Sweat

Take a whiff of this: Human body odor goes beyond the deodorant aisle. B.O. can reveal what we ate for lunch, whether we’re shy or outgoing, and what kind of spouse we’d make.

We don’t exactly love it when our faces are set ablaze mid-kickboxing class. So we had to ask: What’s up with turning so red?

Sweating buckets during exercise may be a sign of an intense workout, but it may also be a cue to rehydrate and replenish lost electrolytes.

Hate that gross, sticky feeling after a gym session? Don’t — it’s the body’s natural mechanics at work to stay cool and quenched.
