Could my hot flashes, which have nothing to do with menopause, be stress related?

I started a new job a couple weeks ago. I love it but there is a lot to learn, and I am trying very hard to make sure I do everything well. Today, while I was working at my desk, I noticed I suddenly felt like I was burning up. Many of my coworkers were wearing sweaters, so I don't think it was hot in the room. When I walked outside after work, my skin felt really hot against the cold air. Later, when I was at home, I began thinking about some things I need to take care of tomorrow and I got another bit of a hot flash. I am in my 20s, so its not menopause related. Have you ever had stress related hot flashes? Is that normal?
