Is it true that Kunming has four seasons like spring? Could it be altitude sickness?
Generally speaking, people who live in plain areas for a long time can only adapt to the reduction of oxygen partial pressure by 20%, and if it exceeds this value, there will be obvious discomfort. The most suitable altitude for human survival is 500-2000 meters. Therefore, traveling to Kunming generally does not cause altitude sickness, and many so-called altitude sickness are caused by psychological effects. As long as you have a happy mood, you can effectively alleviate the occurrence of altitude sickness.
Warm reminder:
Although the altitude of Kunming will be higher than that of some low-altitude areas, it will not have much impact on people's adaptability, so there will generally be no altitude sickness, so you don't have to worry. What should I do if I encounter altitude sickness during my trip? As long as you take oxygen in time and pay more attention to rest, it can be alleviated.
