Generally speaking, it is possible to have a plateau reaction from a low altitude to an area of more than 4,000 meters, but the performance is different in severity.
Plateau reaction refers to a series of stress reactions related to plateau hypoxia that occur in the body after entering a high altitude area from a low altitude area (e.g., a plain area, a lower altitude area, etc.). The plateau response is a physiological reaction that occurs when the body responds normally to environmental changes. Therefore, it is possible to have a plateau reaction if one enters an area that is more than 4,000 meters above sea level from a lower altitude.
Plateau reaction can have dizziness, headache, nausea, chest tightness, panic, vomiting and other manifestations, different people’s performance varies, and climbing speed, altitude, personal constitution and other factors related. If you feel unwell, you should rest immediately and go to the hospital.
