Hot Tubs Surpass Saunas in Health Benefits

A study from the Bowerman Sports Science Center at the University of Oregon, published in the American Journal of Physiology, finds that hot tub soaking may yield greater health benefits than traditional or far-infrared saunas. Researchers tested 20 healthy, active young adults and tracked physiological markers such as body temperature, blood pressure, heart rate, cardiac output, and immune response. Hot water immersion most effectively raised core body temperature, resulting in improved blood pressure regulation, enhanced immune function, and a stronger overall response to heat stress. These beneficial effects extended beyond the heat exposure itself. Experts note that hot tub bathing could be a more accessible and beneficial wellness practice than sauna use for many people. The findings directly challenge the widespread belief that saunas offer the best relaxation and health advantages.
