The recommended temperature range for infrared sauna sessions is 120-150 Fahrenheit degrees (approximately 45 - 70 Celsius) . Infrared heat is a different type of heat than traditional wet or dry saunas, so while you do sweat you don’t feel as hot as you might in a traditional sauna. If you have concerns about getting too hot, start out at the low end – 120 Fahrenheit degrees – and adjust upwards from there based on your comfort level. You have full control over the temperature while you’re in the sauna.
