I remember debating with a friend about the temperature of the dry sauna. As I enter the dry sauna and check the temperature, it reads 88 °C. The room is quiet, not a single sound and just rushing warm air builds up of an immediate sweat. When you lounge in a sweat bath, heat sensitive nerve endings produce a chemical which alerts millions of sweat glands embedded in skin. One of its chief functions is to cool the body by evaporation.

The sweat in a dry sauna draws out lactic acid which causes stiff muscles and contributes to general fatigue. Sweat flushes out toxic metals such as copper, lead, zinc and mercury which the body absorbs. The heart is pressed into a faster pace to keep up with the additional demands for blood. Impurities in the liver, kidneys, stomach, muscles, brain, and most other organs are flushed out by the faster flow of juices.
