Immersing your body in cold water stimulates the release of an invigorating cocktail of chemicals.

“It's like pressing Control-Alt-Del on your computer,” says Cath Pendleton. “When I'm in the water, I get so focused on my body that my brain switches off. It's just swimming with me.”
Pendleton, an ice swimmer based in Merthyr Tydfil, England, is as tough as anyone. In 2020, five years after she realized she didn't mind swimming in very cold water, she became the first person to swim one mile inside the Antarctic Circle. Part of her training included sitting in a freezer in a shed.
But she's not the only one passionate about cold water. Rivers, lakes, and oceans that were once home to a handful of serious year-round swimmers are now on the verge of extinction, thanks to media reports about the mental health impact of frigid dips and pool closures due to COVID-19. The number of people visiting is rapidly increasing. An estimated 7.5 million people swim outdoors in the UK alone, and more and more people swim outdoors during the winter. Global numbers are hard to come by, but the International Winter Swimming Association is seeing a boom in winter swimmer registrations around the world, including in China, Russia and Finland, where water temperatures can drop below 0C.
But what could be better than the joy of being in nature and the perverted feeling of happiness that defies the cold? According to the latest research, the answer is probably: Recent studies are beginning to uncover evidence that cold water immersion can reduce stress and depression, and may help deal with autoimmune diseases.
