Oddly enough, there is not much documented on water immersion, however, in the early years of America's manned space program, the National Aeronautics and Space Administration (NASA) became concerned about astronauts because of the illness and dizziness they suffered during relatively short periods in space. A loss of salt and minerals (electrolytes) can cause this condition and the agency realized that before longer space travel could be considered, a solution has to be found. Warm water immersion (soaking in a spa) was selected for the NASA experiments, because you weigh 10 percent of your body weight in water, and that is as close as they could come to simulating weightlessness of space here on earth.

Hormones triggered the electrolyte changes they discovered and NASA found a means to control hormones. This work was helpful in finding out why soaking in hot water makes you feel so good.

While you're relaxing away in your Spa, little do you know that the warm water is actually hard at work healing your tired body. The natural effects of swirling warm waters increase circulation, relax joints and tired muscles and relieve pain associated with muscle fatigue. The use of a spa has been endorsed by the National Arthritis Foundation as a treatment for arthritis and its symptoms.
