In a heat wave

  • Very early in the morning, close your windows and curtains to keep the cool night air inside. Leave them closed all day-long.
  • Use an air conditioner to cool down your home. You can also use a fan. Or you can spend a few hours in an air conditioned place.
  • Take cool showers or baths.
  • Drink a lot. Don't wait until you get thirsty.
  • Wear loose clothing, light colours, made of materials that let the air through.
  • Pay attention to how you feel and act immediately if:
    • you get dizzy or faint,
    • you feel nauseous or throw up,
    • you get headaches,
    • your breathing or heart rate accelerate too much, or
    • you are extremely thirsty.
  • Check often on older neighbours, friends or family, especially those who suffer from a chronic disease, to make sure that they remain cool and hydrated.
  • If you take medication or if you have a chronic health problem, ask your doctor or pharmacist if this situation makes you more vulnerable, and follow their recommendations.
  • Prepare meals that do not have to be cooked.
  • Try not to stay out in the sun. Protect yourself from the sun with a wide-brimmed hat that breathes or an umbrella.
  • Reorganize or plan outdoor activities for the cooler times of the day.
  • Avoid strenuous physical exercise or activity.
  • Never leave people, children or pets that you are looking after in a parked vehicle or in direct sunlight.
