Are there health benefits of going to the sauna?

Sauna use offers several notable health benefits, particularly related to cardiovascular health and longevity. Regular sauna sessions—ranging from two to three times per week—can reduce the risk of cardiovascular events by 27%. More frequent use, such as four to seven times weekly, may reduce this risk by up to 50% [1].

From a physiological perspective, sauna exposure mimics cardiovascular exercise by increasing heart rate, blood flow, and vasodilation. This heart workout is achieved without the physical impact on joints and muscles experienced in typical exercise [2]. Moreover, sauna use also impacts hormonal levels, such as boosting growth hormone and reducing cortisol, which can contribute to overall health improvement [2].

Saunas have cognitive benefits as well. They enhance cognition through increased blood flow to the brain, similar to the effects of moderate exercise. Regular sauna use has been associated with a significantly reduced risk of dementia and Alzheimer's disease [3].

Additionally, sauna exposure can boost immune function. It increases leukocyte levels, which are crucial for a robust innate immune response. This effect is particularly beneficial when done regularly and at safe heat levels [4].

In essence, regular sauna use can effectively promote cardiovascular health, improve hormonal balance, support cognitive function, and strengthen the immune system.
