For the past few years, I’ve been on a bit of a tirade about our family’s digital thermometers. My kids think they’re toys, and I often catch them shoving one up their nose or trying to heat it up by the radiator, hoping to convince me to let them skip school. But it’s not just their antics; I’ve genuinely started to suspect that these thermometers are faulty. “There’s no way I’m only 97.3 degrees,” I grumble, shaking my head at the gadget. “This thing is broken… again.” “They just don’t make ’em like they used to,” I lament.
Well, it turns out I might be the one who needs a reality check because that 97.3 degrees might actually be my normal temperature, based on recent research. Yes, you read that right. The long-standing belief that 98.6 degrees Fahrenheit represents the average human temperature is being challenged. Researchers at Stanford University found that our average body temperature has dropped over the last 200 years, with the new average hovering around 97.5 degrees.
Dr. Jamie Anderson, one of the study’s co-authors, noted in a press release, “The notion that our normal temperature is 98.6 is outdated.” The study, published in eLife, examined human body temperature data dating back to the 1800s, when the figure was popularized by German physician Carl Reinhold August Wunderlich. His 1868 publication cemented the number, but it seems recent findings are calling it into question.
By analyzing data from various sources—ranging from medical records of Civil War veterans to contemporary health surveys—the researchers determined that body temperature has decreased by approximately 0.03 degrees every decade for the last 157 years. Fascinating, right?
What’s Causing This Temperature Drop?
So, what’s causing this temperature drop? The researchers have some ideas. One theory suggests that our modern environment, which is more temperature-controlled, has altered our physiology over time. “We’re not the same as we were in the past,” Dr. Anderson explained. “Our living conditions, the microorganisms we encounter, and our dietary options have evolved.”
Another theory points to improvements in public health and lifestyle. Dr. Lisa Wong, a family physician, adds that as we’ve adopted healthier lifestyles, our bodies may not need to work as hard to regulate temperature. “With less inflammation in the body, we’re seeing lower average temperatures,” she mentioned.
How Does This Affect Our Understanding of Fevers?
This begs the question: how does this affect our understanding of fevers? Traditionally, 100.4 degrees Fahrenheit has been the benchmark for fever. Dr. Wong reassures us that for now, we should stick with this standard. “While the average may have shifted slightly, it doesn’t change the practical thresholds we use for fevers,” she stated.
Ultimately, it’s beneficial for parents to know their child’s baseline body temperature. If you have any concerns regarding temperature norms for your little ones, it’s wise to consult with your healthcare provider.
In the end, perhaps those of us who have been complaining about our malfunctioning thermometers should take a step back. A reading in the 97-degree range might just be perfectly normal. Cheers to cooler and possibly healthier bodies!

In summary, recent research indicates that the average human body temperature has declined, and the long-held 98.6-degree standard is no longer accurate. This shift can be attributed to changes in our environment and improvements in health. As such, understanding individual baselines is essential, especially for parents monitoring their children’s health.
