Will the elderly have altitude sickness when they go to Yunnan?

Old people may have altitude sickness when they travel to Yunnan.

The elderly may face the risk of altitude sickness when they travel to Yunnan. Altitude sickness is a series of physical reactions caused by high altitude and hypoxia, including headache, dyspnea, fatigue, nausea and other symptoms. Due to the decline of lung function, the elderly are more sensitive to hypoxic environment and are more prone to altitude sickness. Yunnan is high in the north and low in the south. Most areas are between 600 and 3000 meters above sea level, with an average elevation of 2000 meters. If the elderly quickly climb to the plateau above 3000 meters above sea level, or stay in high-altitude areas in Yunnan, such as Yulong Snow Mountain and Meili Snow Mountain, their risk of altitude sickness will increase. Therefore, the elderly should pay attention to the possibility of altitude sickness before traveling to Yunnan, and take appropriate preventive measures, such as gradually adapting to high altitude environment, avoiding strenuous exercise and maintaining adequate water intake.
