Breath-hold diving, also known as free diving, is a technique where divers hold their breath while exploring underwater without the use of breathing apparatus. This method allows divers to experience the underwater environment more intimately and can be practiced in various settings, from shallow waters to deeper ocean dives. Divers often use specific techniques to extend their breath-holding capacity, such as diaphragmatic breathing and relaxation methods. Safety is crucial in breath-hold diving, as it can lead to risks like shallow water blackout. Many divers train to improve their skills and ensure they dive safely, often participating in freediving competitions.
