Why do I get a warm face and warm ears after a long period of gaming?

Gambling in the sense of ps4. Sometime after an hour or two I get a warm head or a warm face and red, warm ears, is that normal?

I don't know, but it only happens to me in one ear.

I think that's relatively normal xD
I often get that while gambling. Is due to the room temperature i guess

Or the effort?

Also happens to me sometimes: /
