EXCERPTS: The average temperature of the human body has been steadily declining since the middle of the 19th century, and scientists aren't sure why. A new study suggests one key factor that might play a role in this: gut microbes.
[...] The team studied gut bacteria samples taken from 116 people with sepsis, discovering that there were wide variations in the microbiota – and that the variations correlated with changes in the temperature trajectories of the patients.
[...] While it's not enough to show that gut bacteria are why our insides have been getting cooler over the last 150 years, it's an interesting hypothesis – and it shows how our gut microbiome is linked to body temperature.
"Arguably, our patients have more variation in their microbiota than they do in their own genetics," says internist Kale Bongers, also from the University of Michigan. "Any two patients are more than 99 percent identical in their own genomes, while they may have literally 0 percent overlap in their gut bacteria."
In further tests on healthy mice with and without a bacteria microbiome, lower base body temperatures were observed in the animals without the bacteria – while treatment with antibiotics also reduced body temperature in the mice... (MORE - missing details)
