Altitude sickness refers to the pathophysiological reaction caused by hypoxia when an individual enters a high altitude area from a low altitude area in a short time. There are many factors leading to altitude sickness, such as environmental factors, entry mode, psychological factors, physical condition and preventive measures. Fully prepared, most people can have no altitude sickness, or they can have a slight high reaction.

First, don't think too much about altitude sickness. Being too nervous or excited will increase the oxygen consumption of brain tissue, neither anoxia nor anoxia.

Secondly, take health foods that can improve hypoxia tolerance before departure, such as Gao Yuan 'an and Rhodiola. Effective health food focuses on prevention before illness. Don't wait for altitude sickness before thinking about taking such products. After arriving at the plateau, pay attention to control diet and exercise. When you first arrive at high altitude, don't be too full or hungry, walk slowly and speak softly.

In case of severe hyperreflexia, it is recommended to take oxygen or choose a regular hospital for targeted treatment. Don't delay the treatment time, but don't take oxygen inhalation and other treatments as general prevention. Short-term oxygen inhalation can only relieve discomfort, can not help the body adapt to the plateau environment, and is easy to form dependence.
