I wish someone had told me this sooner, so I am sharing with MN in the hopes it helps someone else too.
If your bedroom is too hot at night, open the window and place a fan on your windowsill facing outwards. It pulls the air in from behind it, pulling the hot air from the room.
Do this as soon as it’s cooler outside than in to cool the room down before you go to bed.
I was skeptical but it works really well.
Thank me later!! 😉
