More people are trying cold-water swimming and ice baths to improve their health and mood naturally. Many enthusiasts report feeling mental and physical benefits, but experts caution that these activities pose real risks if not done safely, according to the Associated Press.
Dr. Mark Harper, an anesthesiologist who researches cold-water immersion, explains that brief periods in cold water may help improve mental health by triggering a brief stress response in the body. This process, known as hormesis, can release endorphins and reduce inflammation. Many swimmers also report feeling more confident and happier after regular cold dips.
«There’s a strong base suggesting positive effects on mental health,» Harper said, «but not yet hard evidence.»
Scientists emphasize that cold-water immersion can be dangerous. Dr. Mike Tipton, a physiologist at the University of Portsmouth, warns that jumping into icy water can prompt gasping, rapid breathing and even drowning. Staying in too long may harm nerves and blood vessels, similar to frostbite.
«You don’t need to go to extremes,» Tipton said. «Temperatures between 15 and 20 degrees Celsius for a couple of minutes are enough.»
Experts suggest entering the water slowly, swimming in areas with supervision and consulting a doctor first if you have heart or breathing problems.
Earlier this week, Pavel Durov, the founder of Telegram and a longtime advocate of fitness and a healthy lifestyle, visited Lake Kolsay near Almaty, where he swam in icy water, surprising fans with his impressive physique.
