9.Keep the Sun Out
Keep window coverings like curtains and blinds closed to keep warm air out while trapping cool air inside. Certain fabric types and colors keep out more heat than others. Studies also show that medium-colored drapes with white plastic backings can lower heat gains in a room by 33%.
10.Freeze Your Sheets
It may sound strange, but freezing your sheets could help you sleep cooler. Grab a plastic bag that seals and put your bedsheets and pillowcases inside. Then stick the bag in the freezer for a few minutes for relief as you drift off.
