Is it normal my ears get hot and red for no reason?

Yes! I have this, it is an abnormality in blood vessels, they expand too quickly and don't constrict fast enough. Mine is related to rosacea. It can happen when Im stressed, after eating but mostly when I change temperatures quickly like going from outside to a warm room. Its probably harmless but its annoying.

This happens to me when I'm feeling stressed/frustrated :(

If u rub ur hot ear and then rub someone elses ear,u transfer the heat. No joke try it

Hmm... that's interesting. I've heard of that before too. Not sure, but if you ever do find out... let us all know what it is.

I've heard people say that when your ears are red, it means you have to pee. But I don't know... do you have to pee? haha! And of course, it's also said that when they're red, someone is talking about you.

My ears do that - and it's usually just one, too. :))

This happens to me sometimes but I've never known why. I'm guessing it's pretty normal.

My brother's ears do that. I don't know if it's normal or not, but I don't think it's harmful.

My moms ears used to do that.. We never found out why though..

^agreed someone is talking about you :-)

someone is talking about you behind your back...
