With the climate crisis worsening, it's important to find natural ways to keep our homes cool in the summer heat. Air conditioners require a lot of electricity to function, and they use hydrofluorocarbons (HFCs) to cool the air, which are super greenhouse gases that trap 3,000 times more heat in the atmosphere than CO2. So, what are some ways to cool a room without electricity?

What You'll Learn
Use battery-powered fans to circulate cool air
Fans are a great way to cool a room without electricity. They create a wind-chill effect that makes you feel more comfortable. Battery-powered fans are an excellent option to circulate cool air when there is no power. They are compact, portable, and can be placed on a table or mounted on a wall.
Battery-powered fans are an effective way to stay cool when the power goes out. They are designed to be energy-efficient, and some models carry an Energy Star label, ensuring they are gentle on the environment and your wallet. Battery-powered fans can be placed on a table, providing a direct breeze to the user, or mounted on a wall to maximize airflow throughout the room. They are also easily adjustable, allowing you to direct the airflow as needed.
When choosing a battery-powered fan, consider the CFM (cubic feet per minute) rating, which indicates how much air the fan can move. A higher CFM rating is suitable for larger rooms. Additionally, look for fans with larger blades, as they move more air at lower velocities, creating a more comfortable environment without disturbing loose objects. If noise is a concern, check the noise ratings and, if possible, test the fan before purchasing.
The Vornado 630 Medium Air Circulator is a highly recommended battery-powered fan. It is compact, measuring just 12 inches in diameter, and can fill most rooms with a powerful cooling breeze. The Vornado 630 offers high and low settings, with wind speeds of up to 12 mph and 8 mph, respectively. One of its standout features is its ability to create a spiraling helix of air, ensuring a continuous breeze throughout the room. With its sturdy metal construction, attractive retro design, and quiet operation, the Vornado 630 is an excellent choice for circulating cool air during power outages.

Keep windows closed during the day and open at night
Keeping windows closed during the day and open at night is a well-known strategy for keeping a room cool without electricity. This strategy is particularly effective in maintaining a comfortable temperature in your home during hot weather.
During the day, closing your windows helps to block out the sun's heat and prevents warm air from entering your home. This is especially important if your windows are south-facing and exposed to direct sunlight. By keeping the windows shut, you can minimize the amount of heat that builds up inside your home. This approach is supported by the concept of shading, which involves using physical barriers such as sunshades, trees, vines, or window quilts to block direct sunlight from entering your home.
Additionally, closing your windows during the day can help retain any cool air that you have managed to generate or preserve. This is crucial if you have access to battery-operated fans, which can circulate cool air within your space. By keeping the windows closed, you prevent the escape of this cooled air, maximizing its benefits.
On the other hand, opening your windows at night can take advantage of the cooler outdoor temperatures. By allowing a cross breeze to flow through your home, you can naturally ventilate your space and dispel any accumulated heat from the daytime. This strategy is most effective when the outside temperature is lower than the inside temperature, so timing is crucial.
To further enhance the cooling effect of open windows at night, consider placing a damp sheet over the window to catch the breeze. This simple technique can amplify the cooling sensation and provide additional relief from the day's heat.

Wear loose-fitting, light-coloured clothing
When trying to cool a room without electricity, it is important to consider what you are wearing. Wearing loose-fitting, light-coloured clothing is a great way to keep cool. This is because light-coloured clothing is traditionally thought to reflect solar heat away, keeping you cooler in hot weather. Dark fabrics , on the other hand, absorb more heat. However, scientific studies have shown that the looseness and airflow provided by the clothing play a more critical role in keeping you cool.
Loose clothing is generally better in hot weather as it allows air to circulate freely between your skin and the fabric. This helps to evaporate sweat and reduce body temperature more effectively than fitted clothing. Natural fibres like cotton, linen, and silk also allow better airflow and moisture wicking, keeping you cooler compared to synthetic fibres like polyester, which may trap heat and moisture.
Lightweight clothing is also recommended as it allows the breeze to get through and lets moisture escape. This is especially important if you are outside or exercising in the heat, as it will help to keep your body cool and prevent heat-related illnesses. If you are exercising, wear as little as possible to allow for maximum evaporation of moisture from your skin.
In addition to wearing loose-fitting, light-coloured clothing, there are other ways to cool a room without electricity. You can try placing a damp towel in the shade to lie on, wetting your hair, or putting a wet cloth on your head and neck. Keeping windows open at night and closing them before it gets too hot during the day can also help, as can blocking out light with reflective material or white cloth.

Avoid cooking indoors, opt for cold meals
Cooking indoors is a surefire way to heat up your home, so it's best to avoid it when trying to keep cool without electricity. The heat generated by cooking can linger indoors for hours, so it's best to opt for cold meals or alternative cooking methods. Here are some tips to help you avoid cooking indoors and stay cool:
Opt for Cold Meals
Choose meals that can be eaten cold, such as salads, fruits, and other no-cook dishes. These meals won't generate any extra heat in your home and can help you stay hydrated, especially if they contain ingredients like cucumbers, watermelon, and tomatoes.
Cook During Cooler Times
If you must cook, try to do so during the cooler times of the day, such as in the early morning or late at night. This will help reduce the amount of heat generated during the hottest parts of the day.
Outdoor Cooking
Consider taking your cooking outdoors. If you have access to a barbecue, grill, or outdoor kitchen, you can prepare your meals without heating up your indoor space. Cooking outdoors allows the heat and smoke to dissipate more easily, keeping your indoor spaces cooler.
Alternative Cooking Methods
Explore alternative cooking methods that don't require the use of a stove or oven. For example, a haybox cooker or an Instapot can be used outdoors and generate less heat than traditional cooking methods. Overnight cooking is another option, as it allows you to prepare meals during the cooler nighttime hours.
Insulation and Ventilation
Proper insulation and ventilation can help keep your home cooler. Ensure that your kitchen and stove are well-ventilated to prevent heat buildup. Consider investing in insulation to reduce the amount of heat entering your home. This can include shading through the use of sunshades, green roofs, green walls, trees, or vines planted near your home.

Take a cold shower or bath
Taking a cold shower or bath is a great way to cool down when it's hot. It doesn't have to be for a long time, just enough to help you feel refreshed. Start with a temperature that is bearable and slowly turn it down as you adjust.
Exposing yourself to cold water can be an effective way to beat the heat. You can also try applying a cold, damp cloth to your wrists, neck, or head, as these are pulse points that carry blood close to the surface of the skin. Applying cold water to these areas can help to cool the blood and bring down your body temperature.
If you don't have access to a shower, try dumping a bottle of water over your head, or using a water-misting spray bottle. You can also soak a towel or bandana in cold water and wrap it around your head or body.
Remember to keep hydrated, wear loose-fitting clothing in breathable fabrics, and seek out cooler areas of your home, such as the basement or ground floor, to help you stay cool.
