For that sought after healthy glow, FIR Sauna heat therapy allows increased blood circulation to carry great amounts of nutrients to the skin, thus promoting healthy tone and texture. A FIR Sauna heat bath also provides a mild cleansing of the skin.
For injuries, FIR generated heat stimulates vasodilatation of peripheral blood vessels, bringing oxygen to joints and extremities, speeding the healing of sprains and strains, thus relieving pain and reducing the time it takes the human body to recover from an injury.
FIR Sauna heat therapy can aid in weight loss by speeding up the metabolic process of vital organs and endocrine glands resulting in substantial caloric loss in a sauna heat session. The sweat that is generated from a sauna is all part of a "Thermoregulatory" process that increases your heart rate, metabolic rate and your cardiac output. The blood vessels dilate allowing the heated blood internally to cool at he skin's surface. This process requires a large amount of energy, which according to Guyton's Textbook of Medical Physiology - producing one gram of sweat requires 0.586 kcal. The Journal of American Medical Association States" A moderately conditioned person can easily sweat off 500 grams in a sauna, consuming nearly 300 kcal, which is equivalent to running 2-3 miles. A heat-conditioned person can easily sweat off 600-800 kcal with no adverse effects. While the weight of the water loss can be regained by drinking water, the calories will not be.”
