The contestants of Gansu Mountain Marathon accepted an exclusive interview with CCTV. What did he say?

On May 22nd, the Yellow River Shilin Mountain Marathon held in Jingtai County, Baiyin City, Gansu Province suffered from extreme weather, and 2 1 person was killed. The Gansu Provincial Party Committee and the provincial government have set up an incident investigation team to further investigate the cause of the incident.

Contestants wear thin clothes, and people keep dropping out of the competition. Cyndi Luo, a contestant, accepted an exclusive interview with a reporter from the main station. Cyndi Luo is an outdoor sports enthusiast and the only female mountaineer in China who has climbed 14 8000m high mountains. As a professional, she recalled the situation at that time.

After being in a coma for two hours, he was rescued by the villagers. After being in a coma for two hours on the mountain, he was rescued by the villagers. "He took me to the cave and made a fire." After that, Zhang Xiaotao gradually regained consciousness.

The evaluation of the accident was mainly due to the high wind speed and humidity at that time. High wind speed quickly takes away the heat from the skin, and the temperature in the body is quickly replenished, but the speed of replenishment can't keep up with the speed taken away by high wind speed, which eventually leads to the temperature drop in the core area; Another factor is the high humidity in rainy days, which accelerates the rate of heat conduction and its temperature loss. Another is that the exposed area of human skin is too large, which leads to the accelerated temperature loss.

Only when the temperature is below zero can people not freeze to death. As long as our bodies dissipate heat too quickly and lose temperature, even in summer, people may be "frozen to death".

Only when the outdoor temperature is below zero will people not freeze to death. Even in mild spring, people will die if they encounter symptoms of hypothermia. Severe hypothermia will kill you if you don't save it.

Evaporation means that liquid water becomes gaseous water (steam), which will absorb a lot of heat. This is called "evaporation to absorb heat", and this phenomenon is more obvious if there is water and sweat on the skin. Therefore, in the case of strong wind, it accelerates the convection of the skin on the body surface and accelerates the evaporation and heat absorption. The outside world keeps taking away a lot of heat from the human body. The stronger the wind, the more heat it takes away. Once the speed of taking away heat is greater than the speed of generating heat by human body, it will "lose temperature".

Among the hazards of extreme weather in outdoor activities, temperature loss is a more dangerous one, because the arrival of temperature loss is "hidden" and we can easily ignore it, but its consequences are the most "fatal".

Uncontrollable jitter when outdoor encounters the first-stage temperature loss. We need to get warmer in the first place. Find a sheltered place, keep warm with warm equipment, and then take off your wet clothes. For example, in Gansu Marathon, many runners make a fire in the hut to keep warm. Uncle Shepherd found that it was the right thing to do for the unconscious man to take off his wet clothes at the first time.
