Cold bath

When spring arrives, many winter swimmers begin to long for the coming winter so they can swim in cold water again. Cold bathing or ice bathing has become a hot trend and social media is filled with pictures and stories of successful cold baths. Superlatives about the positive effects of cold bathing abound, and many experience increased well-being, both physically and mentally. Exposing oneself to cold bathing often means overcoming a barrier and stepping outside one's comfort zone. Once people start ice bathing, it becomes a good habit for many, almost like an addiction they can't do without, and they continue bathing all year round.

What does cold bathing do?

Cold bathing, or swimming in cold water, can trigger several physiological reactions in the body. When you immerse your body in cold water, you first experience a "cold shock," which can lead to hyperventilation and an increased breathing rate. Adrenaline surges through the body, resulting in increased blood pressure and the release of glucose and fat into the blood to provide energy in the event of a "fight-or-flight" response. At the same time, cortisol, a stress hormone, is released, and endorphins provide a feeling of euphoria. Many people find cold bathing good for post-exercise recovery and that it can reduce stress and everyday worries, as well as improve sleep. In addition, cold bathing can promote brown fat, which has the task of generating heat by burning fatty acids and glucose.
