The Claim
Coffee intake has no significant effect on tympanic or mean body temperature during an 11-minute QSART measurement window.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Drinking coffee does not change ear or core body temperature during an 11-minute sweat test.
See the scientific wording
Coffee intake does not significantly alter tympanic or mean body temperature during the 11-minute QSART measurement window, suggesting the observed increases in sweating are not secondary to changes in core temperature.
Caffeine blocks specific receptors in the nervous system that normally slow down sweat gland signaling, which allows more nerve signals to reach the sweat glands directly, causing them to activate faster and produce more sweat without changing body temperature.
What the research says
1 studyStudy: Coffee intake may promote sudomotor function activation via the contribution of caffeine
Coffee makes you sweat more, but this study shows it’s not because your body gets hotter — it’s because caffeine directly turns on your sweat glands. So the sweating isn’t just a side effect of warming up.
