Hot Tub Therapy Results in Lasting Reduced Hypertension
Recent NASMI studies show that warm water immersion like that offered by hot tub therapy significantly decreases both systolic and diastolic blood pressure. In these studies a reduction in blood pressure also occurred during immersion in cold and neutral temperatures to a degree. However, diastolic blood pressure was reduced significantly more in warm water. Even though blood pressure seemed to be lowered with immersion in all water temperatures, the positive effects of lowered blood pressure remained with the individual much longer after leaving warm water than after exiting water with cold and neutral temperatures. This was especially evident in the study participant’s diastolic blood pressure.
