Thanks to deep penetration, over 4 cm into the body, of infrared rays given by infrared equipment, a heating effect occurs deep inside the muscle tissues as well as in our organs. The body reacts to this deep warming effect via the hypothalamus induced increase in both heart volume and heart rate. This favorable cardiac stress provides a sought-after cardiovascular training and conditioning effect. Medical researchers confirm that using heat penetration provides cardiovascular training as the body works to cool itself and this results in a massive increase in heart rate, cardiac output and metabolism. In confirmation of the validity of this form of cardiovascular training, NASA conducted extensive research in the early 1980s that led to the conclusion that infrared stimulation of cardiovascular function should be the ideal way to maintain cardiovascular fitness in American astronauts during long space flights. Blood circulation has been reported to increase when experiencing hypothermia (abnormally low body temperature), from the normal 5 – 7 liters per minute to as much as 13 liters per minute.
The infrared heating system enables people in wheelchairs, or those otherwise unable to move, or those who cannot follow an exercise or cardio training program, to achieve a cardiovascular training effect. This also allows for greater variety in an ongoing exercise program. “Many of us who run do it to train our cardiovascular system, not to build big leg muscles. Regular use of infrared penetration can put a similar strain on our cardiovascular system and regular use can be just as effective, in terms of cardiovascular exercise and calorie burning, as regular exercise.” - Journal of the American Medical Association 8/7/81.
