  2. Extreme Heat • Is defined as summertime temperatures that are substantially higher than average. • For the city of Toronto, extreme heat alerts are issued when historical data shows the expected daily temperatures have led to increased mortality in the past

  3. What happens to your body? • Between 1979-2003, 8015 people in the USA died of complications from extreme heat! • People die when their bodies aren’t able to properly cool themselves by sweating because it’s too humid outside • The change in body temperature (more than 37°C) causes organ damage • This is known as heat stroke. Symptoms include: high body temperature, red and dry skin, rapid heart rate, headache, dizziness, nausea, loss of consciousness

  4. Who’s more at risk? 1. The young: rely on others to give them water, access to cool environments 2. The elderly: may not sense the temperature change • Overweight people: retain more heat • People who are chronically ill: may be on a medication that makes them heat sensitive 5. Athletes: produce more heat as they exercise

  5. How to protect yourself • Drink fluids • Replace salts and minerals • Where appropriate clothing • Stay indoors (or in the shade)

  6. Extreme Cold • Extreme cold weather warnings are issued in Toronto when the temperature without the wind chill is less than -15°C

  7. What can happen to your body? • Frostbite: Toes, fingers and ears are at greatest risk because your body restricts blood flow to these areas in the cold. Symptoms are pain, burning, swelling and sometimes numbness • Hypothermia: drop in body temperature caused by the body’s inability to warm itself by shivering. Symptoms include: muscular weakness, numbness, slowed heart rate, drowsiness

  8. Who’s more at risk? • The very young, the elderly and those with chronic illnesses for the same reasons as Heat stress • Homeless people: no shelter from the cold

  9. How can you protect yourself? • Dress appropriately for the weather • Stay indoors
