The body works like an automatic furnace, which heats up and cools down to maintain a constant temperature. When itputs out a lot more or a lot less heat than usual, the body may be trying to tell you there is a problem. It is when we go to adoctor or a pharmacist.   For more than 100 years, 98.6℉ has been considered the norm al hum an body tem perature. B ut recently, a StanfordUniversity research study, based on some 677,000 temperature readings collected from 190,000 people, points out that from1862 to 2017, the human body temperature fell by 0.054℉ and 0.052℉ per decade for m ales and fem ales, respectively.   The change in average height and weight is the possible explanation for some of the decline, because nowadays peoplehave better nutrition, medical service, and public health. Most importantly, the effective use of antibiotics and vaccines controlmany of the inflammatory conditions that can drive up body temperature. The function of inflammation is to eliminate thecause of cell injury and initiate tissue repair. Besides, when people are ill, they usually take nonsteroidal anti-inflammatorydrugs and statins to fight inflammation, therefore preventing the body from heating up.   The findings suggest doctors should practice more personalized temperature readings that take all the things that affectbody temperature into consideration, such as height, weight, age, time of day and outside temperature.
