As the epidemic gradually eases, many "little positive people" have appeared in various places, so many people have experienced the stage of fever. Body temperature is the most important secret of human beings. The constant body temperature is the basis for the normal operation of cells and physiological functions in the body. But scientists have discovered that human body temperatures are changing—gradually dropping. What's going on?
Scientists regard 37 degrees Celsius as the normal standard for the human body, which has not changed for at least a hundred years. However, nowadays, human body temperature has gradually dropped, and the standard value has also changed. The standard has been lowered to meet the body temperature changes of most humans.
Scientists have shown through research that human body temperature has been declining rapidly over the past hundred years. Scientists have been tracking the body temperature of some humans since 2000 and found that every 10 years, human body temperature will drop by 0.03 degrees Celsius. In other words, after a hundred years, human body temperature has dropped by 0.3 degrees Celsius, and the difference between men and women is also more obvious. Men's body temperature has dropped by 0.58 degrees Celsius, and women's body temperature has dropped by 0.32 degrees Celsius. Therefore, men's body temperature drops faster than women's. This data also shows that human body temperature needs to be redefined and is no longer 37 degrees Celsius.
Why does it cause differences in body temperature? In fact, the value of 37 degrees Celsius is highly controversial. 37 degrees Celsius was the final result analyzed by German scientists after tracking 25,000 research subjects and conducting millions of body temperature tests. Since then, 37 degrees Celsius has been regarded as the normal standard for human body temperature and has not changed for a hundred years. Therefore, people believed that the test samples at that time were limited, and tens of thousands of people could not represent all mankind. Secondly, people at that time were different from modern people in terms of food, clothing, housing, transportation, and environment. It is inappropriate to continue to use the 37 degrees Celsius standard. Therefore, there are errors in this value from many aspects.
But it is not difficult to find that human body temperature is constantly changing, and it may become higher or lower. In the future, human body temperature may exceed 37 degrees Celsius, or may drop to 33 degrees Celsius. This also shows that human beings have actually been in the process of evolution. Human beings need to adjust their body temperature to adapt to changes in the surrounding environment. This is a subconscious adaptation of human beings to environmental changes, and regulating body temperature is the top priority.
Moreover, there are differences in the body temperature of different people, so the body temperature is a normal fluctuation range between 36.4-37 degrees Celsius. Generally speaking, as long as the body temperature exceeds 37 degrees Celsius, it is considered to be in a fever state, so the current standard of normal body temperature has been changed, and is generally based on 36 degrees Celsius. Moreover, the body temperature of different parts of the human body is also different. The body temperature of the armpit is closer to the true temperature of the human body.
Why does the temperature of human beings drop so much? In fact, there is no unified answer to this question. Scientists have analyzed that when the human body temperature is maintained at 37 degrees Celsius, the body can consume less energy to complete the body's balance. When the body temperature is too low, it means more energy is consumed. With the development of science and technology, human beings have gradually transformed from labor force to mental activity. This means that when the intensity of labor gradually decreases, the energy required by the body is also small. In order for the body to adapt to this change, body functions will naturally change. Therefore, a drop in body temperature becomes inevitable.
In fact, a drop in human body temperature will also have an impact on the immune system, and the body's immune system will decline. The main reason is that we cannot obtain more capabilities to support it, and the ability of to metabolize will also decrease. Generally speaking, a drop in body temperature is a blessing and a curse, and there is no absolute good or bad. However, body temperature, as an indicator of human metabolism, is often related to human health and lifespan.
However, everyone does not need to be afraid. The drop in body temperature will not cause direct harm. We can regard it as a means of regulating body temperature to adapt to the surrounding environment. After all, only when the body reaches a balance can the human body be able to live a healthy life without major problems. As for whether human body temperature will gradually decrease or increase in the future, it is unknown, but it will probably develop in the direction most conducive to human survival.
