Q: Why do some people sweat so much more than others while doing the same activity?
Oz Says: If you're the one in spinning class with the puddle under her bike, congrats! It could mean you're more fit than that dry lady on your left. Sweat is how your body cools down when its core temperature rises.
"Over time, a fit person's body becomes better at regulating her core temperature, so she starts to sweat earlier and harder than someone who's less fit," says Lindsay Baker, PhD, principal scientist at the Gatorade Sports Science Institute in Barrington, IL.
Another notable sweat-rate factor: body size. Bigger people often perspire more than smaller folks do because larger bodies generate more heat when they move. That's why guys tend to shvitz more than women — they're typically larger.
