Altitude is an important factor affecting human health, because at this altitude, the altitude that is most beneficial to human health has the most suitable air pressure, the densest negative oxygen ions and the most comfortable temperature!
According to the international physiological and health experimental research, people who live in plain areas for a long time can only adapt to the reduction of oxygen partial pressure by 20%, and it will cause obvious discomfort if it exceeds this value. This is because the air pressure below 500 meters above sea level is high, the air density is high, and it is hot and humid, which has a heavy burden on human functions; On the other hand, in the plateau area above 2500m, the atmospheric pressure is low, and the oxygen content in the air is reduced, which makes it difficult for people to breathe and produces mountain reaction. According to the experimental study of physiological health, the altitude that is most beneficial to human health is 1200m ~ 1500m. This is because normal people's heart rate is 70 or 80 beats per minute, and when the altitude reaches 1200m, people's heart rate will increase to 15%-20%, that is, it will increase by 7- 10, or even about 15, and the heart rate will accelerate at a low intensity, which will not be particularly bad. On the contrary, it will make people's body have wonderful physiological, physical and chemical reactions: the heartbeat is accelerated 15-20%, which can promote and accelerate the metabolism of the human body, increase the amount of perspiration correspondingly, burn fat faster, and naturally play a role in losing weight, which is very beneficial to women's weight loss and shaping; Men's thyroid, adrenal gland and gonad functions will be more active, and many physiological functions will be enhanced. The air pressure caused by altitude directly affects all aspects of human physiological functions.
People are warm-blooded animals, and their normal body temperature is kept at around 37℃, which is the body temperature chosen by human beings after a long evolution in order to adapt to the temperature difference in nature. Through scientific research, according to the golden section method, the product of human body temperature of 37℃ and 0.6 18 is 22.8℃, that is, when the environmental temperature is about 18℃-25℃, people are most comfortable, because at this environmental temperature, human metabolism, circadian rhythm and physiological function are in the best state. At the same time, the human body needs a certain intensity of phased environmental temperature changes to improve the self-regulation and purification functions of the human body and its adaptability to the environment. The maximum limit of the staged temperature change is not higher than 37℃ and the minimum is not lower than 4℃. If it is too high, it will easily lead to excessive loss of nutrients due to evaporation. If it is too low, it will affect the metabolic rate below freezing point and easily lead to slow action. The altitude 1200m just meets the above environmental temperature conditions: the average natural temperature is kept at 15℃-25℃ from April to1October every year, lasting for half a year, and the average temperature in the coldest winter (12 to February of the following year) is around 6℃-8℃. Therefore, this higher ambient temperature is most conducive to the benign operation and normal regulation of the human body, promoting health and longevity, and is very suitable for modern people, especially middle-aged and elderly people, to live, live and preserve their health for a long time.
