Why is there altitude sickness?
The reason for the formation of mountain sickness is that the higher the altitude, the thinner the air and the lower the air pressure, so the oxygen pressure required by the human body also decreases, but the oxygen content required by the human body remains unchanged. In order to maintain the oxygen content needed by human body in blood, it is necessary to increase the content of red blood cells, but it takes several days for human body to automatically increase the content of red blood cells.

So when I first entered the mountainous area, the oxygen supply in my body would be insufficient because of my sudden height increase. The higher the height, the shorter the transition time and the more intense the reaction. This physiological reaction is generally called "mountain sickness".

Before entering the mountain, both psychological and physical qualities should be adapted. If possible, it is best to carry out intermittent hypoxic stimulation and acclimatization exercise in the low-pressure cabin, so that the body can have certain physiological adjustment to the hypoxic environment from the plain to the plateau.

At present, it is considered that climbing is the safest and safest way to prevent acute altitude sickness except those who are particularly prone to hypoxia. Experts suggest that novices who want to enter the plateau above 4000m usually stay at 2500 ~ 3000 m for 2 ~ 3 days, and then the rising speed should not exceed 600 ~ 900 m every day.

After arriving at the plateau, avoid drinking alcohol and taking sedatives and hypnotics for the first two days to avoid heavy physical activity. Light activity can promote adaptation to the environment. Avoid cold and freeze, pay attention to heat preservation, and advocate the use of high-carbohydrate diet. Avoid alcohol and tobacco, and take sedatives and sleeping pills to ensure adequate liquid supply.

The use of acetazolamide, dexamethasone, acanthopanax senticosus, compound codonopsis pilosula and sulpiride before going up the mountain may be effective in preventing and relieving symptoms of acute altitude sickness. Patients with organic diseases, severe neurasthenia or respiratory tract infection should not enter the plateau area.
