Water, like any other substance, can be considered a poison when over-consumed in a brief period. Water intoxication mostly occurs when water is being consumed in a high quantity provoking disturbances in electrolyte balance. [2] Excess of body water may also be a result of a medical condition or improper treatment; see "hyponatremia" for some ...
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.
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.
As it turns out, much like iced tea, plain old ice water hides all sorts of hidden dangers for your health.
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 ...
Groups who decide to remain uncontacted are referred to as indigenous peoples in voluntary isolation. [1] Legal protections make estimating the total number of uncontacted peoples challenging, but estimates from the Inter-American Commission on Human Rights in the UN and the nonprofit group Survival International point to between 100 and 200 ...
