I have the... biggest room.... I keep my room dark. I put blankets over the windows and leave one window open all the time. Sure it gets roasty during the day, but I can handle that.
I cannot sleep if it is hot at night, and my open window creates a bit of a breeze on some nights.
Last night's was awesome. Put me to sleep so fast, the wind did!
Also, I like hearing the noises of the night. I can't sleep in silence, I need noise.
