Studies & Articles

We are now living in a time when science can explain why humans have naturally turned to heat therapy to help treat a variety of physical, mental, and emotional disturbances. While the models of heat therapy have varied throughout cultures and history (sweat lodges, traditional Finnish saunas, Turkish Hammans), and technology has improved (infrared saunas), the essential mechanistic response within the body has remained the same. 

There is an ever increasing volume of research on how saunas can benefit human physiology. This is both exciting and, at times, overwhelming for the average person. It is no small undertaking to sift through the multitude of published journals filled with scientific and often laboratory-specific vernacular. The National Library of Medicine alone has over 12,000 published peer reviewed journals on the topic of how sauna use affects human physiology. 

Educating people on the use of sauna therapy is a primary aim of Through our numerous articles we endeavor to help enhance the understanding of the effects of sauna on health. In an ongoing effort to make sauna-related information more accessible and digestible, we have created this page to be a guide to help point you toward some of the most pertinent research involving various health conditions that respond well to saunas, infrared light, or temperature therapy in general (cold plunges, contrast therapy, and saunas).

Research & Data Collection For the Individual

We hope these articles and links provide you with the necessary tools to perform your own research on how saunas affect human physiology. Furthermore, has well over 150 articles that specify how sauna use may positively affect certain afflictions, as well as how to optimize your use of saunas.

The data is in, and as you can see there is no question that saunas in their many forms have a resoundingly positive effect on human health under most circumstances. As always, if you have questions or concerns about using a sauna, please consult with a medical practitioner, your family doctor, or specialist. 

Happy Saunaing!
