Before an Extreme Heat Event
Being prepared for extreme heat events means you have a plan and the supplies to stay cool, hydrated and informed.
- Build an emergency kit.
- Make a household emergency plan.
- Download the Alberta Emergency Alert app for critical, life-saving alerts;
- Get the latest weather advisories from Environment Canada; download the WeatherCAN app from the Apple Store or Google Play Store.
- If you live alone, see if a friend, family member or neighbour can check in with you during an extreme heat event.
- Keep plenty of food, cool drinks and your medication on hand so you can limit going out during extreme heat events.
- Make ice and keep jugs of cool water in your fridge.
- Fill up your vehicle fuel tank in case you need to drive to a cooler place.
- Put up curtains, blinds or awnings on your windows to keep the heat out. You can also cover windows with cardboard.
- If possible, purchase fans and spray bottles to keep yourself cool. Consider installing a window air conditioner in at least one room. Make sure air conditioners and fans are working well.
- If you don’t have an air conditioner, make a list of nearby places with air conditioning, like shopping malls, libraries, swimming pools, community centres and places of worship.
During an Extreme Heat Event
- Stay Hydrated. Drink plenty of water before you feel thirsty and eat hydrating foods such as fruits and fresh vegetables. Avoid sugary, caffeinated and alcoholic drinks as they cause dehydration.
- Stay cool indoors.
- Identify cooler areas in your home, such as a basement, or one room that can be kept cool. Consider using that space to sleep.
- If your home is too warm, consider leaving to stay with friends or family, or looking for public spaces with indoor cooling.
- Prepare meals that don’t need to be heated.
- Take cool showers or baths.
- Schedule outdoor activities carefully.
- Avoid direct sun and rest often in shady areas. Lower your activity level and avoid strenuous activity during high heat.
- Wear light-coloured, loose-fitting clothing that covers the skin, UV-protective sunglasses and a wide-brimmed hat.
- Use sunscreen of SPF 30 or higher.
- Never leave people or pets alone in a vehicle or in direct sunlight.
- Check in on family, friends, and neighbours who are at a higher risk of heat illness or live alone.
