IMPORTANT MESSAGE FROM THE MEDICAL OFFICER OF HEALTH

Re: Heat Warning in Effect

A Heat Warning has been issued for the following regions:

  • United Counties of Stormont, Dundas and Glengarry
  • United Counties of Prescott-Russell
  • City of Cornwall

Heat Warning

A Heat Warning is issued by the Medical Officer of Health when Environment and Climate Change Canada forecast conditions of Tmax ≥ 31°C AND Tmin ≥ 20°C OR Humidex ≥ 40°C which are expected to last at least 2 days.

During a Heat Warning, everyone is at risk, however health risks are greater for: older adults, infants and young children, people with chronic illnesses, people who work in the heat, people who exercise in the heat, homeless people and low-income earners.

Heat illnesses are preventable. Follow these tips to reduce the risk of a heat illness:

  • Drink plenty of cool liquids, especially water, before you feel thirsty to decrease your risk of dehydration. Thirst is not a good indicator of dehydration.
  • Reschedule or plan outdoor activities during cooler parts of the day.
  • Wear loose-fitting, light-coloured clothing made of breathable fabric. Dress babies and young children very lightly and do not bundle them in blankets or heavy clothing.
  • Never leave people or pets in your care inside a parked vehicle or in direct sunlight.
  • Take a break from the heat by spending a few hours in a cool place. It could be a tree-shaded area, a swimming facility or an air-conditioned spot such as a public building, shopping mall, grocery store, place of worship or public library.
  • Take cool showers or baths until you feel refreshed.
  • Prepare meals that don’t need to be cooked in your oven.
  • Block sun out by closing awnings, curtains or blinds during the day.
  • Avoid sun exposure. Shade yourself by wearing a wide-brimmed, breathable hat or using an umbrella.
  • Limit your physical activity.
  • Be aware that children are unable to perspire as much as adults, and are therefore more prone to heat stress.
  • Do not allow young children with chronic respiratory conditions such as asthma to partake in sporting events or exercise.

Monitor Environment and Climate Change Canada’s website to find out when the alert is terminated.
