Infrared vs traditional sauna: what is the difference?

Infrared saunas and traditional Finnish saunas compared: how they heat, how hot they get, what a session is like and which kind of public venue offers each.

Both make you sweat. They get there differently, and the experience in a public venue is quite different too.

How they heat

A traditional sauna heats the air with a stove (electric, wood or gas), often over a pile of rocks. You can ladle water on the rocks for a burst of steam. An infrared sauna uses panels that emit infrared light, which warms your skin directly while the air stays cooler.

How hot

Finnish-style saunas typically run at about 176 to 212 F (80 to 100 C) with low humidity, per the Mayo Clinic Proceedings review ^[1]; US public saunas often run a little cooler. Infrared cabins usually run far lower, around 110 to 150 F, which many first-timers find easier to sit in for longer.

What a session is like

	Traditional	Infrared
Typical venue	Public sauna, bathhouse, banya, social sauna club	Infrared studio with private suites
Shared or private	Usually shared	Usually private
Steam	Yes, from water on the stones	No
Booking	Drop-in, timed session or membership	Timed session by booking
Extras	Cold plunge, showers, rest areas	Red-light panels, shower, sometimes a plunge

Health claims

Most of the long-term research on sauna bathing comes from Finnish, traditional saunas, such as the Finnish population studies summarized in the Mayo Clinic Proceedings review ^[1]. Those results do not automatically carry over to infrared cabins, which run cooler. Treat bold health claims for either kind with care.

Which to pick

Want the social, steamy, hot-then-cold ritual? Look for a traditional sauna, a bathhouse or a banya. Want a private, quieter, lower-temperature sweat on a lunch break? An infrared studio fits better.
