Do you have a visitor coming? Is it winter? Does your guest know your apartment/house is actually a sauna/kept at 88 degrees? Why not let her in on that? Because maybe she won't pack that long sleeved T-shirt and flannel pajama pants, which, when she wears them at night, will cause her to perspire so much that when she wakes, she will be 70% smaller and shriveled-looking for lack of water. Inform your guests that they will be sleeping in what amounts to a tropical greenhouse! It's the polite thing to do.
