DAE face turn red when experiencing extreme anxiety/stress?

I just finished a job interview today. I was anxious all day waiting for it, and I think I did pretty good. But when I finally came out of it, I realized my face was REALLY hot and flushed and I had a pounding headache that wasn’t there before the interview.

It took me a bit to calm down and the headache went away after I did too. I haven’t had an interview for almost 10 years so it just made me feel really stressed.
