Soaking in a Hot Tub Bestows Surprising Health Benefits, Even More Than Saunas, New Study Says

Key Points:
- Researchers from the University of Oregon compared the effects of saunas, dry heat, and hot water immersion on exercise recovery and longevity, finding that hot water immersion most effectively raises core body temperature and triggers beneficial vascular responses.
- The study, involving 20 young, healthy adults, showed that only hot water immersion produced a measurable inflammatory response through increased levels of inflammatory cytokines and immune cell activity.
- Hot water immersion limits the body's ability to dissipate heat via sweating, leading to more robust increases in core temperature compared to air-based heat therapies like saunas.
- Heat therapies, including saunas and hot tubs, can mimic some cardiovascular benefits of exercise by raising heart rate, making them potentially useful substitutes for aerobic exercise when physical activity is limited.
- Experts emphasize that heat therapy should be done in moderation and with medical consultation, as longer and more frequent sauna sessions have been linked to improved longevity and heart health in previous research.
