A good soak in a hot tub might beat a sauna for health benefits

Hot tubs and saunas are popular choices for relaxation and providing warmth, but recent research suggests that hot tubs might offer more health benefits than saunas. A study conducted by researchers at the Bowerman Sports Science Center at the University of Oregon compared the physiological effects of soaking in a hot tub to sitting in traditional dry heat saunas or far-infrared saunas.

The study, led by doctoral student Jessica Atencio under the guidance of Christopher Minson, compared the impact of each heat therapy on core body temperature, blood pressure, heart rate, cardiac output, and immune responses. The research involved 10 men and 10 women aged 20 to 28 years who regularly exercised to isolate the physiological responses to each heating method in a young, healthy population.

The results, published in the American Journal of Physiology, showed that soaking in hot water had the most significant impact on increasing core body temperature. This increase in body temperature led to improved blood flow, which is beneficial for vascular health. Additionally, hot water immersion was the only heat therapy that produced an inflammatory response, as measured by levels of inflammatory cytokines and immune cell populations in the blood.

Minson, who has studied heat therapies for over two decades, emphasized the potential health benefits of heat therapy when done in moderation. While regular exercise can provide similar benefits, heat therapy can be a suitable option for individuals who are unable or unwilling to exercise. Combining heat therapy with exercise can offer a holistic approach to promoting health and well-being.

Atencio highlighted the importance of safety and moderation when engaging in heat therapy, especially for individuals who may have underlying health conditions. Consulting with a physician before starting a heat therapy regimen is essential to ensure it is safe and beneficial for the individual.

Overall, the study suggests that hot tubs might offer unique health benefits compared to saunas, particularly in terms of increasing core body temperature and stimulating immune responses. Incorporating heat therapy into a wellness routine, alongside exercise and proper medical guidance, can contribute to improved health and well-being.
