A driver said: "In the no-man's land on the Qinghai-Tibet Plateau, don't make a fire to keep warm at night, no matter how cold it is." Why?

The driver told tourists that in the no-man's land on the Qinghai-Tibet Plateau, even if it is very cold at night, don't burn a fire to keep warm, because burning a fire requires oxygen, and the local average altitude is as high as 4,000 meters, and the oxygen is very thin. If the fire consumes too much oxygen, you may feel particularly uncomfortable here, and even lack oxygen, so try not to burn the fire to keep warm at night. Moreover, the Qinghai-Tibet Plateau is a no-man's land, and the terrain here is particularly complicated. The environment in many areas is unpredictable, so you must be prepared in advance to go here.

The overall environment of the Qinghai-Tibet Plateau is very dangerous, so few people come here. In this case, no man's land has become a world of animals and revelry. These animals can move freely in no man's land without any restrictions. Therefore, if you want to spend the night here, you have to take a lot of risks. Many animals may come out for food at night, and fire may attract many animals, which is also a dangerous situation.

After coming here, it is easy to have altitude sickness. If you make a fire in a place where oxygen is thin, it is likely to consume too much oxygen. Everyone has a headache and insomnia because of the thin oxygen. If the fire is still burning at this time, the oxygen in the human respiratory tract may be reduced, which will make the altitude sickness of the body more and more serious. Moreover, it is difficult to ignite successfully here, so it is possible to consume more exercise in this process.

If you sit quietly and breathe normally, there may not be such a big problem, but running around looking for firewood to make a fire may consume more oxygen, so your body will become more uncomfortable. If carbon monoxide poisoning is caused by fire heating, the situation at the scene will be more serious. So I hope everyone must be prepared before coming here and don't make a move.
