The idea that the standard human body tempera⁃ture is about 98.6℉(37℃)was first presented by the German physician Carl Reinhold August Wunderlich in 1851.Since then,its become so widely accepted that it serves as a touchstone for health—a diagnostic tool used by physicians as a basic indicator whether someone is sick or well.However,it turns out that this well⁃established fact isnt,in fact,correct—or,to put it more accurately,human beings have been getting cooler over the years.
