Sweating?

Anyone else’s baby ever just excessively sweat at random times? My baby boy sweats in his sleep which I read is normal, but he also is drenched in sweat when he’s eating, playing, and crying. And I mean drenched. Hair drenched, and sweat drops all over his nose and forehead. I never thought much of it during summer bc it was hot inside my house and out, but now that it’s becoming cooler and I still have him in light clothing (literally just a short sleeve onesie) and he’s still being drenched in sweat, I’m scared there might be a bigger issue. He does not have a fever.
