Well, you adjust. We don't use AC even in the summer and so we have adjusted to the heat. It's the change to colder that really gets to me. Plus, I leave the fan on at night because I've gotten used to the white noise and the air movement, that makes it seem colder. My bedroom has a wall of wooden doors that I leave open to a private terrace which has only mosquito screen for a roof, it's like I'm outside. I don't know, I get cold at night even in the summer.
