Quick answer
A sauna raises resting metabolism by roughly 1.5–2×, so a 30-minute session burns about 60–120 extra calories — mostly water weight, not fat.
kcal = BMR/min × multiplier × minutes

Frequently asked questions
Do you burn fat in a sauna?
Barely — the weight you lose is sweat. The real benefits are recovery, circulation and cardiovascular conditioning.
How much water should I drink after a sauna?
About 16–24 fl oz per pound of weight lost, ideally with electrolytes after long sessions.
