In the Arctic, you can hardly easily find fuel and food, but you can be sure that you will not suffer from thirst. When water in the Arctic conditions in the form of snow or ice around is abundant, dehydration does not threaten you. In addition, these sources of water in arctic conditions are usually clean..
Collection and purification of drinking water in arctic conditions, melting of snow and ice to produce drinking water.
However, the use of snow or ice increases the risk of hypothermia. This is a major problem in arctic conditions. When you swallow cold, the temperature of the throat, neck, and therefore the whole body goes down. A large supply of warm blood is continuously pumped through the arteries of the neck. It enters directly into the brain, and then through the jugular vein then enters the heart again. Therefore, it is especially important not to supercool the neck.
Cleaning and melting snow and ice to produce water in arctic conditions.
Although the safest option for treating water in arctic conditions is boiling, fresh snow and ice, collected in places where there is no stagnant water or other visible sources of pollution, can be consumed without much concern. Most bacteria living in abstraction do not survive freezing temperatures.
If you have a choice, give preference to ice, not snow. Ice has a higher density of the liquid it contains. While snow is partially composed of air. Melt the ice with the heat of your body or on fire. In arctic conditions, fuel is a precious resource. Therefore, if possible, use your body heat to get drinking water in the Arctic from ice.
If absolutely necessary, melt ice with the heat of your body, not on fire.
At the same time, when there is no shortage of fuel, melt ice on a fire.
When choosing between water and ice, always give preference to water rather than ice.
When choosing between snow and ice, always give preference to ice rather than snow.
If you are dressed appropriately, that is, in several layers, then during the movement, no matter how cold it is around, your body will generate a huge amount of heat. To melt the ice, do not apply it to the passages of the brachial arteries that go through the armpits and the femoral arteries on the inner thighs. Since these are the most important parts of the body’s blood supply system.
Place snow or ice in a bottle or other suitable water tank. And to melt them, put this bottle or container between the layers of your clothes. During long stops, take care of the heat of your body and continue to melt snow or ice on fire.
