Baby sweats when sleeping

Hey mommas! I need so advice...

My babe wakes up every sleep drenched in sweat. At first I thought it was because he was wearing thick pjs for the winter. So we switched to light ones. When he kept doing it I put just a shirt and diaper- which he is still sweating through. We swaddle him most nights and naps. Could this be why? Or does he just run hot? I'm not sure if this is something that I should be concerned about or not!

Tia!
