The instant shock of the cold causes involuntary inhalation, which, if underwater, can result in sinking. The chilly water can additionally create cardiovascular disease due to vasoconstriction; the heart needs to function more difficult to pump the same volume of blood throughout the body. For people with existing cardiovascular disease, the added workload can result in heart attack. Breathing of water might arise from hyperventilation.
Conditioning versus the cool shock response is a reliable and also expense effective way to prevent drowning. Those that profit the most from the habituation of a cool shock reaction are professional athletes, soldiers and those that go to risk of cool water immersion. Even though it might be t-shirt weather as well as the air is warm, the water can still be extremely cool.
