Diving Physiology
Diving physiology involves how the body responds to the underwater environment. As a diver descends, pressure increases, affecting the lungs and other air-filled spaces, which can compress or expand. Breathing compressed air can lead to nitrogen absorption in the bloodstream; if ascent is too rapid, this can cause decompression sickness, or “the bends.” The body also adjusts to cooler temperatures and increased physical exertion. Proper training and techniques help manage these effects, ensuring divers can explore underwater safely while minimizing risks to their health.

Diving physiology focuses on how the body reacts to changes in pressure and oxygen levels underwater. As a diver descends, pressure increases, affecting gas absorption in the lungs and bloodstream. This can lead to conditions like nitrogen narcosis or decompression sickness (“the bends”) if divers ascend too quickly. Breath-holding also limits oxygen intake, making it crucial for divers to manage their air supply. Understanding these physiological responses helps ensure safety, enabling divers to enjoy underwater exploration while minimizing health risks associated with pressure changes and gas exchange.
