150, the body temperature will drop by 0.45 degrees Celsius. Will humans become frozen people in the future?

The human body temperature drops by 0.03 degrees Celsius every 10 year, and so on. 150 year is equivalent to a temperature drop of 0.45 degrees Celsius, and this data of body temperature change mainly selects 600,000 people as the research sample.

The research results of Harvard university experts have been successfully published in the important magazine Elifesciences. Although humans are indeed warm-blooded animals, this does not prevent scientists from studying the temperature changes of the human body. Moreover, according to the research data, in the past 150 years, human body temperature did change with time.

However, this change will not cause people to become gradually frozen after a long time, but because the quality of life of human beings has been greatly improved, and the body has reduced some discomfort, which will lead to an overall decline in body temperature. Moreover, the so-called warm-blooded animals do not mean that the absolute value of body temperature is constant in the true sense, but only because these biological species have a relatively perfect body temperature regulation mechanism, which enables them to maintain a relatively stable body temperature state in different environments.

We often say that body temperature refers to the temperature inside the human body. In essence, the constant body temperature depends entirely on basic metabolism. In short, the relatively constant body temperature under normal circumstances is actually the result of the transformation of material metabolism into heat energy. Once the body temperature rises, the body will automatically keep the body temperature constant by increasing heat dissipation, and whenever the body temperature drops, the body will maintain the normal level of the body temperature by increasing heat production.

Even what we usually call normal body temperature is not a specific temperature value, but a relatively stable range value: the underarm temperature ranges from 36 to 37 degrees Celsius, the rectal temperature ranges from 36.5 to 37.7 degrees Celsius, and the oral temperature ranges from 36.3 to 37.2 degrees Celsius. We can ignore that the order of magnitude of the research sample is very small, and the total temperature drop of human body in 150 years is less than 0.5 degrees Celsius.

Moreover, even these so-called normal body temperature standards are only applicable to most people, not every human individual. This is also the fundamental reason why some people's body temperature will be significantly lower than the average normal body temperature. Moreover, when we measure the temperature at different times of the day, we can also find that the results of each measurement may be slightly different. At the same time, for men and women, women's body temperature is often about 0.35 degrees Celsius higher than that of men.

As for human body temperature, we should know that its value is not fixed. Our age, sex, mood, measuring time and whether we are exercising or not will all affect the result of thermometer measurement. Newborn children are particularly vulnerable to the influence of external temperature, and their body temperature is always slightly higher than that of us adults. Older people with relatively low metabolic rate tend to have lower body temperature.

As far as measuring time is concerned, the lowest temperature can be measured in the morning (2:00 ~ 5:00) and the highest temperature can be measured in the afternoon (5:00 ~ 7:00), and the temperature fluctuation range of these two time periods is generally around 0.5 ~ 65438 0 degrees Celsius. Of course, whether the outside temperature changes greatly or the food we eat is spicy, it will lead to fluctuations in our body temperature.
