There is little scientific evidence to suggest that drinking cold water is bad for people. In fact, drinking colder water may improve exercise performance and be better for rehydration when exercising, especially in hotter environments.The body works harder to maintain its core temperature in cold water, leading to an increase in metabolic rate. This can be beneficial for those looking to burn calories and maintain a healthy weight.According to Harper, a cold swim increases your basal metabolic rate, meaning you burn off more calories afterwards.

These conditions can adversely affect the body’s ability to function properly, thereby increasing the risk of drowning.In summary, cold water swimming is great for our mental health. It releases endorphins and controls stress hormones. This improves our mood and brain function. It’s a natural way to reduce stress and improve our mental well-being.The cold water also encourages blood to flow, which can improve circulation over time, and is a positive long-term effect of cold water swimming.Cold water swimming has been found to increase the release of several mood-boosting hormones, including dopamine and serotonin.Our findings showed that participants felt more active, alert, attentive, proud, and inspired and less distressed and nervous after having a cold-water bath.

Swimming in cold water activates the brown fat cells and help to manage the body weight. Cold water strains your body — it goes into “survival mode,” working hard to maintain its core temperature. This stimulates your body to increase blood flow circulation. Increasing circulation redistributes blood and delivers freshly oxygenated blood to areas of the body that need to recover,” Dr. Hame says.Swimming in cold water can increase your metabolic rate by forcing your body to burn more calories to keep warm.

Contracting of blood vessels for too long can deprive the skin of essential nutrients and oxygen .The shock of cold water against the skin triggers a fight-or-flight response.

Does swimming in cold water build muscle?
For athletes, cold-water immersion may affect different types of training in different ways. For those engaged in resistance training, cold water may turn down the molecular signaling pathways that are normally activated after exercise. This may hinder long-term improvements in strength, muscle growth and performance. Reduces muscle soreness and stiffness – Cold water swimming therapy has been shown to help with muscle and joint pain as it helps to reduce swelling and inflammation. Not only can this ease the pain associated with arthritis but it also helps with muscle soreness after physical activity.Cold Therapy May Increase Testosterone Levels Research has shown that when you use cold water therapy, testosterone levels may rise. In a study published in the Journal of Strength and Conditioning Research, researchers had professional soccer players complete sprint exercises and then enter a cryotherapy chamber.What are the benefits of cold-water therapy?
