When you get in HEALTH SAUNA, first you will feel pleasant dry heat.
You will also notice a great sense of relaxation and revitalization. Far-Infrared (FIR) heat is a form of naturally occurring energy that directly heats objects by gentle infrared radiation heat, rather than by raising the temperature of the surrounding air.

FIR heat is completely safe for the human body. The far infrared rays used for HEALTH SAUNA are the same as used by medical doctors or therapists for the treatment of muscle pains, joint pains or injury, rheumatism, or other chronic diseases. Far infrared radiant energy directly penetrates the body's tissues to a depth of 2" and stimulates the tissues to revitalize them. When Far infrared rays penetrate the skin, they come into contact with protein, collagen and fats, by stimulating micro-vibrations; far infra-red causes a thermal reaction which elevates tissue temperature to promote sweating endlessly. Such "pleasant and comfortable sweating" is the first step of health care.
