The Claim
Consumption of 16 fluid ounces of coffee containing 225 mg of caffeine shortens sweat onset time and increases sweat rate during both axon reflex and direct sudomotor activation in healthy young adult males.
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 16 fluid ounces of coffee with 225 mg of caffeine reduces the time it takes to start sweating and increases the amount of sweat produced during heat-induced sweating responses in healthy young adult males.
See the scientific wording
Consumption of 16 fluid ounces of coffee containing 225 mg of caffeine significantly shortens sweat onset time and increases sweat rate during both axon reflex and direct sudomotor activation in healthy young adult males, suggesting caffeine may enhance cholinergic-mediated sweating responses under controlled conditions.
Caffeine blocks adenosine receptors in the nervous system, which removes a natural brake on nerve signals that trigger sweating. This causes more acetylcholine to be released, which directly activates sweat glands and spreads the signal to nearby glands through a local nerve reflex. As a result, sweat starts sooner and more glands produce more sweat.
What the research says
1 studyStudy: Coffee intake may promote sudomotor function activation via the contribution of caffeine
This study found that when people drank a big cup of coffee, they started sweating faster and produced more sweat when their skin was stimulated with a chemical that triggers sweat glands. This means caffeine in coffee helps the body’s sweat system work better.
