Decades of research show that exposure to cold in various forms can be beneficial for the heart, immune system, and skin. This was reported by daily mail.
Scientists from the University of Birmingham say exercising in the cold can strengthen the heart and reduce the risk of acute respiratory viral infections. Additionally, this type of exercise requires a lot of calories as the body also needs to maintain its temperature. To do this, the body is forced to increase blood circulation, so the heart works harder. In addition, training in the cold helps the immune system better prepare to face viruses and reduces the risk of acute respiratory viral infections.
Research shows that exercise can be four times more effective than antidepressants. Exercising outside in the winter can facilitate the release of endorphins, which are especially helpful for seasonal affective disorder.
Finally, exercising outdoors helps increase blood levels of vitamin D, which is associated with better skin quality. Additionally, soaking or immersing in cold water constricts blood vessels, reduces pores and redness, reduces swelling and inflammation, relieving muscle pain and tension. However, evidence for the benefits of cold water therapy is inconclusive and based on small studies or human experience. Experts from the University of Portsmouth warn that diving requires caution as effective and safe diving parameters are not yet known.
