Under normal circumstances, altitude sickness will not occur in Ningxia.

Altitude sickness only occurs at an altitude of 3,000 meters.

In Ningxia, apart from the main peaks of Helan Mountain and Liupan Mountain exceeding 3,000 meters, other places are generally around 1,100 meters above sea level, so altitude sickness usually does not occur.

The occurrence of altitude sickness is related to climbing speed, altitude, stay time, and physical fitness.

Generally speaking, 50% to 75% of people in plain areas will develop altitude sickness when they quickly enter a plateau with an altitude of more than 3,000 meters. However, after 3 to 10 days of getting used to it, the symptoms will gradually disappear.

The probability of altitude sickness is as follows: the elderly are lower than young people, and women are lower than men; the incidence of altitude sickness is positively correlated with the body mass index of men, but not positively correlated with the body mass index of women.
