The Regional Municipality of York issues heat advisory

Take extra precautions to reduce the risk of illness during hot and humid weather
NEWMARKET - The Regional Municipality of York has issued a heat advisory today as a result of hot temperatures and high humidity. York Region issues a heat advisory when Environment Canada issues a Special Weather Statement relating to extreme heat and humidity in our area. Environment Canada has indicated that cooler and less humid conditions are expected for Wednesday.
Extreme heat can cause heat-related illnesses and everyone is at risk. Risks are greatest for older adults, infants and young children, people who work or exercise in the heat, or have chronic illnesses including breathing difficulties, heart conditions or psychiatric illnesses. Give extra attention to neighbours, friends and older family members, especially those who are chronically ill, to ensure they are cool and hydrated.
Warning signs of heat-related illness can include dizziness, headache, nausea or vomiting, weakness and confusion. If you experience any of these symptoms, seek medical attention immediately.
The following preventative measures can help protect your health during hot and humid weather:
Find ways to stay cool
• Stay indoors in cool, well-ventilated areas
• Use fans with caution – keep a window or door open to bring in cooler air from outside
• If you do not have air conditioning in your home, go to places that do, including shopping malls, local libraries, public pools and community centres
• Wear loose-fitting, light-coloured clothing made of breathable fabric such as cotton
• Never leave people or pets inside a parked vehicle or in direct sunlight
Drink extra fluids
• Drink plenty of cool liquids, especially water before feeling thirsty
• Increase your fluid intake regardless of your level of activity
Reduce physical activity, especially in the full sun
• If you must be outdoors in the heat, rest frequently to allow your body temperature to cool down 
• Avoid sun exposure by wearing a wide-brimmed, breathable hat or use an umbrella
• Reschedule or plan outdoor activities during cooler parts of the day
• Reduce sun exposure between 11 a.m. and 4 p.m. or when the UV Index is three or higher
• Wear sunscreen SPF 30 or higher 
Poor air quality is also common during extreme heat events. Check the Air Quality Health Index at To access Environment Canada’s special weather statements, please visit
