Hot Tub benefits May⁣ outweigh sauna, Study⁢ Finds

⁣ Updated June 26, 2025

For relaxation ⁢and muscle relief, both hot tubs and saunas are popular ⁤choices. However, new research from the University of Oregon suggests that ⁣the benefits of hot tub use may extend further than those of traditional saunas.

The study, conducted ‍at the Bowerman ⁣Sports Science Center, examined the effects of ‍ hot water immersion compared to dry heat and far-infrared saunas. Researchers found that soaking in a hot ⁢tub can raise core body temperature,leading ⁣to lower blood pressure and a stimulated immune system. These positive effects can also last beyond the soak‍ itself.

Jessica Atencio, lead author and doctoral student, noted that the study compared common methods of passive⁢ heating. The findings, published in ⁤the American Journal of Physiology, detail how researchers monitored participants’ body temperature, blood pressure, heart rate, and immune responses before, ‍during, and after each heat therapy.

The study involved 10 men and⁤ 10 women, ages 20-28, all of whom exercised regularly. ‍The aim was to isolate the physiological responses to each heating method in a healthy, young group.

According⁢ to Atencio, hot⁣ water immersion proved most effective in raising core body temperature, ⁢which ‍drives increased blood flow and benefits vascular health.⁤ Blood⁤ samples revealed that only hot water immersion triggered an inflammatory response, indicated by levels of immune signaling molecules.

Christopher Minson, professor of human physiology and director of the Bowerman Center, has studied heat therapies for ⁤over 20 years.He believes that moderate heat therapy‍ can improve health.⁤ Minson also pointed out that while regular exercise offers similar or even greater benefits,heat therapy presents a viable⁣ option for those unable or unwilling to exercise.

⁤ “There’s there’s no doubt whatsoever in my mind that if people are willing to do some heat therapy, it’s going to align with improved health, provided that‍ it’s done in moderation,” Minson said.

Minson also emphasized the potential social and cultural aspects of heat therapy, contributing to its overall health benefits. ⁤He advises individuals to consult with their⁢ doctors before starting any⁢ heat therapy or exercise program.

Atencio, a runner herself, sees heat therapy as a valuable supplement. “We always say that exercise is the primary nonpharmacological treatment that people should be‍ doing to promote health,but some people can’t or just‍ won’t exercise,” she said. “Heat therapy is good supplementation.”
