Sauna and Weight Loss: Separating Fact from Fiction

The Sauna Myth: Calories Burned

One of the most common misconceptions about saunas is that they can help you burn a significant number of calories, leading to weight loss. While it's true that you do burn calories while sitting in a sauna, the amount is relatively modest. In fact, the calorie burn from a sauna session is comparable to that of a leisurely walk.

To put it into perspective, a 30-minute sauna session may help you burn approximately 150-200 calories, depending on factors like your age, weight, and the temperature of the sauna. While this calorie burn can contribute to your overall energy expenditure, it's not a miracle solution for weight loss.

The Sauna Truth: Water Weight Loss

The weight you lose during a sauna session is primarily due to water loss through sweat, not fat loss. As your body sweats, you shed excess fluids, which can temporarily reduce your weight on the scale. However, this weight loss is temporary, and you will regain it as soon as you rehydrate.

It's essential to understand that losing water weight does not equate to losing fat. Sauna-induced weight loss doesn't target body fat stores, so it won't lead to long-term weight reduction or significant changes in body composition.

The Sauna and Weight Loss Connection

While saunas alone are not a magic solution for weight loss, they can play a complementary role in a healthy lifestyle. Here's how:

  1. Stress Reduction: Saunas, such as those offered by Thermolab, promote relaxation and stress relief, which can indirectly support weight management. High stress levels can lead to emotional eating and poor food choices, so reducing stress through sauna sessions may help you make healthier decisions.

  2. Improved Circulation: Thermolab saunas, in particular, are designed for optimal heat distribution, enhancing blood circulation during sessions. Improved circulation may indirectly contribute to a more active lifestyle and better fitness results.

  3. Detoxification: While the idea of "detoxing" is often overhyped, saunas can aid in the removal of toxins and metabolic waste through sweat. A cleaner body may function more efficiently, potentially benefiting your overall well-being.


Saunas, including those from Thermolab, can offer various health benefits, but they are not a magic solution for weight loss. The calories burned during a sauna session are relatively minimal, and the weight lost is primarily water weight, which is quickly regained upon rehydration.

To achieve meaningful and sustainable weight loss, it's essential to focus on a balanced diet and regular exercise. If you enjoy Thermolab saunas for their relaxation and other health benefits, that's perfectly fine, but don't rely on them as a primary strategy for shedding pounds. Instead, view saunas as a complementary addition to a healthy lifestyle aimed at achieving your weight management goals.
