A recent study found a connection between the gut microbiome and body temperature. The study used data from patients with sepsis and found that the mix of bacteria in the gut can have a big impact on how a person’s temperature fluctuates. They also used mouse models to confirm their findings, which showed that mice without a gut microbiome had lower body temperatures than normal mice. This study highlights the gut microbiome’s role in regulating body temperature. The researchers even think that changes in the gut microbiome over the past 150 years could explain why the average human body temperature has decreased. So, the next time you take your temperature, remember the tiny microorganisms living in your gut play a big role in keeping our body temperature in check.
