Staying Healthy in the Heat

Southern Alberta summers can produce periods of extreme heat and dry conditions. It is important to familiarize yourself with the signs and symptoms of heat-related illnesses, especially if you are working or spending time outdoors.

Possible Signs and Symptoms of Heat Exhaustion

  • Cool, pale, clammy skin
  • Heavy sweating
  • Headache
  • Dizziness or fainting
  • Weakness or exhaustion
  • Muscle cramps
  • Nausea
  • Rapid breathing and increased heart rate
  • Extreme thirst

If you experience any of these symptoms during extreme heat, immediately move to a cool place, rest, and drink water. If symptoms worsen or do not improve, seek medical attention.

Possible Signs and Symptoms of Heat Stroke

  • Hot, flushed skin
  • High body temperature
  • Severe headache
  • Altered behaviour (e.g., confusion, lack of coordination, aggression, increased irritability)
  • Rapid, shallow breathing
  • Rapid, irregular, weak pulse
  • Dizziness or fainting
  • Loss of consciousness or unresponsiveness
  • Seizures

Heat stroke is a medical emergency! Call 911 immediately and then contact Security Services at (403) 329-2345.

While waiting for help, others should attempt to cool the affected person right away by:

  • Moving them to a cool place (if possible and safe to do so)
  • Applying cold water to large areas of the skin
  • Fanning the person as much as possible

Safety Tips

  • Check the weather forecast ahead of time to help plan work for cooler days or times of day.
  • Conduct or revise your hazard assessment to identify heat hazards and implement appropriate controls. Controls could include cool rest areas, water stations, or planned breaks.
  • Clothing choices can be important. Consider wearing a hat and choosing clothing that is loose-fitting, lightweight, breathable, and light-coloured.
  • Drink water regularly throughout the day and stay hydrated.
  • Take frequent breaks in a cool or shaded area, especially during periods of prolonged outdoor work or physical activity.
  • Know the signs of heat-related illnesses and pay attention to how you and those around you are feeling.
