The standard temperature of 37 degrees has become history.
65438+In 1950s, German doctor Carl Reinhold August Wunderlich (hereinafter referred to as "Carl") tested the axillary temperature of 25,000 patients, and after repeated tests, a set of human body temperature standards was finally established. According to the test data, the temperature of 25,000 patients is between 36.2 and 37.5, so 37 has become the standard temperature of human beings.
Carl's conclusion has been widely recognized by doctors and scientists all over the world, and it has been used to this day. However, the latest data of human body temperature research found that the standard body temperature of 37 has become history. Julie Parsonette, a professor at Stanford University School of Medicine, consulted a large number of temperature data of medical soldiers during the civil war and compared them with the data recorded in modern medical libraries.
They found and confirmed that after Karl put forward that the standard body temperature was 37 185 1 year, the body temperature of American citizens has been steadily decreasing, and now the average body temperature is only 36.6. Compared with the civil war, the body temperature of American men dropped by 0.59; The female body temperature dropped by 0.32;
After extensive research, Parsenet found that all over the world, adults have different degrees of hypothermia. In other words, the standard body temperature is 37, which is out of date.
Why does the standard human body temperature drop?
1) Humans are gradually adapting to the environment.
What changes have taken place in human society and the earth's environment since the standard human body temperature is 37? I believe we all know that climate warming is a trend of the current global environment. Human activities and a large number of greenhouse gas emissions made the global average temperature ratio 100 years ago increase by 0.48. In 2 1 century, scientists measured that the average temperature in the Arctic increased by 1.2 compared with 100 years ago.
The whole earth is getting warmer. In order to adapt to this high temperature, human beings began to slowly adjust their body temperature. As a result of the adjustment, the average human body temperature has steadily decreased in the past 100 years.
2) Metabolic rate decreased.
The metabolic rate of human body is closely related to body temperature, just like the engine of a car, the degree of fever is different when it runs at high speed and at low speed. If human beings want to maintain basic physiological activities, they need to consume energy through metabolism to generate heat. If the metabolism is fast, the body temperature will be higher. Just like when we exercise, our body temperature will rise.
Modern humans, on the other hand, don't love sports so much; Moreover, with the advent of the era of intelligence and information, the number of manual workers is greatly reduced. When human beings do not like sports, the industrial era of forging steel slowly passes, human exercise decreases, metabolic rate decreases, and body temperature decreases.
At the same time, the increase of obesity rate and the appearance of air conditioning are also one of the reasons for the decrease of body temperature. Obese people generally have metabolic problems, and air conditioners always keep the indoor temperature constant, which makes the body's temperature regulation center less sensitive. Both * * * have the same effect and also lower the body temperature.
3) The immune system is not so strong.
There is also a saying that the improvement of medical level leads to the abuse of antibiotics, which is the reason for the gradual decrease of human body temperature, which is directly related to immunity. With the use of some antibiotics, the human body no longer relies solely on its own immune system to destroy germs.
When people abuse antibiotics, their immune system is not exercised, so they are not so strong. The immune system is not so strong, and it also affects the body temperature. It is also said that it is because the medical level of human beings has improved and the inflammation in the body is not as much as before, so the body temperature has dropped.
It is a fact that the body temperature drops. Scientist: Not a good thing.
At present, the drop of human body temperature has become an established fact. Moreover, according to the existing research data, scientists have come to a less reassuring conclusion: human body temperature is steadily dropping by 0.03 every 10 year, and this situation will not stop in a short time, which is not a good thing.
Although this conclusion has not been confirmed, people should pay attention to it. If the body temperature continues to drop, it will not stop. When the average human body temperature is lower than 35, the speed of heat loss will be faster than that of heat generation, which is prone to danger.
When a person's temperature is below 35 for a long time, limbs and skin will be affected. Then the heart, kidneys and other organs fail to work normally, which ultimately affects the balance of the body system. Both cardiovascular system and respiratory system will fail because of hypothermia, which is fatal to human beings.
postscript
But we don't have to worry too much. Although the natural environment is changing, all animals, including people, are trying to adapt to the environment and have evolved more survival skills. Just like humans come down from trees and learn to use tools and fire. Perhaps one day in the future, 35 will become the standard body temperature of human beings, and human beings can adapt to the life with low body temperature.
