At the end of a half an hour session, the temperature will be around 120-125 degrees. The starting temperature that we recommend for getting in the sauna is 110 degrees.
The most difficult concept for people new to infrared saunas to understand is that an infrared sauna does not use hot air to produce a sweat. Rather, it uses invisible light on the far infrared spectrum that comes off as radiant heat.
The invisible light, or infrared light, travels the same way that light does—in a straight line, and then penetrates into your skin and is absorbed raising your core body temperature from the inside. Have you ever been cold in the shade or inside your home then walked outside into the sunlight and felt that internal warmth radiating through your body? That is far infrared radiant heat! When you are in the sauna you are slowly raising your core body temperature over the span of your sauna session. In the meantime, your core body temperature will have risen a few degrees producing a sweat that excretes toxins and heavy metals.
