How do far infrared saunas work?
Traditional saunas raise the temperature of the air in order to warm the body – therefore what you get is a cabin of hot air. Far infrared saunas work differently, they produce the same infrared energy we get from the sun. Instead of heating the air within the cabin, far infrared saunas use over 80% of its heat energy to be directly converted to heat onto and within the body. This process is called conversion. Far infrared radiation has nothing to do with ultraviolet light, ultraviolet radiation (which causes sunburn and damage to your skin) or atomic radiation (the kind from a nuclear bomb).
