Does Sauna Burn Calories?

Does Sauna Burn Calories? Yes, saunas do burn calories – your body works hard to regulate temperature, which spikes your heart rate and metabolism. Whether you’re chasing weight loss or long-term wellness, regular sauna use helps your body torch calories in a passive, restorative way.

Does Sauna Burn Calories While Sitting Still?

Absolutely. Even without moving, your body is in active recovery mode.

Thermogenic effect mimics low-intensity cardio
Sessions at 80–90°C can burn 200–300 calories
Increases your basal metabolic rate (BMR) – the calories your body burns at rest

That means over time, regular sauna use could help you burn more calories daily, even outside the sauna.

Sauna vs. Exercise for Weight Loss

Let’s not get it twisted – the sauna isn’t a replacement for training or eating right.

To lose weight, the maths is simple: calories in < calories out
Sauna use supports this by increasing your BMR
But you still need to watch calorie intake and stay active

Use it as a boost, not your only strategy.
