Alberta Health Services: Heat Advisory issued for Calgary Zone


CALGARY – Due to elevated temperatures forecast for the Calgary Zone of Alberta Health
Services (AHS), a heat advisory has been issued for the entire Zone.

Effective immediately, residents of and visitors to Calgary Zone are advised to take the following
precautions to protect themselves, their families and their neighbours from the potentially
harmful effects of the sun (including burns, heat-related exhaustion and heat stroke):

  • Consider rescheduling outdoor activities to cooler hours of the day.
  • Take frequent breaks from heat, spending time indoors at cooled public buildings (including
    malls or indoor pools).
  • Drink plenty of water and other non-alcoholic, non-caffeinated beverages to stay hydrated.
  • Do not leave any person or pet inside a closed vehicle.
  • Apply a sunscreen of at least sun protection factor (SPF) 30, at least 20 minutes before
    heading outdoors. Be sure the SPF 30 screens out both UVA and UVB rays, and reapply
    frequently (as directed on product label).
  • Wear a wide-brimmed hat and sunglasses (with a UVA/UVB CSA certified seal).
  • Wear light-coloured long-sleeved shirts and pants that cover skin.

Residents and visitors should also monitor for symptoms of heat stroke, including high body
temperature, lack of sweat, disorientation, fainting, and unconsciousness.

“Normal activity that may be safe on a cool day might be dangerous in current weather
conditions. If you start to feel overheated, stop your activity immediately, seek shade and drink
fluids,” advises Dr. Brent Friesen, Medical Officer of Health, Calgary Zone. “Seek medical
attention immediately for any individual feeling faint. While awaiting medical attention, move the
individual to a shaded area, and remove his or her outer clothing and shoes. You should also
wrap the person in a wet towel until medical care is being provided.”

Particular vigilance is urged for vulnerable individuals, including children, seniors, individuals
with pre-existing respiratory or cardiovascular conditions, outdoor workers, as well as those who
are socially isolated.

“Excessive heat can aggravate underlying medical illness such as congestive heart failure, and
can also be of heightened danger to children and seniors. Individuals who are socially isolated
may not know when or how to seek help, or be able to monitor their own symptoms.”
“We not only need to pay attention to our own bodies; we also need to look-out for our
neighbours and loved ones,” says Dr. Friesen.

As temperatures are forecast to remain elevated for the next 72 hours, this heat advisory will
remain in effect for the next 72 hours until noon on June 29, 2015.
