saunas help with weight loss?
Saunas cause temporary water weight loss through sweating, regained once you rehydrate. Actual calorie burn is modest (70-150 cal per 20 min). Saunas are best as recovery and wellness tools rather than primary weight loss methods.
How long should I stay?
15-20 minutes for beginners, up to 30 for experienced users. Stay hydrated and exit if dizzy. Finnish tradition involves multiple shorter sessions with cool-down breaks between them.
Do infrared saunas burn more?
Despite marketing claims, infrared saunas likely burn slightly fewer calories due to lower temperatures. However, they may be more comfortable for longer sessions.
