What are the symptoms after staying in the Qinghai-Tibet Plateau for 24 years and returning to the mainland?

People who live in high altitude areas for a long time will also have adverse reactions in inland areas, which are collectively called "drunkenness". Because the human body has adapted to the anoxic environment in the plateau and re-entered the area with relatively high oxygen content, maladjustment will occur again, and symptoms such as fatigue, fatigue, drowsiness, chest tightness, dizziness and diarrhea will occur, resulting in so-called "maladjustment reaction" or "low original reaction". In medicine, it is also commonly known as "drunkenness".

The reason of "drunkenness" is that in order to adapt to the anoxic environment, the oxygen carrying capacity of compensatory red blood cells is enhanced to meet the needs of the body. When people return to the plain from high altitude, the oxygen content in the air increases, and the body has not adapted to this high oxygen environment. Red blood cells are still delivering oxygen with high efficiency and high quality, so they will be "drunk". There is no need to panic in this situation. "Drunk oxygen" is generally not serious. The doctor suggested, "Come back and rest for a few days before working, and you will recover." In addition, it is possible to "gradually retreat" if conditions permit, and to adopt a "gradual" evacuation method from high altitude areas will help alleviate "drunken oxygen".
