Despite record-breaking warm air temperatures in late May, water temperatures have remained dangerously low, creating a serious risk of cold water shock. Cold water shock occurs when the body reacts to sudden exposure to cold water, triggering hyperventilation, increased heart rate, and a surge in blood pressure.
