Is it possible to sweat while swimming?

When you’re working hard and running, biking, jogging, anything of that sort or excercise, you sweat, correct?

I was swimming in gym class one and my face was red and hot when we were finished with class.(12 laps a day ain’t so easy.) I wasn’t sweaty, my cheeks were just hot and I was tired.

So, what if you’re swimming? You’re working hard. Kicking, strocking and figuring out a breathing pattern all under tons of water. So, can you sweat whil underwater?
