The public health unit for the Oxford and Elgin counties region has released its first heat warning of the summer.
With Environment Canada forecasting hot temperatures Tuesday that are expected to linger until Wednesday evening, Southwestern public health is urging residents to take appropriate precautions.
A heat warning is only issued when temperatures are expected to be at least 31 C and/or have a Humidex value about 40 C for at least two days while overnight temperatures are at or above 20 C.
In the Oxford and Elgin counties region, the temperatures are expected to hover in the low 30s, with humidity values that approach the 40 C mark. Additionally, overnight temperatures of 20 C or more are anticipated.
During a heat warning, residents should take steps to protect both themselves and the most vulnerable from related illnesses. Those most vulnerable to the heat include older adults, infants, young children, outdoor works and homeless people without adequate shelter, clothing or food.
Anyone experiencing physical distress because of the extreme temperatures should immediately seek medical attention by either 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, from 11 am to 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 reapply every two to three 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.
