Hot Tubs May Offer Greater Health Benefits Than Saunas

Recent research indicates that soaking in a hot tub might provide more significant health advantages compared to traditional saunas. A study conducted by researchers at the Bowerman Sports Science Center, University of Oregon, analyzed how different passive heat therapies affect the body. Participants immersed in hot water, sat in dry heat saunas, and used infrared saunas while their physiological responses were measured.

The findings revealed that hot water immersion most effectively elevated core body temperature, which is linked to various health benefits such as improved vascular function and immune response. The increase in core temperature during hot tub soaking enhances blood flow, which can be beneficial for cardiovascular health and stress reduction. Interestingly, hot water immersion also triggered a notable inflammatory response, including increased levels of cytokines and immune cells, largely because the body struggles to dissipate heat efficiently in water compared to air.

The study involved 20 healthy young adults, both men and women, aged 20 to 28. They followed a controlled schedule of heat exposure, and researchers assessed parameters like blood pressure, heart rate, cardiac output, and immune markers before, during, and after each session.

Lead researcher Jessica Atencio highlighted that the physical response to hot water immersion is particularly robust, which could make it a valuable health intervention. While regular exercise remains the most effective non-pharmacological approach to health, heat therapy like hot tub sessions offers a peaceful, social, and culturally rich alternative, especially for those who cannot exercise.

Experts emphasize the importance of moderation and medical clearance before beginning any heat therapy routine. As heat exposure can offer health benefits such as lowered blood pressure, enhanced immune function, and improved heat stress response, it should be integrated thoughtfully into one’s health regimen.

Overall, this research suggests that incorporating hot water immersion into one’s lifestyle could be a safe and effective way to promote health, complementing physical activity or serving as an alternative for some individuals. Always consult healthcare professionals before starting new therapies.
