“Normal” temperatures are not so hot

    When you visit the doctor, the doctor usually checks to see    1   your temperature is “normal”. Now, new research suggests that the “normal” temperature of humans has been dropping over the last 200 years.

    Human beings    2    warm-blooded animals. So our bodies need to work hard to stay at the same temperature. Our bodies make heat from the food we eat.We also have other ways to     3    our temperatures constant (恒定的). For example, we will sweat when we’re hot or get goose bumps (鸡皮疙瘩) when we’re cold.

    Though human temperatures can all be a little    4    , most doctors consider 37℃ to be normal. That’s been true since 1851, when a German doctor called Carl Reinhold August Wunderlich studied 25,000 patients. His results showed an average human body temperature of 37℃.

    But over time, other scientists studying body temperatures have gotten results with lower average temperatures.

    For example, a 1992 study found an average temperature of 36.8℃. In 2017, scientists looked at the temperatures of 35,000 patients in Britain and found their temperatures were 36.6℃ on average. Many people believed that the differences were because   5    mistakes in the earlier measurements.

    Now a new group of researchers says, on average, human body temperature   6    to have been dropping 0.03℃ every 10 years. The obvious question is “Why?”. One of the researchers says clearly, “We don’t know.”

Still, the scientists do have a few possible explanations.

    One explanation could be simply that humans have become    7    over time. Science and medicines have gotten better, and doctors have found many ways to improve the health of their patients.

    The scientists also say it’s possible    8  things like heating and air-conditioning help make it.With them, humans don’t have to work so hard to control their body heat, and can run at a lower temperature.

    It’s important to remember that this story is about averages.In the real world, different people   9    different temperatures.

    But no matter what your temperature is today, it probably would’ve been higher if you had lived 200 years ago and that’s     10     cool!
