Im getting heat rash in winter?

I wasn't very warm today I touched my back and it was VERY HOT. I ended up not being able to sleep early in the morning. I didn't know what it is but when I eat certain things and drink back tea and move around it gets better. If I don't eat it gets worse. I was not bundled up and it is cold it just happens randomly.
