Excerise and sweating

Ch
For the last 2 weeks or so, when I workout I sweat and get hot fast. Not like I'm overheating but I can run for literally 10 seconds and I start sweating. Anyone else find this happening to them? It's sweaty compared to when you have a fever-sweaty but not totally just really warm. I already made sure I could workout as soon as I found out. I've been doing a longer warmup walk and even with that, I get warm and sweaty fast too.
