You seriously need to acclimate yourself to higher sleeping temperatures in summer, it can be done.

Before I finally got a window unit for my room, I was regularly sweating, in just underwear, with no covers. And remember, I’m a night person working night shift so heat was that much worse because I have to sleep during the daytime hours. It was fucking awful, and I have a lot of choice words to say to you if you decide to be judgemental about it.
