How hot is an infrared sauna?
Quick answer
Infrared saunas run cooler than traditional saunas, typically 110–135°F versus 150–195°F. Infrared heats the body directly rather than the air, so the lower air temperature still produces a deep sweat. Sessions usually last 20–45 minutes, longer than a traditional sauna.
Infrared vs traditional heat
Traditional saunas heat the air to 150–195°F, while infrared saunas warm the body directly at a milder 110–135°F. Many people find the lower air temperature more tolerable for longer sessions.
Session length
Because the air is cooler, infrared sessions often run 20–45 minutes. Hydrate well, since the longer duration still produces significant sweating.
Frequently asked questions
Is an infrared sauna as effective as a traditional one?
Both produce heat exposure and sweating. Traditional saunas reach higher air temperatures; infrared achieves a deep sweat at lower temperatures over a longer session.
