Free diving is a form of underwater diving that relies on holding one's breath rather than using breathing apparatus like scuba tanks. Divers descend into the water to explore marine environments, often reaching depths of 20 meters or more. This activity requires training to improve breath-holding capacity and to ensure safety while diving. Free diving can be practiced for various purposes, including recreation, photography, and competitive sports. It is often associated with apnea competitions, where divers aim to reach the greatest depth or stay underwater the longest without breathing. Safety measures, such as diving with a buddy, are essential to prevent accidents.
