Large or sudden changes in ambient pressure have the potential for injury known as barotrauma. Breath-hold duration is limited by oxygen reserves, the response to raised carbon dioxide levels, and the risk of hypoxic blackout, which has a high associated risk of drowning. Exposure to cold water can result in the harmful cold shock response, the helpful diving reflex and excessive loss of body heat. Immersion affects fluid balance, circulation and work of breathing. All of these may affect diver performance and safety. Several factors influence the diver, including immersion, exposure to the water, the limitations of breath-hold endurance, variations in ambient pressure, the effects of breathing gases at raised ambient pressure, effects caused by the use of breathing apparatus, and sensory impairment. It, therefore, includes the range of physiological effects generally limited to human ambient pressure divers either freediving or using underwater breathing apparatus. Human physiology of underwater diving is the physiological influences of the underwater environment on the human diver, and adaptations to operating underwater, both during breath-hold dives and while breathing at ambient pressure from a suitable breathing gas supply. ![]() For Physiologiacl influences of the underwater environment on air-breathing vertebrates, see Physiology of underwater diving.
