Saunas and hot tubs have long been preferred for relaxation and muscle relief. However, recent scientific studies reveal that hot tubs—particularly when evaluated as a form of hot water therapy—may offer far more comprehensive health benefits than previously assumed. A study conducted at the Bowerman Sports Science Center at the University of Oregon compared traditional saunas, infrared saunas, and hot water therapy, providing valuable insights into the physiological effects of heat-based applications.

The study involved 20 physically active participants between the ages of 20 and 28. Participants were exposed to three different heat therapy methods: a 45-minute session in a hot tub at 40.5°C, three 10-minute sessions in a traditional sauna at 80°C, and a 45-minute session in an infrared sauna at temperatures ranging from 45°C to 65°C. Body temperature, heart rate, blood pressure, immune cell levels, and inflammatory biomarkers were measured before, during, and after each session.

The study’s lead author, doctoral student Jessica Atencio, emphasized that direct immersion in hot water allows heat to penetrate the body more efficiently, resulting in deeper warming. This process has been shown to increase blood flow, support vascular health, and activate the immune system. While traditional saunas primarily heat the body through sweating and produce a more superficial effect, infrared saunas focus on muscle relaxation at lower temperatures.

Professor Christopher Minson, who led the research, stated that when applied regularly, heat therapy can promote long-term improvements in cardiovascular health, lower blood pressure, and enhance the body’s ability to cope with stress. He also noted that for individuals unable to engage in regular exercise, hot water therapy can serve as an effective alternative.

In conclusion, the study demonstrates that hot tubs are not only tools for relaxation but also provide significant support for cardiovascular health, immune function, and overall well-being. Scientific evidence suggests that by delivering deeper heat penetration, hot tubs may offer more comprehensive physiological benefits compared to saunas.
