How to Cool Down a Room: 16 Effective Tips for Summer Comfort

We've all been there - it's unbelievably hot outside, the sun's relentless, and your home starts to feel more like a sauna than a sanctuary. On such days, keeping even one room cool can be incredibly difficult - but not impossible!

So, if you want to learn how to cool down a room, keep reading! This guide offers some easy, practical tips: both quick fixes you can try today and long-term upgrades that can make a noticeable difference year after year.

Key Takeaways

• Close windows, curtains, and blinds during the hottest part of the day to block out heat: up to 40% of unwanted warmth enters this way. Additionally, hang damp sheets near open windows, place a bowl of ice in front of a fan, or switch to breathable cotton bedding.
• Create cross-breezes by placing oscillating fans near open windows at night. For extra chill, pair them with ice or cold, damp cloths. Set ceiling fans to spin counterclockwise to push cooler air downward.
• Avoid using heat-generating appliances like stoves and dryers during the day. Unplug electronics when not in use. If your region is humid (like Ontario), use a dehumidifier to feel cooler without touching the thermostat.
• If your windows are drafty, cracked, or single-glazed, they may be sabotaging your cooling efforts. Switch to double-glazed windows with Low-E coatings for year-round efficiency. Magic’s ENERGY STAR-certified windows and doors also come with built-in solar shades, thermal blinds, and retractable screens for all-in-one comfort control.

16 Easy Tips That Will Help You Cool Down a Room

It can be difficult to cool down a room while the scorching summer sun is heating your house, but we're here to help! In the following sections, we'll discuss some tips that can provide immediate relief, as well as long-term recommendations that will help you keep your home cool in the future!

As such, here are 16 tips on how to cool down a room fast, even without expensive air conditioning!

1. Close Windows and Curtains During the Day

One of the easiest (yet highly effective!) ways to cool down a room is to keep your windows, curtains, and blinds closed during the sunny hours of the day. Why? Because up to 40% of unwanted heat can infiltrate your room through windows, turning it into a mini greenhouse. Therefore, if you keep your windows closed, they block heat from entering. This can help maintain cooler temperatures indoors.

You can also invest in energy-efficient window treatments that can enhance this effect. They are made of materials that keep the heat out and the cool air in. For example, Magic’s solar shades and thermal blinds, which are integrated into our window systems, can improve a window’s energy efficiency by up to 40%.

The solar shades are made of a semi-transparent material that still allows some light in while covering windows, perfect for days with warm weather. The thermal blinds, on the other hand, are made of an opaque material. They are excellent for hot summer days when you need to block sunlight completely and keep your house cool.

Here's another tip: close doors to unused rooms to avoid doubling your cooling efforts during those hot summer months.

2. Check Your Windows' Insulation

Although keeping your windows closed during a hot summer day is important, it may be ineffective if your windows aren't properly insulated. So, check if:

• The windows form a tight seal when closed.
• There are no cracks around the window, as these are the biggest culprits for cool air leaks.
• The glass is not broken.

If you notice any issues with your windows, it's best to address them right away or replace the windows altogether with energy-efficient units.

These recommendations also stand if you have single-glazed windows. If you live in a region with hot summers, it's of the essence to install double-glazed windows. They consist of two panes of glass separated by an insulating layer of inert gas. Because of this, double-glazed windows serve as a barrier between the outside and the inside of your home. They keep your house cool and even lower energy bills.

All of these details are valid for entry doors and patio glass doors as well.

3. Apply Low-E Coatings

Low-E coatings are designed to keep your house cool in the summer and warm in the winter. They are thin, almost transparent coatings applied directly onto the glass. They help the glass surface control and regulate the absorbed and re-radiated heat.

This means that, during the summer, the low-E coating prevents the window from absorbing the heat from the outside and re-radiating it into your house. They are also incredibly useful during the winter because they will reflect the heat back inside, preventing it from escaping through the window.

Low-E coatings can be applied to existing glass. But if you have poorly insulated or old windows, it's probably best to replace them altogether for long-term benefits.

4. Open Windows at Night

When the sun sets and the temperature drops, it’s time to take advantage of the cooler night air, so open your windows to let the refreshing breeze flow through your home! This not only helps cool down a room but also refreshes the indoor air, making it easier to get a good night’s sleep.

To maximize the cooling effect, create a cross breeze by opening windows on opposite sides of the room. This encourages air circulation, prevents hot air buildup, and ensures a continuous flow of cooler air. You can read more about opening windows at night and turning off the air conditioning in our comprehensive guide on the topic.

Now you're probably wondering, What about the bugs? Well, Magic's got the perfect solution for this as well! Our fully retractable bug screens are perfect for cool summer nights when you want to leave your windows open. All you have to do is pull them out of their cartridge, and they will fully cover your windows, leaving no gaps behind! During the day, you can keep them hidden in the cartridge to enjoy expansive views!

5. Monitor Outdoor Humidity Levels

Speaking of opening windows at night - it's best to avoid doing this when outdoor humidity levels are high (yes, even if the temperatures are low). Research shows that if homeowners turn off AC during the night and open their windows when humidity levels are high, the air conditioner works 21% harder the next day.

Given that the average relative humidity in Ontario is 72.42% during the summer, opening your windows at night may not always be the best idea to cool down a room. You may feel the breeze during the night, but you'll feel much hotter the next day because of moisture buildup.

6. Use a Dehumidifier

If you live in a region like Ontario which has high humidity even during the summer, a dehumidifier is a must! When indoor humidity levels are high, you'll feel much hotter, and the air will feel more stuffy.

Therefore, it's best to keep humidity levels between 40% and 50%. This not only helps cool down a room but also prevents mold growth, which is undoubtedly a concern in humid environments.

7. Buy Indoor Plants that Help Cool the Air

Some houseplants can naturally cool a room. They release moisture through transpiration and purify the air, which improves overall comfort. Try positioning them near windows; this way, they also provide a bit of natural shading and even serve as home decor elements!

Among the best cooling plants are Areca Palm, Aloe Vera, Ficus, Snake Plant, and Boston Fern.

Naturally, these plants won't cool down a room quickly enough for you to really feel the difference, but they can help alongside other measures.

8. Use Fans Strategically

Floor fans and box fans can be your best allies in the battle against summer heat, but using them strategically can make all the difference! It's best to position an oscillating fan across from an open window to create a cross-breeze and cool down the hot room more quickly.

For a more powerful cooling effect, place a large bowl of ice cubes in front of the fan. As the fan blows over the ice, it will circulate cold air around the room, making it feel significantly cooler. Alternatively, you can hang a cold, wet sheet in front of the fan to create a refreshing cooling effect.

And don’t forget about ceiling fans! Make sure they rotate counter-clockwise during the summer to circulate cooler air downwards (make them rotate clockwise in winter to pull cool air up). This wind-chill effect won’t completely remove hot air from the room but will make you feel cooler, helping you stay comfortable even on the hottest days.

In fact, did you know that ceiling fans are actually more effective and energy-efficient than air conditioners? According to the Natural Resources Defense Council, they can make a room feel 10 degrees cooler than an air conditioner. Plus, ceiling fans use just 10% of the energy of an air conditioner.

9. Install Reflective Window Film

Installing reflective window film is another effective way to keep your room cooler. These films significantly reduce solar heat gain, preventing the sun’s rays from heating your indoor spaces. They’re also great for reducing glare, which can make it easier to see your screens and read during the day. Plus, they improve daytime privacy by preventing outsiders from peeking in.

You can get a reflective window film kit that includes all the necessary tools for a DIY application.

10. Switch to Energy-Efficient Lighting

Switch to energy-efficient lighting, such as LED bulbs, as they produce far less heat. This can make a considerable difference in your room’s temperature.

Traditional incandescent bulbs emit 90% heat and only 10% light, which means they can significantly contribute to the heat load in your room. This simple switch not only reduces heat output but also saves energy, so it's a win-win situation.

11. Use Exhaust Fans

Exhaust fans and extractor fans are particularly effective in removing unwanted heat, steam, and odors from the air. They’re especially useful in kitchens and bathrooms, where heat and humidity tend to build up the most.

You can leave all doors open to facilitate airflow and maximize the exhaust fan's effectiveness. This way, the cool air flows more easily throughout your home, preventing hot spots and making your cooling efforts more efficient.

12. Avoid Heat-Producing Appliances

Try to avoid heat-generating appliances like stoves, ovens, and dryers during the day. They can significantly raise the indoor temperature. It's best to use these appliances during the cooler parts of the day, such as early morning or late evening.

For example, you can switch to no-cook meals, such as salads and cold dishes when the hot sun is at its peak. The good news is that these meals are also refreshing, easy to prepare, and highly nutritious!

And don't forget to unplug devices that you're not using. Electrical devices and small appliances can generate heat and consume energy even when turned off, so unplugging them can help maintain a cooler room temperature. Plus, you can also save on energy costs.

13. Cool Down Your Bed

Getting a good night’s sleep can be challenging in hot weather, so why not try cooling down the bed? After all, beds can trap body heat easily, and this will make you feel even hotter.

First things first - switch to cotton sheets or other breathable fabrics. Another trick is to dampen your sheets slightly before sleeping. As the moisture evaporates, it will cool you down, helping you stay comfortable throughout the night. For an extra cooling boost, you can also put your bedding into the freezer for a few minutes before going to bed.

You can also try sleeping closer to the ground. The air is usually cooler near the ground. If you have a couch in the basement, use it during the summer.

And don't forget to take a warm bath or a cold shower before bed! In fact, warm water is actually more efficient when it's very hot because it can help regulate body temperature more effectively by dilating the blood vessels in your extremities.

14. Place Damp Sheets Near Windows

Hanging a damp cloth in front of an open window or draping a wet sheet over a curtain rail allows warm air to pass through it, creating a cooler breeze as it enters the room.

However, keep in mind that you'll have to change the cloth/sheet frequently, as it will dry out quickly.

15. Insulate the Attic and Roof

If your attic is poorly insulated, it will trap heat and then radiate it downwards into your living space. Therefore, it's important to upgrade attic insulation. While this is undoubtedly a long-term solution, it's worth considering if you want to avoid the discomfort associated with high indoor temperatures in the future.

You can also install reflective roof coatings or "cool roofs," as they reflect more sunlight and absorb less heat.

16. Drink Something Hot

Sounds a bit counterintuitive, but hot drinks can really cool you down, even if your room stays hot! Why? Because it increases the amount of sweat your body produces, which can help regulate body temperature.

But the key is sweat evaporation! For you to feel cooler, the sweat your body produces needs to evaporate. If humidity levels are high, or you're wearing a lot of clothing, sweat won't evaporate from the skin's surface, and you won't feel cooler.

Speaking of hot water, don't forget that hot water bottles can also be filled with cold water, which will stay cool for longer!
