underwater swimming

Swimming is the act of swimming in water or other liquids, driven by the instinct for survival, recreation, sport, or other reasons. It is achieved through coordinated movement of the limbs, the body, or both. Humans are able to hold their breath underwater, and swimming is an innate ability within weeks of birth, as it is a response to human evolution.

Swimming is among the recreational activities enjoyed by a large number of people. In some countries, swimming lessons are a mandatory part of the school curriculum. As a fundamental sport, swimming has a range of local, national, and international competitions, including the Olympic Games.
