Why Is Sauna Used In Cancer Therapy?Sauna Therapy Used in Cancer Therapy.This is a new and experimental procedure. It shows a great promise in some cases when used properly. American researchers favor careful monitoring of the tumor temperature; whereas, the successes reported in Japan make no mention of such precaution. Infrared healing is now becoming the leading edge in the care of soft tissue injuries to promote both relief in chronic or intractable "permanent" cases, and accelerated healing in newer injuries.Localized infrared therapy using lamps tuned to the 2 ~ 25 micron waveband is used for the treatment and relief of pain by over 40 reputable Chinese Medical Institutes.Give Your Entire Body A Workout!The oxygen needs of the body increase by about 20 percent so the lungs, another important eliminator of body wastes, join in the body's quickened pace. (The lungs' rapid exchange of carbon dioxide for oxygen is hindered in some sweat baths. In high humidity water condenses on the tiny alveoli where this exchange takes place and breathing may be slightly more difficult. On the other hand, if the air is too dry, as occurs in many American saunas, mucous membranes may become dry and damaged.) Clogged respiratory passages are opened by heat, giving relief from colds and other minor respiratory problems. Sweat bathing is not recommended for those suffering from pneumonia or other acute respiratory diseases. (see Sauna)Understanding Infra-Red SaunaRadiant heat is simply a form of energy that heats objects directly through a process called conversion, without having to heat the air in between. Radiant heat is also called Infrared Energy (IR). The infrared segment of the electromagnetic spectrum is divided into 3 segments by wavelength, measured in microns or micrometers (a micron = 1/1,000,000 of a meter); 0.076 ~ 1.5 microns = near or close; 1.5 ~ 5.6 = middle or intermediate; 5.6 ~ 1,000 = far or long wave infrared. The infrared segment of the electromagnetic spectrum occurs just below or ¡°infra¡± to red light as the next lowest energy band of light. We can, however, feel this type of light that we perceive as heat. Our sun produces most of its energy output in the infrared segment of the spectrum.After A Sauna SessionWhen the bocly is slowly cooled, the effects of heat are reversed--the heart calms, sweat pores close, dilated blood vessels contract and body temperature returns to normal. The German Sauna Society recommends a warm foot bath to re-open closed blood vessels.On the other hand, abrupt cooling brought on by a plunge into snow or icy water creates a more dramatic effect. For this reason, people with weak constitutions should avoid rapid cooling. Vessels near the skin's surface contract, but since the skin's metabolism returns to normal slower than the circulatory system, wastes accumulate that are normally washed out by the blood.For more comprehensive information on the sauna benefits
