No air conditioner? Here's how to keep cool during extreme heat

There are ways to ride out a heat wave in (relative) comfort, even if you don't have air conditioning.

Here are some tips to stay cool during the hottest days of the year without an air conditioner:

  • Close curtains and blinds during the day. This will help keep heat-generating sunlight out of your home. Blackout curtains can be especially effective.

  • A dehumidifier won’t change the temperature of a room, but it can make an environment feel cooler by reducing humidity.

  • Make a DIY cooling system by placing ice or frozen water in front of a fan, but ...

  • ...Use fans wisely. Research shows that fans don't effectively cool people down in extreme heat.

  • Take a cold shower or bath to lower your body temperature.

  • Drink water regularly, even if you're not thirsty. Add electrolytes if you're sweating heavily. Skip caffeine and alcohol, which can be dehydrating.

  • Wear loose-lightly-coloured clothing. Cotton and linen are fabrics that breathe nicely.

  • Stay low (at night). Heat rises, so sleep on the floor if it's comfortable to do so.

  • Refresh with a frozen washcloth or water bottle.

  • Choose cold meals, like salads, fruits, and smoothies, to avoid heating your space during meal preparation.

  • Let in cooler air at night. Open windows at night to allow cooler air in. Use fans to help it circulate.

  • Libraries, malls, community centers, coffee shops, movie theatres, and other public spaces offer air conditioning and shade during the hottest times of the day.

Lastly: If you experience symptoms of heat-related illnesses like dizziness, nausea, or confusion, seek medical attention.
