Heat waves are challenging for just about everyone, but they can be especially uncomfortable (not to mention dangerous) if you don't have air conditioning or limit how frequently you run it.

Many Americans find ourselves in that situation: One in three U.S. households have difficulty paying for energy and utility bills, according to a 2018 report published by the U.S. Energy Information Administration (EIA). As a result, 11 percent of households keep their homes at unhealthy temperatures, per the EIA — including during heat waves.

And the novel coronavirus pandemic has made dealing with summer heat even harder, with many people spending more time at home than ever before. Plus, go-to destinations with chilled temperatures — such as movie theaters, malls and restaurants — are now closed, and if you're in a hard-hit area, you may not want to venture out to your local cooling center to find relief.

Fortunately, there are still smart — and easy — tweaks that can help you stay relatively cool, even in the midst of surging heat. Here, eight ways to cool down your home without an air conditioner.

Get tips on how to stay healthy, safe and sane during the novel coronavirus pandemic.

1. Get the Most Out of Your Fan

You can make your indoor fans cool rooms even more efficiently by placing frozen water bottles or a cooler filled with ice directly in front them, says Shane Dutk, founder and general manager of Review Home Warranties, a website that assesses homeowners' home warranty options. You can also drape a towel dampened with cold water over its frame. These tactics will immediately spread cooled air.

Ceiling fans are particularly key, as they create a wind chill effect. Reverse the motor to move the blades in a counterclockwise rotation to create a breeze effect in the summer, says Mark Dawson, chief operating officer at One Hour Heating and Air Conditioning, which installs, maintains and repairs heating and air conditioning systems.

2. Take Advantage of Night Breezes

When dusk hits, open all the windows and, if you can do so safely, the doors — this will promote air circulation and allow cooler air to enter your home, says Lina Velikova, MD, PhD, medical advisor to MedAlertHelp.

Place box fans close to the doors and windows — they can act as an exhaust system that pushes the heat out of your home. At dawn, close all those windows up again, and also close all your blinds and curtains, to diminish the amount of sun entering your home.

3. Place Plants Strategically

They can block some of the sun and keep rooms cooler throughout the day, Dawson says. Plants actually release excess water into the air from their leaves to cool themselves — and everything around them, too.

What You Eat and Drink Matters, Too

When it’s really hot, you’re at much higher risk to become dehydrated, as excessive sweating is your body’s way of trying to cool down. Follow these tips to keep hydrated:

  • Drink plenty of fluids.
  • Seek out fruits and veggies with high amounts of water (think cucumber, melons, leafy greens, even raw onions!) to help with hydration, says Nikola Djordjevic, MD, medical advisor for HealthCareers.co.
  • Avoid drinking alcoholic beverages and caffeine during a heat wave, Dr. Djordjevic says. Here’s why: They're both diuretics, which means they can dehydrate you and deplete your body of water, as well as other essential nutrients.

4. Cut Unnecessary Heat Sources

Who needs to cook during a heatwave? It makes sense to avoid using appliances like your oven and stove, especially during the day, Dr. Djordjevic says. Instead, grill outdoors, or, if you must cook inside, use slow cookers or Instant Pots, which will prevent your kitchen from turning into a sauna.

Another tip: Replace all incandescent light bulbs with fluorescent light bulbs, which emit less heat, and are the most energy-efficient option out there.

5. Barricade in the Basement

If you've got a finished basement, consider seeking shelter there whenever a heatwave hits. During the summer, hot air rises, and consequently, the upper stories of our homes become hotter. "Ground floors are significantly cooler, and basements oftentimes are at a perfect temperature if you're looking for a little livable oasis," Dr. Djordjevic says.

6. Freeze Your Bedding

Throw your pillows and sheets in the fridge or freezer during the day, then bust them out right before bed, Dr. Djordjevic recommends. (Simply roll them up in any large plastic or paper bags you have around the home.) You can even stay prepared for the week by freezing a couple of sheets in a plastic bag, and removing them when needed.

7. Consider Installing Evaporative Coolers

If you live in an area that tends to have low humidity, you may want to consider evaporative coolers, window units that remove heat from the environment by using water evaporation to create cool air, says Cisco DeVries, an energy expert, former aide to the U.S. Secretary of Energy during the Clinton Administration and CEO of OhmConnect.

These devices cost about half as much to install as central air conditioners and use only about one-fourth of the energy, per the U.S. Department of Energy. And unlike central AC, which just recirculates the same air, evaporative coolers provide a steady stream of fresh air into the house.

8. Add a Whole House Fan

If you live in a multi-story home, you can buy and install a whole house fan for less than $2,000. It's installed in your attic and creates negative pressure by drawing the hot air in your home into the attic, DeVries notes. This negative pressure then draws in cooler air from outside, cooling down your home.

While you're up in the attic, put in some insulation, which will help keep your house warm in the winter and cool in the summer.

Concerned About COVID-19? 

Is This an Emergency?

To reduce the risk of spreading COVID-19 infections, it is best to call your doctor before leaving the house if you are experiencing a high fever, shortness of breath or another, more serious symptom.
