Sweating has been linked to healthy things such as releasing toxins, burning fat and many more. But with sauna, can sweating help in improving one’s immune system? In studies from Austria and Finland, it was discovered that regular sauna use has improved the respondent’s immunity to respiratory diseases and colds. Now, how does sauna exactly do this?

According to Cisoń et al. (2013), a single sauna session has resulted in increased levels of white blood cells, lymphocytes, neutrophils, and basophils in participants. It was the idea of having heat stress that lead to mobilization of immune cells into the blood stream which enhanced the readiness against pathogens. Basically, another byproduct of increased blood flow due to vasodilation and contrast therapy. Another impact of sauna sessions is the mild “fever effect” that sauna gives the body. As we all know, fever is a response of the body to infection, increasing the body temperature as a response to infection. With a sauna induced “fever effect”, it leads to a release of heat shock proteins (HSPs) which help in cellular repair and stress resilience.

Over time, consistent sauna use helps the body adapt to controlled heat stress, that leads to immune responses being more efficient, and balanced. One session may temporarily boost circulation and immune activity, regular sauna sessions help in building that resilience and protection. Disclaimer, sauna is not a cure or an immunity shield. It is simply an aid that helps us protect our bodies. Together with good diet, sleep, and a healthy lifestyle it will for sure help you in achieving these goals.
