What causes a person not to sweat? - #61004

I am really concerned about this issue I have been having. Whenever I exercise, it feels like I'm working hard but I barely break a sweat. Like, I can run for miles or do intense workouts and it’s like my body is just refusing to sweat. I read about this lack of sweating exercise thing called anhidrosis, and it freaks me out a bit. What causes a person not to sweat at all? I mean, I’m always hot and uncomfortable but no sweat to cool me down. It’s kinda frustrating, honestly. Sometimes I wonder if there's something wrong with me, or if I’m not pushing myself enough? I have tried all these natural ways to sweat more, but nothing seems to work. I have even changed my workouts, thinking maybe it was just the routine, but still, nothing changes. Why do I always seem to be the odd one out in a group workout when everyone else is dripping and I’m just, well, dry? I just want to feel normal and like I’m actually getting something out of my exercise! Does anyone have tips or info on this lack of sweating exercise thing? Would love to hear what you guys think!
