It’s no secret that guys sweat (a lot), but any woman knows that we do, too.
To study this sex difference, Japanese researchers compared the sweat responses of women and men during exercise, at different levels of intensity. The more physically trained the subjects were, the more “efficient” their sweat rate (meaning, they started sweating sooner and more easily).
The sex difference? As exercise intensity increased, physically trained men improved their sweat rate much better than trained females. And untrained females needed to work out harder and reach a higher body temp to sweat as much as their male counterparts.
Turns out the old adage is true: Men sweat, women glow.
