Medical experts and scientists are re-evaluating the long-held standard of 36.6 37 degrees Celsius as the universal normal human body temperature. Research suggests that healthy temperatures fluctuate within a broader range based on factors such as age, time of day, physical activity, and measurement methods. A study led by Stanford University involving data from nearly 190,000 individuals in the US between 1862 and 2017 analysis of more than six million datasets indicates that the average body temperature has declined since steadily over the 19th century. last two centuries. The findings suggest a decrease of approximately 0.03 degrees Celsius per decade. While the current 37 degrees Celsius standard was established in the 1860s by German physician Carl Wunderlich, modern data suggests the actual average for healthy adults is now closer to 36.39 degrees Celsius. Specific demographic data shows that men born in the 1990s have an average temperature roughly 0.59 degrees Celsius lower than men from the early 1800s. For women, the decline compared to the late 19th century is approximately 0.32 degrees Celsius. Scientists propose that improved public health, better hygiene, vaccinations, and climate-controlled environments may contribute to this decline, as the body no longer needs to generate as much metabolic heat to combat frequent infections. Recent analysis highlights that the 37 degrees Celsius standard was established in the 19th century by German physician Carl Wunderlich. However, data shows the average temperature for American men has dropped by approximately 0.59 degrees Celsius compared to the early 19th century. Similar downward trends have been observed in other populations, including the Tsimane community in the Bolivian Amazon. chronic infections, such as tuberculosis.
