Which condition can develop if freediving too deeply without proper training?

Freediving to great depths without proper training can lead to a shallow water blackout, primarily due to the physiological changes that occur during the dive. When a freediver descends, they hold their breath for extended periods, which can lead to the depletion of oxygen levels in the body. If a diver ascends too quickly or remains underwater too long, they may lose consciousness, often occurring shortly after surfacing due to a lack of oxygen to the brain. This phenomenon is particularly dangerous, especially in shallow waters, as it can lead to drowning if the diver is not supervised or does not have sufficient buoyancy control.

Training is crucial because it teaches divers how to manage their breath-hold times, recognize the signs of hypoxia (insufficient oxygen), and properly execute safe ascents. Without adequate education and experience, the risk of shallow water blackout increases significantly, making it a critical concern for those participating in freediving activities.
