My friend doesn't sweat much and the heat effects her more than it would a regular person. This was the first time me and my friends had gone on a hike without adults with us so we were really scared and didn't know what do to. The person who called 911 thought it would be a good idea just to be safe. We probably would have been able to cool her down after a while, but at the time taking her to the hospital seemed like the right thing to do.
