Extended data
The occurrence of altitude sickness is related to climbing speed, altitude, staying time and physical fitness. Generally speaking, 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.
The incidence of this disease is lower in the elderly than in the young, and it is lower in women than in 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.
