A new study gives greater scientific insight into how icy-water swimming, cold showers, ice baths and exposure to cooler water and air temperatures might drive health benefits.
starts his day by hitting the beach at Coney Island for a dip in the frigid Atlantic Ocean -- no matter how low the mercury plummets.
Taking a dip in icy-cold water cuts “bad” body fat in men, according to the analysis published in the peer-reviewed International Journal of Circumpolar Health. It also boosts the development of “good” fat that helps burn calories and combats obesity, cardiovascular disease and diabetes, the authors concluded.from UiT who led the new research, says that many small studies over the years have hinted at the benefits of cold-water immersion.
“Ice swimming,” where the frozen ice over a lake or pond has been removed to expose the water below, is so common that global organizations have sprung up around the practice: the International Ice Swimming Association and the International Winter Swimming Association. For the review, Mercer’s team conducted a detailed search of scientific literature on the issue, excluding studies where participants wore wet suits, experienced accidental cold-water immersion and water temperatures greater than 68 degrees.Some studies showed solid evidence that cold-water swimmers often experience significant improvements in overall cardiovascular health.
Exposure to cold water or air boosts BAT’s production of adiponectin, a protein that helps protect against insulin resistance, diabetes and other diseases. They added that other factors – beyond simply cold-water exposure – may play a role in the health benefits the studies observed. For instance, cold-water swimmers may be “naturally healthier” as a group and tend to live active lifestyles. They experience positive social interactions from such activities, have learned how to handle stress , eat healthy foods and demonstrate “a positive mindset,” the authors report.
Wearing cold, wet socks also help improve blood and nutrient circulation by stimulating a pump-like effect within the circulatory and lymphatic systems, increasing vitality and speeding recovery from an acute illness with fever. Even so, Mercer says he would not hesitate to recommend cold-water swimming, based on his own research.
