Visiting saunas for relaxation and detoxification is an age-old tradition. Throughout history and across cultures, and particularly in Scandinavia and Finland (the word sauna is an ancient Finnish word), people have sought healing through heat.
Far Infrared Sauna
In a traditional sauna, heated rocks or steam are used to heat the air, which in turn heats you. Far infrared saunas work differently: The infrared heater emits light, which is experienced as heat. “Far” describes where the infrared waves fall on the light spectrum, and this radiant heat is experienced directly, i.e. from the inside out rather than the outside in.
Like spending time in the warm sun, infrared heat is experienced as a soft, gentle, relaxing heat. But unlike the sun, spending time in a far infrared sauna will never cause your skin to burn.
The high temperature of a sauna causes vigorous sweating and increased heart rate, producing an effect similar to the physiological response elicited by moderate exercise. When core temperature and heart rate are elevated the body is forced to work hard to bring the system back into balance. After just a few minutes in the sauna, soon after you begin to sweat, your blood vessels dilate and circulation improves, cardiovascular function and metabolism are boosted, endorphins are produced, and your immune response is stimulated.
