Southwestern Public Health issues heat warning for June 22-25

Southwestern Public Health (SWPH) issues heat warnings when Environment Canada forecasts temperatures that are expected to be at least 31°C and/or a Humidex value above 40°C for at least two days, with overnight temperatures at or above 20°C.

Environment Canada is forecasting a multi-day heat event starting Sunday and continuing through to Wednesday of next week. Daytime highs will be in the low thirties and humidex values may reach the low forties. Overnight low temperatures are expected to be in the low twenties. This heat event is expected to last until the middle of the week and possibly longer.

During a heat warning, residents should take precautions to protect themselves and the most vulnerable from heat-related illness. Those most vulnerable to the effects of the heat include older adults, infants and young children, outdoor workers, people experiencing homelessness who do not have shelter, proper clothing or food. Anyone who experiences physical distress because of extreme temperatures should immediately seek medical attention, either by calling 911 or going to the nearest emergency department.

What you should do:

• During extreme temperature conditions, stay indoors in an air-conditioned building if possible.
• Limit time in the sun when the UV Index is most intense, between 11 AM – 4 PM.
• Seek shade when outdoors, especially during mid-day.
• Drink plenty of water to stay hydrated and decrease intake of caffeinated/alcoholic beverages.
• Take cool showers or baths.
• Apply Sunscreen with SPF 30 (or higher), 20-30 minutes before going outside to ensure absorption and re-apply every 2-3 hours.
• Check regularly on children, the elderly, persons with disabilities and individuals with chronic illnesses.
• Never leave young children, the elderly or pets in a closed parked vehicle for any period.

Heat stroke is a medical emergency! Call 9-1-1 or your emergency health provider if you, or someone around you, is showing signs of heat stroke which can include red and hot skin, dizziness, nausea, confusion and change in consciousness. While you wait for medical attention, try to cool the person by moving them to a cool place, removing extra clothing, applying cold water or ice packs around the body.
