Why do we sweat when we're scared?

Surely you'd want to *not* smell strongly when a predator is trying to find you.

The sweat that is excreted by humans due to the fear response contains certain hormones and pheromones that, when inhales, heighten another person's alertness. Basically, what we sweat out of fear is to help other people in our situation escape whatever it is is causing us fear.

Stress sweat is meant to help our species survive by increasing our awareness of a given situation. The glands that produce stress sweat are different from the glands that produce normal heat-related sweat, and only activate in response to the "fight or flight" response.
