According to (Gryka et al., 2021), repeated sauna and cold plunge sessions significantly dropped cortisol levels. They are more commonly referred to as “stress hormones.” They are the hormones that your body pumps out when you’re stressed. While it is also responsible in helping you react quickly in tough situations, high levels of these hormones can cause chaos. These usually lead to poor sleep, mood swings, anxiety, digestive issues, and even long-term health concerns such as cardiovascular problems.
However, with the help of regular sauna use these hormones seem to be lowered. With alternation of intense sauna heat and the sharp coldness of a plunge, the body is trained to regulate itself more efficiently. Aside from the physiological response of lowered cortisol levels, it also sports a calmer nervous system that help people feel balanced and recovered. To put it simply, lowered stress levels = more relaxation, better sleep, better body.
