What are the tourist attractions in Chizhou?

Under normal circumstances, there is no altitude sickness in Ningxia. Altitude sickness only occurs at an altitude of 3000 meters. In Ningxia, except for Helan Mountain and Liupanshan Mountain, the main peaks are above 3,000 meters, and 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, staying time and physical fitness. Generally speaking, 50%~75% people in plain areas will have altitude sickness when they quickly enter the plateau above 3000m, but after 3~ 10 days of acclimatization, the symptoms will gradually disappear. The probability of altitude sickness is as follows: 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 not with female body mass index.
