The Claim

Coffee intake increases activated sweat gland density and sweat output per gland during cholinergic stimulation in healthy young males.

Source: Coffee intake may promote sudomotor function activation via the contribution of caffeine

How it works
1 study reviewed
In plain English

In healthy young males, drinking coffee increases the number of sweat glands that activate and the amount of sweat each gland produces during cholinergic stimulation.

See the scientific wording

Coffee intake increases activated sweat gland density and sweat output per gland during cholinergic stimulation in healthy young males, indicating that caffeine may enhance both the number of sweat glands activated and their individual secretory capacity.

Why this might work

Caffeine blocks adenosine receptors in the nervous system, which removes a natural brake on nerve signals that trigger sweating. This causes more nerve endings to release acetylcholine, which directly stimulates more sweat glands to turn on and each gland to produce more sweat.

What the research says

  1. Study: Coffee intake may promote sudomotor function activation via the contribution of caffeine

    Drinking coffee made people sweat more and activated more sweat glands when their skin was stimulated with a chemical that triggers sweating, meaning caffeine helps the body sweat better.
