An infrared sauna is an effective means of natural therapy and prevention. Infrared light can penetrate human tissue which leads to many health benefits. In this type of sauna, the space is heated by infrared rays as the name suggests. They are built-in bodies particularly made for this purpose and reach temperatures from 40 to 60 ℃. This sauna is preferable if you are just beginning to get acquainted with saunas in general. It doesn’t heat the temperature of the air itself but rather heats the skin. The rays penetrate from 2 to 7 cm and don’t affect people with cardiac problems or those with hypertension.
