Ice swimming is a winter sport that involves swimming in freezing water, typically in lakes or rivers that are partially frozen. Participants often cut a hole in the ice to create a swimming area. Swimmers usually wear minimal clothing, such as swimsuits, to enhance the challenge and experience. This activity is popular in countries like Finland, Russia, and Sweden, where it is often associated with winter festivals and health benefits. Ice swimming is believed to improve circulation, boost the immune system, and provide a sense of exhilaration. Safety measures, such as having a lifeguard present, are essential during these events.
