What is the most suitable altitude for human habitation and survival?

Geographical experts at home and abroad have found that the most suitable altitude for human survival is about 500 meters to 2000 meters, while the Xichang urban area is about 1500 meters, and the Qionghai Lushan Scenic Area is 2044 meters, which is the most suitable for human habitation.

Medically speaking, men at 1500 meters help to promote their thyroid, adrenal glands, gonadal function to be further active; And this altitude makes women more beautiful. Moreover, through medical and bodybuilding experts in junior high school, it is concluded that the altitude of 1500 meters is conducive to women's body shaping, and the dense negative oxygen ions here not only make the hair smooth, shiny and elastic, but also have an excellent role in promoting women's beauty and appearance. In addition, this height can increase the heart rate of women by 15%-20%, and emotional thinking greatly exceeds rational thinking.

Human instincts are maximized at this height, making it an ideal romantic paradise for couples.

Hello, human physiology and hygiene experiments have found that the most suitable altitude for human survival is "500 2000" meters. 500 meters low altitude, 2500 meters medium altitude, 3500 meters high altitude.

1500 meters is a low altitude altitude, and after scientific research on physiological changes, starting from 1500 meters above sea level, every 100 meters above sea level will increase the heartbeat by 15% 20%. Altitude has a great effect on the human body. Before, my basic understanding was:

The higher the altitude, the less dense the air, the more difficult it is for humans to breathe, and because they are accustomed to normal air pressure, when they get to high altitudes, blood flow will slow down, and they will feel very suffocated, and the higher the altitude, the more difficult it is to cook. Some people get nosebleeds.

Hello AWSL] because seeing that you didn't rate me last time, I am very concerned about your experience. If you are satisfied with my service, I hope you can give a thumbs up! If you are not satisfied with my service, you can also click on my avatar and tell me in a private message, and I will definitely give you a satisfactory experience in the next service!

Experimental studies of human physiology and hygiene have found that the most suitable altitude for human survival is "500 2000" meters. 500 meters at low altitude, 2500 meters at medium altitude and 3500 meters at high altitude. 1500 meters is the low altitude.

After scientific research on physiological changes, starting at 1500 meters, for every 100 meters above sea level, the heartbeat increases by 15% 20%. Altitude has a great effect on the human body. In the past, my basic understanding was that the higher the altitude and the less dense the air, the more difficult it was for humans to breathe.

And, because I'm used to normal air pressure, when I go to a place at a higher altitude, the blood flow slows down and I feel suffocated. And, the higher the altitude, the more difficult it is to cook. Some**nosebleeds.

The mountain climate above 1500 meters above sea level has low oxygen partial pressure, strong solar radiation, so the ultraviolet rays are sufficient, which greatly reduces the probability of human respiratory diseases, although the average daily temperature at this height is lower than the plain, but the airflow activity is less, although there is fog on the mountain, but the actual water vapor content is less, therefore, the winter is warm and the summer is cool, less dust and less bacteria, the air is fresh, and the infection and occurrence of respiratory diseases can be reduced.

The most suitable altitude for human survival is 500 meters to 2000 meters, about 1500 meters in Zuocheng District, and 2044 meters in Qionghai Lushan Scenic Area, which is the most suitable for human habitation.

It is best for the elderly around 1500 meters.

Most of the longevity zones are located in the mountains at an altitude of 1,500 meters. After years of medical research, Zhang Jianqing, vice president of the Qinghai Branch of the Chinese Medical Association and president of Qinghai Red Cross Hospital, has also discovered this secret from the investigation of many physiological indicators such as sleep, lung function, and hematopoietic function: an altitude of 1,500 meters is conducive to the health of the brain and the longevity of the body.
