Earlier, 4 prospectors entered the Ailao Mountain to operate, but they lost contact. Although rescue teams were also dispatched urgently, unfortunately, after the discovery, 4 explorers were killed, 3 of them fell in similar positions, and the other went a little further.
As for the cause of the death, according to the description of the search and rescue personnel at that time, there was a prospector with a soft facial expression and a shirt that had been lifted, which was in line with the characteristics of death from temperature loss. However, the majority of netizens did not buy it, thinking that the cause of death was other than that, and they thought it was important that 3 of the victims fell in similar positions. If it is out of temperature, it is impossible for everyone to fall down quickly, and they did not turn on the positioning equipment at that time, so they thought that death was strange, and it must be a factor that made them unable to react.
According to search and rescue personnel, before the final fall, the four prospectors got lost in an area, walked back and forth several times, and they were not far from a break in the middle. Some netizens speculated that they encountered the so-called miasma, and some people believe that the miasma is probably a toxic gas produced by corruption in the woods, and if it is encountered in an instant, it may indeed cause several people to fall down quickly. But miasma refers more to the pathogen of blight, and the concentration of toxic gases in forests is very low due to the respiration of plants.
And highly toxic poisoning will also have some special signs, such as cyanide poisoning will be iron blue, the mouth has the taste of bitter almonds; hydrogen sulfide poisoning will cause cyanosis, that is, lips and facial bruises and other manifestations, due to lack of oxygen asphyxia may also cause scratches on the surface of the body. There are no such signs on the remains of the four victims of Ailao Mountain. According to the Natural Resources Comprehensive Survey Command Center of the China Geological Survey, the public security organs conducted a forensic examination on them and also confirmed that they were killed because of the loss of temperature.
The loss of temperature in the usual view of the occurrence is very slow, after all, people are very autonomous creatures, cold to know to find a hidden place or wear more; there are also people feel that the temperature loss must be a very low temperature, in fact, not, the temperature loss generally refers to the external temperature is significantly lower than the body temperature, for a long time in a low temperature environment and insufficient warmth, it will cause the body heat is not a loss, and eventually lead to temperature loss. In the temperature of about 10 ° C, the temperature loss can already occur, and the harm of temperature loss also has a certain concealment.
When the four geologists of Ailao Mountain entered the mountain to investigate, although they had storm jackets, heating supplies, etc., the temperature of the local surface was still more than ten degrees. However, the night temperature on the mountain will be lower, and those who have studied secondary school geography know that the mountain is rocky, and the rock dissipates heat quickly than the heat, and the temperature will decrease with the increase in altitude, about 0.6 ° C per 100 meters. Unfortunately, it was raining at that time, and in the temperature of only a few degrees on the mountain, it was difficult to make a fire in the wet and cold environment, and the clothes were wet, and it was easy to lose temperature.
According to the medical test of the public security organs, 4 people died of cardiogenic shock caused by low temperature, excluding poisoning and mechanical injury. The main reasons for the death of 4 people are: excessive physical exertion caused by long-term climbing, instantaneous winds in the area of the incident, and sudden drop in temperature caused by human body temperature loss. This is like a marathon in Gansu, China, the weather itself is very good, the temperature is also suitable, but there is a section of road in the mountains, the local sudden wind cooling weather, soon caused more than 20 people killed in the accident, the temperature loss is sometimes difficult to prevent.
The concealment of the temperature loss may cause people to react in a timely manner. Temperature loss is initially to feel cold, but if people are active, they can also generate some heat to make up for the lost heat, but the low temperature plus the loss of temperature will cause the person's response to decline, the arms and legs have some stiffness, and then the skeletal muscles of the body in order to generate more heat involuntarily tremble, this process may be very fast, only a few minutes of time, affecting the person's fine operation. At this time, the brain's response further declines, which can lead to a misjudgment of one's own situation.
The subsequent temperature loss is even more dangerous, when the body temperature drops below 35 ° C, the consciousness is dazed, the limbs are stiff, and the coordination of movements begins to be lost, especially in the hands, such as not being able to zipper. The cause is insufficient blood flow to the periphery. Slurred speech, violent shaking, behavioral disorders, for example, starting to undress but not feeling cold yourself. Abnormal undressing in the absence of temperature often occurs at this stage. After that, the body temperature is no longer known for 33 ° C, but the process is terrible.
Once a person enters the final severe loss of temperature, the blood is constantly redistributed in the body, sometimes feeling warm and soothing, sometimes feeling very cold and shaking violently. But at this stage, there is also salvation, but once lost in the wild, you can only wait for search and rescue, but after all, the search and rescue will be delayed for a long time, and people can not carry it for long in a detemperature environment. Extremely low body temperature can cause breathing, a decrease in heart rate, and eventually heart arrest, respiratory arrest and other events, which will cause death.
In the current season, if you do not get warm outside at night, it may also cause a loss of temperature. What needs to be reiterated again is that it is not only the extreme low temperature that will cause temperature loss, but also the factor that will accelerate the loss of human heat, generally in a lower temperature environment (can be the temperature below 10 ° C), if there is moisture evaporation (clothes are wet), high winds (accelerating the flow of air on the surface of the body, taking away a lot of heat) and other factors, human body heat will be rapidly lost.
