Leakage of water into the breathing loop of a rebreather, which dissolves alkaline material used to chemically remove carbon dioxide from exhaled air. This contaminated water may move further along the breathing loop and reach the diver's mouth, where it may cause choking, and in the case of strong alkalis, caustic corrosion of the mucous ...
The diver controls the flow rate of the water from a valve at the hip, allowing control of the warmth of the suit in response to changes in environmental conditions and workload. Tubes inside the suit distribute the water to the limbs, chest, and back. Boots, gloves, and hood are also supplied with hot water from the ends of the distribution hoses.
Naturally occurring water is often unfit to drink (see Potability of backcountry water). [11] Sweating removes not only water, but also salt. This may result in a deficiency of sodium (hyponatremia). Eating salty snacks together with drinking water helps to avoid this problem. [11] If deprived of food for several days, travelers may become ...

As it turns out, much like iced tea, plain old ice water hides all sorts of hidden dangers for your health.
Immersion in water and exposure to cold water and high pressure have physiological effects on the diver which limit the depths and duration possible in ambient pressure diving. Breath-hold endurance is a severe limitation, and breathing at high ambient pressure adds further complications, both directly and indirectly.
