Heat Stroke

Heat stroke is a life-threatening condition. City of Ottawa Paramedics would like to remind you to seek immediate medical attention if you, or someone you know is suffering from heat stroke. Heat stroke occurs when the body cannot cool itself, usually by sweating and the internal (core) temperature of the body becomes too high. Children, seniors, outdoor workers and sports enthusiasts are most susceptible to heat stroke.

Causes:

  • The inability of the body to cool itself after prolonged exposure to extreme heat

Preventing Heat Stroke:

  • Keep cool - take frequent breaks when working or playing outdoors in extreme heat
  • Wear light-coloured clothes and hat - they reflect heat from the sun
  • Avoid strenuous work or sports activities during the intense sunlight hours from 10 a.m. to 3 p.m.
  • Drink plenty of fluids throughout the day such as water, juice or sports drinks (Gatorade™)
  • Do not drink caffeinated drinks or alcoholic beverages - they accelerate the effects of heat stroke

What to look for:

  • Headache
  • Dizziness
  • Disorientation, agitation or confusion
  • Sluggishness or fatigue
  • Seizures
  • Hot dry skin
  • Increased body (inner) temperature
  • Loss of consciousness
  • Rapid heart beat
  • Hallucinations

Treatment:

  • Call 9-1-1 immediately - heat stroke can be deadly
  • Move the person to a cool and dry place
  • Apply cool water to skin and reapply often
  • Fan the wet skin
  • Apply ice to head, neck, armpits and groin areas
