New Delhi, Jun 26: For many, a session in the sauna is the ultimate go-to for relaxation, especially during the colder months. But for those who lack access to saunas or find them expensive, there’s good news brewing in the world of wellness. A new study now suggests that a far simpler, more accessible ritual may actually offer better health benefits than traditional or even far-infrared saunas.
According to research conducted by the Bowerman Sports Science Center at the University of Oregon, hot-water immersion—or more simply, soaking in a hot tub—has emerged as a more effective health booster compared to dry and infrared saunas. The findings, published in the American Journal of Physiology, have caught the attention of health experts worldwide.
In the words of lead researcher Jessica Atencio, a doctoral student working under the guidance of Prof. Christopher Minson, “We compared the most commonly utilized modalities of passive heating as they’re used in everyday life. No study until now has compared the acute responses between the three.”
The study observed 20 healthy, active young adults—equally divided between men and women—who underwent sessions in traditional dry saunas, far-infrared saunas, and hot-water baths. Their vital parameters such as heart rate, blood pressure, core body temperature, cardiac output, and immune system markers were closely monitored before, during, and after each session.
Remarkably, the hot tub session showed the most significant rise in core body temperature—a key trigger for the body’s positive physiological responses. This spike led to improved blood circulation, reduced blood pressure, and stronger vascular activity. Even more striking was the immune response: only the hot-water immersion caused a measurable increase in inflammatory cytokines and immune cells, suggesting a tangible boost to the immune system.
Atencio added, “Raising your core temperature in this way can enhance vascular health due to the increased blood flow. Over time, this helps the body respond better to heat stress and supports cardiovascular and immune resilience.”
In simple terms, for those who thought sauna sessions were the pinnacle of passive heat therapy, this research may well shift perspectives. Experts now agree that something as straightforward as a soak in hot water—not even requiring a fancy spa or gym membership—could hold the key to long-term health benefits.
So the next time you consider skipping your evening bath, think again—it could be your most potent tool for better blood pressure, immunity, and overall wellness.
