From UPSC perspective, the following things are important :
Prelims level : “Normal” body temperature
Mains level : NA
For several years now, doctors and researchers have known that 98.6°F is not really the gold-standard “normal” body temperature it was once considered to be.
The “normal” body temperature
- In 1851, Carl Reinhold August Wunderlich pioneered the use of the clinical thermometer.
- It was a rod a foot long, which he would stick under the armpits of patients at the hospital attached with Leipzig University, and then wait for 15 minutes for the temperature to register.
- He took over a million measurements of 25,000 patients, and published his findings in a book in 1868, in which he concluded that the average human body temperature is 98.6°F.
- Most modern scientists feel Wunderlich’s experiments were flawed, and his equipment inaccurate.
- Another study concluded that the average human body temperature is closer to 98.2°F, and suggested that the 98.6°F benchmark be discarded.
- Studies in the US and Europe have found average body temperatures declining over time.
- In recent years, however, different studies have found the human body temperature averaging out differently, including at 97.7°, 97.9° and 98.2°F.
- One of the largest such studies, published last year, found that body temperatures among Americans have been declining over the last two centuries.
