Witnesses of the Yellow River Stone Forest Marathon described the feeling that the temperature dropped. What is temperature loss?

Human beings are warm-blooded animals, which should not be higher than 37.3℃ or lower than 35℃ under normal circumstances. Once the body temperature drops below 35℃, it is hypothermia. If the human body loses its temperature, it will make the client's consciousness turbid, but when the temperature loss is serious, he will take off his clothes. It's like a movie, where someone is locked in the freezer for a while. First of all, they feel cold. After losing the temperature, the human body will feel burning. After undressing, the risk of cardiac arrest will increase.

Marathon runners feel the temperature, the specific situation.

On the day of the game, it was sunny at first, and I didn't feel cold. In the afternoon, there was a breeze of four or five. After running for 2 kilometers, it was not as hot as usual. After running for a while, it began to rain. Because it is against the wind, rain will hurt your face. It's raining harder and harder, and my eyes are blurred. I was also shaken to hear that some players around me chose to retire, but I thought 1600 yuan would be wasted, so I persisted for a while.

After climbing the mountain, my fingers were numb and my tongue was stiff. At this moment, I finally gave up the game, but it was easier to go up the mountain than down it. I walked back carefully. At that time, I was already at a critical point. If I don't make a decisive decision, I will probably fall like other players. Halfway up the mountain, I saw a blue rescue team searching and rescue. At this moment, I realized that something must have happened.

What caused the temperature loss?

Hypothermia has two main causes. 1 Being in an extremely low temperature environment for a long time. The second reason is that alcoholism causes the body to automatically inhibit heat production, and there is no heat for the human body to drop rapidly. Some people with poor constitution, such as anorexia and hypoglycemia, will also have hypothermia.

Most marathoners lose their body temperature for environmental reasons. At that time, there were not only strong winds and freezing rain, but also the higher the altitude, the less oxygen. Every athlete is wearing sportswear. When he feels cold, he can't wear a cotton-padded jacket or hide in the quilt. He can only bite his teeth and walk forward or backward.
