To find out what really happened, Parsonnet and her team combined three data sets. The first set covered nearly 24,000 Union Army veterans( 老兵) from the American Civil War, whose temperatures were measured between 1860 and 1940. The other two ranged from 1971 to 1975 and from 2007 to 2017. In total, the team analysed more than 677,000 temperature measurements.

On average, US body temperature has dropped by 0.039C per decade. Body temperatures of men borm in the early 19th century were 0.59°C higher than those of men today. Women's average temperature has dropped by 0.32°C compared with that of women borm in the 1890s. That means average body temperature today is about 36.6°C, not 379C as it is widely thought.

The change isn't simply the result of older thermometers(温度计) being unreliable. We know this because the cooling trend is visible within the more modern data sets, in which the thermometers were probably more accurate.

“The most likely explanation in my view is that, microbiologically, we're very different people than we were," says Parsonnet. Pecople have fewer infections, thanks to vaccines and antibiotics, so our immune systems are less active and our body's tssues less inflamed(发炎).
