The Mayo Clinic reported that relaxing in a hot tub can be good for patients with heart problems. Their study showed that soaking in a hot tub may have benefits over working out because hot tubs lower blood pressure while exercise raises blood pressure. Thus, soaking in a hot tub applies less stress to the heart. While this study and report published helpful and promising information, it is still recommended that you consult your doctor before using a hot tub if you have any heart condition.

Lowered blood pressure is achieved through the hot tub’s heat and buoyancy. The water’s heat dilates constricted blood vessels and increases blood circulation. The water’s buoyancy decreases the effects of gravity on the body. These two factors decrease the amount of force the heart must exert with each beat. Another benefit of hot tubs is that increased blood flow and pressure helps to promote white blood cells and antibodies—boasting the immune system and aiding in healing.

Other conditions that may benefit from the increased circulation benefits of submersed-bathing hydrotherapy are deep vein thrombosis (DVT) and varicose veins.
