Open water swimming refers to swimming in natural bodies of water, such as oceans, lakes, and rivers, rather than in a controlled environment like a swimming pool. This type of swimming can vary in distance and conditions, often involving longer distances and unpredictable elements like waves, currents, and varying water temperatures. Participants in open water swimming may engage in recreational activities, competitive events, or training for triathlons. Safety is crucial, as swimmers should be aware of their surroundings and potential hazards, such as marine life or changing weather conditions. Proper gear, like wetsuits and buoyancy aids, can enhance safety and comfort.
