There
are 3 factors at work in a spa: heat, bouyancy and massage.
Together, they create an experience that is both relaxing
and healing. Immersion in hot water raises the body temperature
and causes the blood vessels to dilate, resulting in increased
circulation. The bouyancy of the water reduces body weight
by approximately 90%,relieving pressure on joints and muscles
and creating the relaxing sensation of weightlessness.
