How To Cool A Room Without Air Conditioning?

These days, we’re not only concerned about energy costs but about consumption. If you’re looking to beat the heat without turning on the AC, or if your dwelling doesn’t have an air conditioner, these tips may help you stay a bit cooler during the sweltering summer months.

Turn off sources of heat. Incandescent bulbs, the stove, your computer, the coffeemaker and other small appliances release heat into your home. Who wants to cook when it’s 90 degrees out anyway? Have a salad and some iced tea instead. Better yet, break out the popsicles and ice cream.

Invest in blackout curtains/blinds. Some versions of blackout curtains are even made with thermal insulation, which would make them useful in both summer and winter. In the summer, however, they’re especially useful to keep a room dark and cool.

Use fans. Although fans do not actually cool a room (the electricity driving the fan turns into heat) they create a wind chill effect. By blowing the air around, the fan helps you evaporate the sweat from your skin, which is how you disperse body heat. The great the rate of evaporation, the cooler you will feel.

Closely watch the temperatures both indoors and out. When it is cooler outside, open the windows. If possible, it’s good to open windows on either side of the room for cross-ventilation. If you have operable skylights, open those up to let out the hottest air. Shut the windows when it heats up outside to contain the cool air inside your home.

Add some ice in front of your fans. You can create a mini air conditioning effect by pairing your fans with a container of ice. A gallon jug filled 3/4 full of water and frozen over night will work nicely for this purpose – just put it on a tray or in a bowl to catch the condensation. Set your fan behind the ice – as the air blows over the ice and onto you, it should get cooler.

Use the “fan only” setting on your heating system to keep the air moving. If your home does not have an AC unit, you may not think of looking at the thermostat during the summer. But there should be a switch for the fan – usually it will say “auto” or “on.” Move the switch the the “on” position. This will add air circulation.

Install heat-reflecting film on windows that get a lot of sun exposure. Not only will this keep your house cooler, it will also block the UV rays from fading your fabrics, furnishings and artwork. Window film is available at your local home improvement store. It’s very inexpensive.

Reduce indoor humidity Humidity makes air feel warmer, so if possible minimize cooking, showering and washing clothes during the hottest part of the day.

Stay downstairs. The rooms on the lower level of your house are likely to be cooler. If you have to go upstairs to go to bed, take a cold shower before you turn in for the night. For even more relief from the heat at night, store your pillowcase and fitted sheet in the freezer during the day and put them on the bed right before you climb in – it will be a temporary but welcome respite from the heat.

  1. Terrible ideas. A lukewarm shower is better as cold showers make you hotter. Also, a fan blows so best to have it blowing out the window if ti is hotter inside.

      1. Suck, cold showers do not necessarily make you hotter. It depends on how hot and humid the room is at the time you take a shower. All showers work to to bring the body’s homeostasis into alignment with the air temperature surrounding the person. A person will dry off faster in a hot and dry climate than (s)he will in a hot and humid climate. How fast and what method of drying you use after a shower determines how cool you get or stay. It’s not the temperature of the water that makes the most difference.

    1. Jimbo, I’ve heard of lukewarm or warm drinks being better for cooling a person off than a cold drink, but I have never heard of a cold shower that makes a person hotter. It may be better to take a lukewarm shower instead of a cold shower though, simply so you don’t put your temperature regulator into shock by dropping your core temperature down too quickly. Most people can’t stand more than a 3-5 degree change in their core temperature without suffering either hypothermia or hyperthermia.

  2. On extremely hot days, I fill the bathtub up with luke-warm to cool water and soak in the tub on and off throughout the day.  If I don’t have time for a full soak, I just soak my feet in the water for awhile.

    Rinsing your hands and feet in cool water frequently throughout the day/night will also keep you cooler.  I also use an ice pack or cool, damp wash cloth on my forehead or the back of my neck to help me cool down.

  3. You can fill a large ziplock bag with water, stick in the freezer, and there you have your block of ice. If you freeze several bags you can use them in succession and re freeze them as you go.

  4. I use a fan with an ice pack behind, in the front room, and bedroom. If you have a window in the back of your place, put a fan facing outward. It gives you cross ventilation. I won’t say it keeps you super cool, but if you keep up on the ice packs, it is tolerable. I’m working on another idea that I can use in multiple rooms. I saw an idea on YouTube. It’s worth a look.
