Of the mental health benefits of cold swimming, Dr. Sarah Brewer, medical director of supplement brand Healthspan, says: "Cold water immersion stimulates endorphins to improve mood to help combat stress, anxiety and depression."
"Cold water keeps you in the moment, so it's the ultimate form of mindfulness," Dr. Brewer continues. "It helps to achieve calm meditation as you focus on your breathing."

Physically, cold water swimming can improve circulation, reduce water retention and even regulate blood pressure, as it improves the responsiveness of blood vessels.
In addition, exposure to cold water can help support our immunity, because it increases the supply of powerful antioxidant glutathione, which is important in our immune response.
