How to Cool a Humid Room

Humidity increases during the spring and summer months, which can create a sauna-effect in high rise condos, apartments or rooms on the second floor. Even some first-floor rooms can become over-heated. Cooling down a humid room can make the atmosphere more comfortable. It might take time and some patience until the air feels right again. Certain tools can help assist you with this process and keep the room at a consistent moisture level that is acceptable for you.

You can cool any room, regardless of size.

Turn on your dry dehumidifier for 30 minutes or longer to soak up the moisture in the air.

Open the windows half way for one hour as long as it's not humid outside. A room can become humid even when the air outside is not.

Close the window almost all the way. Leave it open about 1 inch to continue to allow air to flow into the room.

Place a towel at the bottom of the crack in the bathroom door so that no humidity enters the room when someone is taking a shower. This step is only needed when there is a bathroom in the room or close by.

Remove heavy blankets, pillows and plush toys along with plants, fish-tanks or anything that could add to the moisture in the room. Adorn your bed with light-weight cotton sheets.

Things You Will Need

  • Dry dehumidifier
  • Towels


  • Turn on an exhaust fan if the room has one. These fans are usually located in kitchens and bathrooms, but sometimes you can find them in a bedroom. Turn the fan to soak up excess humidity.
  • Make sure your carpet is totally dry because a wet carpet can create moisture in a room.
