Will children have altitude sickness when they go to places above 4000 meters above sea level? How to prevent it?

How old is the child? If you are younger, I suggest not going. For safety reasons, there will be altitude sickness at 4000m, which is generally difficult to prevent. The occurrence of altitude sickness is related to the oxygen threshold of human body and varies from person to person. This is a normal physiological manifestation. If you have altitude sickness, you can take anti-altitude sickness health care drugs, such as Omo to carry oxygen, increase blood oxygen content and improve blood oxygen utilization rate to alleviate altitude sickness.
