Heatwave warning: What you need to know about heat-related emergencies

By Shaylyn MacAulay
 
Summer is in full swing in many parts of Canada and folks are enjoying more time outside whether at the lake, lounging poolside or tending to that lawn that needs mowing. With a renewed appreciation for the outdoors after having spent months cooped up, many of us are happy to simply head out the front door and enjoy the sunshine on our faces. While we may be tempted to simply throw on our sandals and rush outside to soak up the sun, there are some important heat-related safety tips to keep in mind.
 
Heat-related emergencies such as heat cramps, heat exhaustion, or heat stroke, can happen to anyone who stays in the summer heat and sun for too long.

Prevention really is the best medicine! The best way to deal with a heat-related emergency is to avoid one altogether.
  • Drink plenty of cool fluids before and during your time outside
  • Apply sunscreen with SPF 15 or higher as a sunburn will reduce your body’s ability to cool itself
  • Stock your backpack with the essentials like sunscreen, sunglasses and plenty of water to keep you hydrated
  • Wear a hat - a perfect excuse to get yourself a new accessory!
  • Avoid being outside during the hottest part of the day
  • Check your local humidex as the humidity will make a hot day feel even hotter
  • Take lots of hydration breaks and cool off in the shade - don’t forget to reapply sunscreen while you’re at it!
  • Adjust your activity and avoid playing or working for too long in the heat
