Exposure to cold water during a dive, and cold environment before or after a dive, wind chill. [46] Hypothermia: Reduced core temperature, shivering, loss of strength, reduced level of consciousness, loss of consciousness, and eventually death. Loss of body heat to the water or other surroundings. Water carries heat away far more effectively ...
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.

That is to say that, with the lungs fully inflated (or say at total lung capacity), they have slightly less specific gravity than water and will not start to sink until they exhale.

The tops of waterfalls are especially dangerous because of fast moving water and smooth, slanted rocks. Rubber soles grip poorly on slime, compared to felt soles, crampons, or hob-nailed boots. Precautions include being aware of the danger, using hiking poles, loosening packs straps to lower gravity and in case of becoming submerged, and ...
Freediving blackout, breath-hold blackout, [1] or apnea blackout is a class of hypoxic blackout, a loss of consciousness caused by cerebral hypoxia towards the end of a breath-hold (freedive or dynamic apnea) dive, when the swimmer does not necessarily experience an urgent need to breathe and has no other obvious medical condition that might have caused it.
