Traditional indoor 212 °F · 100 °C 176 °F · 80 °C Infrared cabin 149 °F · 65 °C 113 °F · 45 °C
Infrared vs traditional: not the same heat A traditional sauna heats the air to 80–100 °C (176–212 °F): you sweat from the hot air and the steam when you throw water on the stones. An infrared sauna warms your skin and body directly while the air stays around 45–65 °C (113–149 °F).
So we never compare their temperatures head to head in the score: each is rated against the heat it is made for (194 °F / 90 °C for traditional, 149 °F / 65 °C for infrared). Most long-term research on sauna and health comes from traditional Finnish saunas.
