Things You'll Need
Dark, heavy curtains
Keeping cool during the warmer months can be a challenge, especially without the aid of an air conditioner. An air conditioner lowers the temperature in a room by pumping it full of cold air. There are other ways to reduce room temperature, though. While these methods may not be as effective as using an air conditioner, they are helpful nonetheless. Some methods of cooling down a room are preventative steps that keep it from heating up in the first place, while others treat the hot air and lower an already-high temperature.
Close the windows during the day and block out the sun with dark, heavy curtains.

Open your windows at night after the sun has gone down. The cooler air filters into your room. Close the windows before the sun rises to trap the cool air and keep out hot air.
Abstain from using your oven or stove top during the day. These generate unnecessary heat, and appliances such as dishwashers introduce moist heat to the room. This humidity makes the air seem hotter and more stifling.
Use a dehumidifier to reduce humidity in your room.
Place portable fans throughout the room to circulate air and create a mild breeze. Sit in front of a fan, then spray water into it with a spray bottle for a refreshing, cool mist.
Do not leave your refrigerator door open to cool down a room. It not only wastes energy, but it actually increases the temperature of the room.
