What does proper buoyancy control during a dive help prevent?

Proper buoyancy control during a dive is crucial for several reasons, all contributing to a safer and more environmentally conscious diving experience.

Firstly, it helps prevent decompression sickness. When divers are not properly buoyant, they may ascend or descend too quickly, which can lead to nitrogen bubbles forming in the body as pressure changes rapidly. This condition, known as decompression sickness, can result in severe health complications.

Secondly, buoyancy control is vital in preventing overexpansion injuries, particularly in relation to air spaces in the body such as lungs. If a diver ascends too rapidly without proper buoyancy, the air in their lungs can expand excessively, potentially causing rupture or other injuries.

Lastly, good buoyancy control is essential in protecting delicate underwater ecosystems, particularly coral reefs. When divers lose control, they may unintentionally come into contact with corals or seabeds, causing damage to marine habitats. With effective buoyancy management, divers can navigate the underwater environment more gently and responsibly, minimizing their impact on marine life.

Therefore, effective buoyancy control serves to mitigate the risk of decompression sickness, prevent overexpansion injuries, and protect coral and other marine ecosystems, which collectively justifies the response that it helps prevent all of the mentioned issues.
