what is the normal body temperature in fahrenheit

And the body temperature of women born in the 2000s is on average 0.58 degrees Fahrenheit lower than women born in the 1890s. The data showed that the body temperature of men born in the 2000s is about 1.06 degrees Fahrenheit lower than men born in the early 1800s. In the study, Parsonnet and other researchers looked at the temperatures of three groups: data from a study that recorded Civil War veterans' temperatures from the mid-1800s through 1930, more recent data from the 1970s recorded by the Centers for Disease Control, and temperatures of patients visiting Stanford health clinics from 2007 to 2017. 'There's never been a real number because people vary.'īut Parsonnet's research indicates there are still unknowns when it comes to the continued decrease in body temperature. Julie Parsonnet, one of the authors of the study and professor of medicine at Stanford University. 'People are stuck on the 98.6 number, but that number has always been wrong,' said Dr. The findings indicate that Americans' average, normal body temperature has dropped about 0.05 degrees Fahrenheit (0.03 C) per decade, based on their birth year. Research published last week in eLife, shows body temperature has not only dropped since German physician Carl Reinhold August Wunderlich's study in 1851 established the average body temperature as 98.6 degrees, but it has also dropped since the 1970s. But now there's also new evidence that shows we've been cooling off since the 19th century when 98.6 was established as 'normal.' More recently, researchers have known normal body temperature is actually lower than 98.6 and can vary by gender, size, age, time of day and other factors.
