Plateau reaction has a certain degree of danger, and the degree of danger is determined by factors such as individual physical fitness and the altitude of the plateau. The high cause is higher altitude and thinner oxygen, so it is easy to have plateau reaction in a plateau environment. For people with good physique, the symptoms of plateau reaction are mild, may appear slight dizziness, nausea and other symptoms, generally will get better after adaptation. However, if you have a weak constitution and are at a high altitude plateau, you may experience breathing difficulties, pulmonary edema, etc. Therefore, plateau reaction is dangerous. After being in the plateau, must pay attention to not strenuous exercise, to avoid intense oxygen consumption, thus causing severe hypoxia. In addition, after the plateau reaction can eat some rich in vitamin E fresh fruits and vegetables to ease the symptoms. In the more serious plateau reaction, must consult a doctor in time to avoid delaying the condition.
