ELI5: Where did the tradition of having bedrooms on the second floor come from?

I know that any small room can be a bedroom but i want to know why their always upstairs in a house with more then 1 floor.

Did it come from the idea of "Staterooms" in old mansions?

Bedrooms have been upstairs since houses had two stories, because it puts them away from the public spaces, away from the livestock, and away from some of the creatures that crawl around on the ground. Also it's warmer in the winter, and catches more breezes in the summer.
