Old people are lower than young people, and women are lower than men; The incidence of altitude sickness is positively correlated with male body mass index, but has nothing to do with female body mass index, indicating that obese men are more susceptible. 50% ~ 75% people in plain areas have altitude sickness when they quickly enter the plateau above 3000m above sea level, but the symptoms gradually disappear after 3 ~ 10 days of acclimatization.
Psychological and physical training should be carried out before entering the mountain. If possible, it is best to carry out intermittent hypoxia stimulation and acclimatization exercise in the low-pressure cabin, so that the body can adapt to the low-oxygen 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.
