Indigenous Group In Amazon Drop In Body Temperature

New research detected an intriguing change in the average body temperature of the Tsimane people, an indigenous foraging and farming group in the Bolivian Amazon that has recently started to interact more with industrialized communities. Over 16 years, the Tsimane have experienced a slight but rapid drop in body temperature—mirroring a similar decline seen among Americans over the past century and a half. This January, a study found evidence in well-maintained medical records that the body temperature of Americans has dropped roughly 0.05 Fahrenheit every decade since the 1860s.
