Apple watch during hot yoga?

Has anyone worn their apple watch specifically during hot yoga? I'm planning to begin attending regularly, but I'm not sure whether it will affect the watch. I have a series 5.

If so, any issues with the watch during or after? It's only 30 minute classes, but haven't tried wearing the watch during.... It's annoying bc I am typically rigid with tracking workouts & don't like to just guess the active calories burned / etc. Feel like that kind of defeats the purpose. Thanks!
