While the moisture on the surface of the skin evaporates and thus cools the body, a number of other changes occur in the body to release the heat as quickly as possible. The heart beats harder and faster, pumping more blood through the dilated blood vessels, thus achieving the conditioning benefits of continuous exercise.

It has been found that Infrared saunas make it possible for people who can't or who don’t do exercise conditioning, to achieve a cardiovascular training effect. It also allows for more variety in any ongoing training program. Blood flow rises from a normal five to seven quarts a minute too as many as 13 quarts a minute. Because infrared rays penetrate the body over 1-1/2 inches, there is a deep heating effect in the muscle tissue and internal organs. The body responds to this heat with a hypothalamic-induced increase in both heart volume and rate, leading to beneficial heart stress and sought-after cardiovascular training and conditioning effect. Medical research has confirmed that the use of a sauna provided cardiovascular conditioning as the body tries to cool itself.

Extensive research by NASA led to the conclusion that infrared stimulation of cardiovascular function would be an ideal way to maintain cardiovascular conditioning in American astronauts during long space flight.

Prevents Heart Disease:

A 25 to 30 minute session in our Infrared Sauna has an effect on the cardiovascular system similar to that of a six mile run. The body's natural reaction to heat is to cool itself. It does this by diverting blood from internal organs to the extremities and the skin, thus increasing the heart rate, cardiac output, and metabolic rate. Medical research indicates that use of an Infrared sauna may be as effective for cardiovascular conditioning as regular exercise. This form of exercise is most beneficial to those incapable of physical action.
