If you're looking to cool your room down without using air conditioning, there are a few things you can do. One is to make sure that all of the windows and doors in your room are properly sealed so that hot air from outside can't get in. Another is to use fans to circulate the air in your room and create a cross breeze. Finally, you can try hanging damp towels or sheets over open windows to help cool the air that comes in. If you have access to a basement or cooler part of your house, opening up some doors can also help bring cooler air into your room.
