How To Cool Down A Room: 15 Easy Methods

Lately, summers have been getting hotter. Without some sort of home cooling mechanism, the scorching temperatures quickly become unbearable — and in some cases, deadly. The human body isn’t designed to withstand high heat for long periods. Without reprieve, high temperatures eventually lead to heat illness and heat stroke. Discomfort, dizziness, profuse sweating, and disorientation are concerning symptoms that occur when the body is unable to cool itself.

And overheating isn’t just a summer occurrence. It’s possible to feel too hot in the dead of winter. Stuffy, ultra-warm interiors and flannel pajamas aren’t everyone’s idea of cozy. I keep my thermostat set to eco-friendly temperatures.

When I feel a bit chilly, I pop on a sweater and slippers. Most people who visit my home know to bring extra layers. I love snuggling in a blanket and wearing big chunky knits. If my heat was ever on full blast, I’d overheat immediately. Instead, the moderate temperatures indoors keep the humidity at a livable level and help save on my heating bill.

So how do you cool down a room? Whether it’s the middle of summer or an unusually warm December, here’s how to cool down a room when it gets too hot.

Traditional Cooling Methods

If you have the means to utilize traditional methods for cooling down a room, check out these ideas for instant relief from the heat.

Install Air Conditioning

One of the most obvious solutions is to install an air conditioning unit. There are a variety of options out there including window units and energy-efficient central air. Do your research before investing in an A/C unit or system. A poorly matched air conditioning system is not energy-efficient and may cause humidity issues in your home.

Obviously, there are downsides to A/C. It’s expensive, and it’s an energy-gobbling appliance. If you’re dead set on bringing air conditioning into your home and your house already includes a furnace and ductwork, opt for a heat pump A/C system and save on your heating and cooling costs. Need something more portable? A rolling unit with a window duct is your best option.

Grab A Fan 

A fan helps to circulate air and while it won’t significantly affect a room’s temperature, it’s a must-have for sweltering hot days.

Open A Window

If temperatures at night are cooler than during the day, it may help to open a window. Opening a window is equally helpful on spring days when the house feels stuffier than usual. Let in the breeze and cool down with the help of fresh air.

Lower Your Thermostat

Cranking up the thermostat is a terrible way to keep your house warm in the winter. It decreases humidity (which causes dryness and increases your chances of catching cold and flu viruses) and can seriously impact your electricity bill. If the moment you catch a chill, you find yourself turning up the heat by several degrees, know that this isn’t the best way to manage your home’s temperature.

Cranking up the heat doesn’t warm your house any faster, it just wastes energy. Eventually, you’ll notice it’s too hot and lower the thermostat again.

Keep it at a constant setting (or invest in a smart thermostat) that’s comfortable but not too high. If you get a bit cold, resist the urge to raise the temperature setting by more than half a degree, and try throwing on a shawl or sweater while the house warms up.

Off-Grid And Nontraditional Cooling Methods

Okay, but what happens if you’re stuck in a heatwave and the power is out? That fancy A/C unit isn’t going to be much help. If you’re suffering through high temperatures without the cooling magic of an air conditioner, here are a few ways to cool down yourself and your room.

Keep The Cool Air In

If your A/C is running efficiently, the worst thing you can do is leave doors and windows open. Leaving them open causes your system to work even harder to cool your home.

Invest In Quality Window Treatments

In the spring and fall, I rarely need to touch the thermostat. Our big windows let in so much sun that the house becomes a sort of greenhouse. I often walk around in shorts when it’s below zero because the sun does such an excellent job of heating our interior space.

In the summer, though, the greenhouse effect creates an uncomfortable environment and causes our A/C to work harder than it should. Investing in blackout curtains helps us keep our home cooler inside — even on days we don’t run the air conditioning.

Swap Out Your Lightbulbs

Replace all the bulbs in your home with energy-efficient LEDs. Incandescent bulbs give off a lot of excess heat that can have an impact on room temperature.

Re-Evaluate Your Sheets

I don’t quite understand folks who adorn their beds with thick flannel sheets in the wintertime. The thought of sleeping on that soft, warm material makes me anxious. I sleep hot. My body radiates heat, and I know I’m not the only one with this affliction.

If you’re a hot sleeper, buy the right sheets. For those on a budget, cotton sheets are highly breathable and lightweight. Bamboo sheets are a luxury option with cooling and antimicrobial properties.

Avoid Using The Oven

Resist the urge to bake, roast, or broil during the summer months. Turning the oven on, even on cold days, really heats things up, so it’s a no-no in the summer. If you want to cook, take it outside to the grill.

Hang Out In The Basement

Sometimes it’s impossible to cool down a space, especially a top floor. If you usually sleep on a second story or in a loft attic, consider taking your pillows to the basement for a more comfortable sleeping environment.

Cool Down Your Body

Whether it’s an ultra-hot summer or you’re warmer than everyone else during a winter gathering, it’s not always possible to cool down an entire room. If you’re stuck and feeling uncomfortably warm, try drinking something with ice or stripping off layers of clothing. Use cold therapy packs from the freezer on your neck to help lower your body temp.

It’s easier to cool down yourself than it is to reduce the temperature of an entire room. When it’s boiling, I like to take quick, super cold showers.

The cold water requires less energy, and I keep them short to avoid unnecessary water consumption (icy cold showers are tough to withstand anyhow).

Open Multiple Windows

Your living room is too hot, so you open up a nearby window. You might not notice much of a difference in temperature, though, unless you open up another window to create a cross breeze. 

Create “Icy Wind”

While a fan helps cool down surroundings by circulating air, it doesn’t actually lower a room’s temperature in any significant way. Place a bowl of ice on a table or surface next to your fan and position the fan so that it blows toward the ice. The freshly blown air will feel nice and chilly.

Plant A Tree

If the sun pours into your home and leaves you sweating, consider planting a tree to provide a bit of shade and block some sun. Do your research to find out which type of tree is most suitable for your property.

This strategy requires a bit of patience, of course, since a tree takes time to grow. For a quicker shade solution, install an awning or pergola to keep the sun from overheating your home.


In humid locales, the moist air can increase your sense of discomfort tenfold. Humidity also reduces your body’s ability to cool itself. Run a dehumidifier to control your home’s humidity in the summer. In the winter, dry homes can benefit from the addition of a humidifier to help cool down.

Whether you plan on adding or removing moisture from the air, keep an eye on the humidity levels in your home by investing in a thermostat with humidity sensors. An ideal level is around 45% humidity.
