When the human body performs outdoor sports, chest dehydration is very likely to occur at high altitudes, because perspiration (nacl 0.2% in sweat), breathing, urination, and diarrhea can all lead to the loss of water in the body. In the cold mountainous regions, because the air is extremely dry, the body surface evaporates quickly, and at the same time it discharges a large amount of water through rapid breathing movements, but often it is not consciously perceived, resulting in symptoms of dehydration (hypertonic dehydration). For diseases caused by high temperatures, colds, and acute mountain diseases, maintaining good fluid uptake is an important prevention and control measure. Not only can the chance of getting sick be reduced, but also the overall physiological function of the climber can be greatly enhanced.
