Hot tubs and heart disease: Trouble or treatment?

Interestingly, the observation that blood pressure can be lowered by hot tub immersion, and an old observation that excess water can be effectively driven from the body by the diuretic effect of what was called many years ago “head out water immersion,” has led to the thought that this could be used as a treatment of patients with congestive heart failure. Recent scientific studies on the use of hot tubs in patients with congestive heart failure have demonstrated clinical benefits. No studies or observations have suggested danger to pacemaker patients in the use of hot tubs.

It is important to note that all hot tub studies in “cardiac patients” have been limited to 10-minute exposures (at 106 degrees Fahrenheit) and have been done in safe conditions. Neither scalding water nor blistering heat is beneficial for anyone. Slippery surfaces still cause more accidents then cardiac or infectious problems in the sauna, whirlpool, Jacuzzi or hot tub. As always, please consult your physician.
