Most longevity areas are located in mountainous areas with an altitude of 1500m. After years of medical research, Zhang Jianqing, vice president of Qinghai Branch of Chinese Medical Association and president of Red Cross Hospital of Qinghai Province, also found this secret from many physiological indexes such as sleep, lung function and hematopoietic function: altitude 1500m is beneficial to brain health and body longevity.

According to the experimental study of physiological health, the altitude most suitable for human survival is 500-2000 meters.

It is generally believed that the altitude of 2000 ~ 2500 meters is the best altitude for athletes' plateau training, but for middle-aged and elderly people and pregnant women living in plain areas, it is not good for their health to reach this altitude at once.

Below 500 meters above sea level, it is humid and hot because of high air pressure, high air density and heavy burden on human body functions.
