Freefall diving, also known as free diving, is a form of underwater diving that relies on holding one's breath rather than using breathing apparatus. Divers descend into the water without tanks, exploring the underwater environment while relying on their ability to manage their breath and equalize pressure in their ears. This activity can be practiced for recreation, sport, or even competitive purposes. Freefall diving requires training to ensure safety and efficiency, as divers must learn techniques for relaxation, equalization, and safe ascent. Popular locations for free diving include coral reefs and underwater caves, where divers can experience marine life up close.
