Are the lower temperatures in an infrared sauna still effective?

The cabin air temperature in a far infrared sauna plays a supporting role.

The cabin air temperature in a traditional sauna is the driving force.

Since far infrared saunas heat the body directly, the light energy penetrates the body much more deeply that hot air heat. The infrared heat in your personal infrared sauna is able to raise the core temperature of the body more effectively than hot air. 

By raising the core temperature, far infrared saunas will produce double or triple the amount of sweat volume as traditional saunas.

Far infrared sauna heat is thought to be seven times more effective at detoxifying metals such as mercury and aluminum, nicotine, alcohol, ammonia, sulfuric acid and other environmental toxins, as well as cholesterol when compared to the hot air heat of hot rock and steam saunas.
