Freediving is a form of underwater diving that relies on holding one's breath rather than using breathing apparatus. Divers descend into the water to explore marine environments, often reaching impressive depths. This activity can be practiced for recreation, competition, or as a means of spearfishing. Freediving requires training to improve breath-holding capacity and underwater techniques. Safety is crucial, as divers must be aware of risks such as shallow water blackout. Many freedivers use techniques like static apnea and dynamic apnea to enhance their skills and performance in the water.
