Hot leftovers straight into the fridge?

I was taught to let leftovers cool to room temperature before putting them in the refrigerator or freezer, but it has occurred to me that I have no idea why. Is it for food safety reasons? Is it to help the tupperware last longer? Is it to save on refrigerator electricity bills (this seems the most plausible, but how much of a difference would it actually make?)? Is it something else entirely? Or is it just one of those entirely baseless pieces of "wisdom" that gets passed down forever?
