KFL&A Public Health Issues Extended Heat Warning

Kingston – KFL&A Public Health is issuing an extended heat warning to advise residents in Kingston, Frontenac and Lennox & Addington area that the extended nature of the hot and humid weather that will be affecting parts of this area, may have adverse health effects.  According to Environment Canada, the hot weather conditions will start on Saturday of the Canada Day long weekend, with expected daytime highs in low to mid thirties, overnight temperatures only in the low twenties and with humidex values into the mid-40’s. There is uncertainty when the heat event will end. Current indications suggest the heat could persist into the middle of next week. 

A heat warning is issued by Environment Canada for the KFL&A area when the forecasted maximum temperature is expected to be greater than or equal to 31⁰C, and the lowest nighttime temperature is anticipated to be at or above 20⁰C for a period of 2 days or longer. A warning will also be issued if the anticipated humidex is 40⁰C or warmer for a period of 2 days or longer.

Humidex values describe how the hot and humid weather feels to the average person. It combines the temperature and humidity readings into one number to reflect the perceived temperature.  The higher the humidex, the harder it is for perspiration to evaporate to cool the body.

During heat events, everyone is at risk; however, the health risks are greatest for:

• older adults,
• infants and young children,
• people with chronic illnesses or who take certain medications,
• people who work or who exercise in the heat, and
• people without access to air-conditioned spaces.

Being prepared is key to protecting communities from negative health impacts.  KFL&A Public Health recommends taking the following actions to stay cool:

• Drink plenty of cool liquids, especially water, before feeling thirsty.
• Avoid sun exposure, for example by sitting under a tree, wearing a wide-brimmed, breathable hat, or using an umbrella.
• Take a break from the heat by spending a few hours in a cool place, such as a public space that is air conditioned in KFL&A.
• Reschedule strenuous outdoor activity or plan outdoor activities during cooler parts of the day.
• Wear loose-fitting, light-coloured clothing made of breathable fabric.
• Block the sun out by closing awnings, curtains, or blinds during the day.
• Never leave people or pets that are in your care inside a parked vehicle or in direct sunlight.

KFL&A Public Health encourages people to visit neighbours, friends, and older family members frequently, especially those who are chronically ill, and those at higher risk, to make sure that they are cool and hydrated.
