Everest, the Tibetan people, is called the “gift of lifeâ€, because the glacier-formed water that is draped in the peaks has become the river that nurtures the earth; but some people call him the “killer†because many climbers, including the world Famous mountaineers and generations of Sherpas living on the southern slopes of Mount Everest are buried in its embrace. Since the British expedition conquered the Everest for the first time in 1921, about 600 mountaineering warriors have embarked on the summit of the world's highest peak. During this period, 140 people also sacrificed their lives. The disaster that occurred in mid-May 1996 marked the worst scene in the history of human conquest. Within 36 hours, 8 people were killed, including the best mountaineers in the world. After painstakingly analyzing the causes of the tragedy, people have finally recognized several factors that threaten life in the mountains. They include:
Cold: This is the "top killer" causing deaths in high latitudes and alpine regions. In mid-May this year, it was supposed to be the golden season for climbing Mount Everest. However, the sudden arrival of Blizzard caused the temperature in the vicinity of the peak to drop to -40°C in a very short period of time, which caused great difficulties for the climbers. hurt. The extreme cold can cause people to lose a lot of heat, slow down the heart movement, and eventually lead to death.

For this reason, some developed countries have specially developed cold insulation clothing for the mountaineers in order to reduce the loss of body heat. The human body can generate heat during exercise and muscle shake, protecting the heart and body.
Oxygen loss: It was determined that the oxygen content in the atmosphere at the summit of the Mount Everest is only one third of the oxygen content in the sea level atmosphere. Oxygen deficiency can make people prone to fatigue. At low altitudes, people only need to breathe 12 times per minute. Near the peak, they must breathe 50 times to ensure the body's normal oxygen needs and ensure that the carbon dioxide in the lungs is discharged. Increase the body's oxygen content. At present, except for some special mountaineering projects, most climbing expeditions are equipped with lightweight, reliable oxygen cylinders to increase the safety of climbing.
Dry wind: Although the peaks are often covered by snow and ice, the wind there is very dry. Every time a climber loses his breath, he loses water. According to calculations, when climbing high peaks such as Mount Everest, the loss of blood moisture in the human body can be as much as 15-40% due to respiration. In high latitudes, the increase of blood red blood cells makes the blood thicker, which may increase the chance of frostbite. Moreover, dry wind is often associated with severe cold. In conventional mountaineering activities, in addition to carrying enough water, climbers often carry convenient and effective stoves to dissolve snow water and supplement the loss of human body water.
Judgment errors: The increase in altitude will cause some adverse effects on the human brain, causing instability in people's mood. It is prone to panic, resulting in misjudgments and even self-harm. These adverse factors are fully taken into consideration when preparing for climbing. Experienced mountaineering teams usually adopt a group climbing tactic after reaching a certain height. In this way, in the event of danger, the team members can work closely with each other, take care of each other and be motivated, overcome difficulties together, and bravely climb and descend safely.
