video 5'43 : https://youtu.be/1Scf7ZJcPUY?si=0d_KVoTXCobnig5p In 1851 a German doctor named Carl Wunderlich conducted a yearslong study. He went room to room in his hospital with a thermometer, taking the temperatures of some 25,000 different patients to try and pin down the average human body temperature. And he did, seventeen years later, when he published a paper with that well-known metric of 37 degrees! He also gave us the first quantitative measurement for determining if someone has a fever. 38 degrees and above. And then for the next 140 years, we just accepted this number as correct. Despite the fact that Dr. Wunderlich collected this data using a comically large, foot-long thermometer that had to be held in a patient’s armpit for 20 minutes. Because believe it or not, portable thermometers small enough fit under your tongue weren’t invented until 1866. So it wasn’t until the 1990s that another doctor decided to revisit this question using more modern equipment. And he found that yeah, the average human body temperature is ACTUALLY around 36.8 degrees Celsius.
