Always if the temperature of the human body were the same?
Source:Normal average body temperature is considered to range from 35.5 to 37 degrees Celsius
Almost two centuries ago, the experts were able to calculate the normal human body temperature, which was about 37 degrees Celsius. For many years this figure was considered “normal” body temperature for being the positive state of his body. But could the normal shift for the modern man under the pressure of many factors, among which can appear on the state of the environment and even climate change? By posing this question, the researchers conducted a number of studies, the results of which may surprise even the most inveterate skeptic.
Average temperature of the human body
Since each organ in our body has an individual optimal temperature level, whose range can vary up to several tenths of a degree, is not the same everywhere. So, for example, by measuring the temperature orally (by mouth) healthy man gets 37 degrees Celsius, and measuring the temperature axillary (in the armpit), gets the same 36.6 degrees. Experts say that the average body temperature is always affected by many factors, among which stand out the age, height, gender and weight and activity level of the person, his diet and even weather conditions. In addition, the researchers also found that there is a body that can move at 0.2 degree Celsius during the day. Therefore, the range of accepted norms is quite flexible and suitable for every body, varying from 35.5 to 37 degrees Celsius.
Why falling average temperature of the body of mankind?
According to an article published on the website , the human body maintains a relatively stable temperature level in order to maintain the health of organs and vital systems, and also to prevent the development of various fungal infections. After studying the statistics of average temperature of the human body, scientists came to a startling conclusion: the body temperature of a modern person is different from the temperature characteristics of his ancestors. Why is this happening?
Scientists have identified a decrease in the average temperature of the body the modern man.
A Team of scientists examined data that included information since the civil war of 1970 in America and the early 2000s. Thanks to the combined information, the scientists were able to collect 677 000 measurements of body temperature. In the study, scientists have identified a natural reduction of temperature indicators, showing that approximately every decade the temperature is reduced by 0.02 degrees Celsius. Thus, men born in 2000 years, the body temperature lower by 0.58 degrees Celsius, than men born in the early 1800-ies. Incidentally, this trend has affected not only men but also women. So, the fair sex, who were born in 2000-ies, have an average body temperature is less than 0.32 degrees Celsius than women born in the 1800-ies.
A Team of scientists who noted a steady decrease in the average temperature of the human body, also took into account the possibility of distortion of data because of improvement of technologies thermometry by studies of individual dataset. However, as a result of further studies, data showing the trend of “cooling” of the human body, was confirmed regardless of the types of thermometers used in a particular historical group.
Scientists suggest that this downward trend in average body temperature may have several causes. One of the most likely is a reflection of the historic reduction in humans, including excessive inflammation in his body due to the impact of a large number of pathogenic microorganisms. The second most likely reason could be the decrease in the intensity of heavy physical labor, as well as the establishment of favorable habitat conditions. Despite the results of the studies that have been conducted in the USA and the UK, in some countries, this trend is not marked.
