Amazing discovery made American scientists in 2020. It turned out that over the past 150 years, the human body temperature has become much colder and continues to decrease every decade by 0.03 ° C.
What is the reason for the decrease in the main biomarker, and what was the standard in the XIX century?
«Temperature Standard» installed German doctor Karl Wunderlich
The scientist examined more than 25 thousand people. The study did not take into account the age and lifestyle of patients, as well as the time of day, when measurements were carried out, and therefore revealed only the average «on the hospital»
It turned out that the temperature of conditionally healthy residents of Central Europe was exactly 37 ° C. These observations still lie at the heart of modern medical thermometry, which says the mark at 37 ° C on a mercury thermometer labeled in red.
Researchers from the Stanford University made a new analysis and took the measurement points of the US residents of three historical eras: the middle of the XIX century, the middle of the XX century and the beginning of the XXI century.
The total number of readings from three sets of data was almost 700 thousand.
As it turned out, the body temperature in America once also made 37 degrees. However, for today’s day, the men «frown»
Thus, today, 36.4 ° C can be considered an average normal temperature. It is assumed that the indicators will fall on and by 2150 by the normal temperature for people will be exactly 36 ° C.
In addition, the result could affect the modern heating system, which maintains the same air temperature in the room all year round. Technologies just taught the body more economical to spend their energy.
It is worth noting that the inhabitants of Africa who are not spoiled by modern technologies, the average body temperature
