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.

Questions

Where does the data come from?

From the makers’ product pages and spec sheets, and from independent reviews when a maker publishes nothing. Every sauna page lists its sources. A figure nobody publishes is marked “not published”: we never guess it.

Is an infrared sauna as good as a traditional sauna?

It is a different heat. A traditional sauna heats the air to 80–100 °C (176–212 °F) and lets you throw water on the stones. An infrared sauna warms your body directly at 45–65 °C (113–149 °F) air. Most of the long-term research (Finnish cohorts) was done in traditional saunas.

Do you earn money from these links?

No. No affiliation, no sponsorship: the links go to the makers’ sites and nobody paid to be in this comparison.
