Why do we sweat when we get really scared? It doesn’t seem to have an advantage to me. Also, cold sweat really smells. If your enemy can smell that you’re scared shitless, doesn’t help with surviving, right?

“The evolutionary theory behind why stress sweat smells so bad is that it’s believed the odor triggers an alert response in our brains,” Hafeez said in an email to CNET. “When humans smell this type of perspiration, we can tell it’s the physical response to a mental concern, like fear or anxiety.”
“This stench alerts the people in the area that there is something scary happening here that we would not like to be a part of,” she says.
