Taking a hot sauna regularly can feel good and relax you, but can it also prevent heart disease and Alzheimer’s disease?
If you’re from the US, you probably associate saunas with gyms and spas. But saunas have existed in some form for hundreds of years, particularly in Scandinavia, where they are used regularly as part of the culture. Nowhere are they more ubiquitous than in Finland – it is estimated that 99% of Finns use one at least once per week. They have traditionally been used as places to relax with friends and family and to recover from intense physical activity.
And while sauna usage is typically associated with health behaviors, like for example using a sauna after exercise or before sleep as a way to relax, research has now taken a closer look to see if sauna usage itself is health promoting.
In the newest episode of humanOS Radio, I talk with Jari Laukkanen, MD, Ph.D. Jari is a clinical cardiologist who runs a research lab at the University of Eastern Finland. He primarily studies the role of a wide range of cardiometabolic risk factors in relation to cardiovascular disease. In his latest study, he and his colleagues examined thousands of Finnish men over the course of two decades. Participants were divided into groups based on how frequently they sauna. It turns out that men who sauna more frequently appear to have a tremendous benefit to their heart and brain health. Listen here to learn more.
