Altitude sickness varies from person to person, because everyone has different oxygen consumption thresholds. The lower the oxygen consumption threshold, the better his tolerance to altitude sickness.
Under normal circumstances, people living in the plain will have altitude sickness when they reach 3000 meters, and people with low oxygen consumption threshold will have altitude sickness when they reach 4000 meters.
People living on the plateau generally don't have altitude sickness.

Prevention of altitude 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.
