Heat and Buoyancy Benefits
Enthusiasts often tout the relaxing nature of a Jacuzzi. Here's why: A Jacuzzi's hot, pulsating water stimulates blood flow, which in turn causes the blood vessels to dilate and blood pressure to fall. A Jacuzzi's buoyancy quotient also helps to suspend the majority of a person's body weight -- triggering a calming feeling of floating ever so slightly in the water. The buoyancy factor, combined with the hotness of the water, improve circulation and provide relief to muscles and joints racked by stiffness or pain.
Numerous studies -- including one published in the British Journal of Rheumatology -- have underscored the value of spa therapy for people who suffer from neck, shoulder and back pain. In some cases, study participants have reported greater flexibility, a reduction in pain and less dependence on medications after regular sessions in a Jacuzzi.
