A Jimmy Dore Show episode published October 12, 2026, featured independent medical researcher Matthew Cormier discussing research that reports average human body temperature has fallen from the long-cited 98.6°F to about 97.7–97.9°F.
Cormier argued that the reported change could signal concerns involving immune function and metabolism. He also suggested possible connections with chronic infections, metabolic disorders and environmental exposures, including heavy metals and wireless radiation. The episode description presents these as his claims and areas of discussion; it does not provide evidence establishing that lower body temperature causes those conditions or that the proposed exposures are responsible.
The conversation also addressed fasting, autophagy, the microbiome, temperature regulation and the hypothalamus. Cormier said approaches intended to affect immune or metabolic function may have different effects depending on a person’s health.
The episode description says Cormier called for more research and public attention to the reported temperature decline. It does not identify the studies discussed or provide details about their methods, so the findings and broader health claims cannot be independently assessed from the supplied material.
Other subjects listed in the episode description include comments attributed to actor Mark Ruffalo about Biden administration officials, potential U.S. sanctions related to U.K. opposition to Israeli West Bank settlements, and claims concerning the 2026 midterm elections. Those topics are not substantiated in the supplied material and are not assessed here.
