Freediving

Diving on a single breath without scuba gear, from casual reef breath-holds to competitive depth disciplines beyond 100 m.

Freediving is diving on a single breath, with no tank or regulator, relying on breath-hold, relaxation, and the body's own mammalian dive response, which slows the heart and shifts blood to the core as depth increases. It spans everything from snorkelers duck-diving a few meters over a reef to competitive athletes descending beyond 100 m in disciplines like constant weight, and record depths set at sites such as Dean's Blue Hole in the Bahamas.

Training focuses on breathing technique, equalization methods like the Frenzel maneuver that work with compressed lungs, streamlined finning with long blades or a monofin, and above all safety: the absolute rule is never freedive alone, because shallow-water blackout from hypoxia typically strikes in the last meters of ascent, exactly where a trained buddy can rescue you. One up, one down is the standard protocol.

For scuba divers, a freediving course sharpens equalization, calm, and water confidence, and there is one hard crossover rule: freediving immediately after scuba can provoke decompression sickness, so keep serious breath-hold sessions out of the hours following a scuba dive. Agencies like AIDA, Molchanovs, and PADI Freediver structure the training path. Many divers find the quiet of a breath-hold descent addictive in its own right.
