eli5: If hot air rises and cool air falls, why are we told to have our ceiling fans blow up in the winter and down in the summer? Wouldn’t it make more sense to pull the air in the opposite direction it naturally goes to help it circulate?

Fans don’t cool by moving cool air down to you. They cool by moving air across you body. The difference in air temp between you and the fan is going to be pretty small.
