Hastings Prince Edward Public Health is issuing a heat warning to advise residents of Hastings and Prince Edward Counties of the predicted prolonged hot and humid weather over the Canada Day long weekend.
An extreme heat event can lead to adverse health effects.
Heat illnesses include heat stroke, heat exhaustion, heat fainting, heat edema (swelling of hands, feet and ankles), heat rash and heat cramps (muscle cramps).
Environment and Climate Change Canada issues a heat warning in Southern Ontario when there will be two consecutive days of: 31°C or more (day time) AND 20°C or more (night time) or humidex values of 40°C or more.
Heat events put everyone at risk from heat illnesses, but health risks are greatest for older adults, infants and young children, people with chronic illnesses such as breathing difficulties or heart conditions, people who work or exercise in the heat, homeless people, and people without access to air conditioning.
Watch for symptoms of heat illness, which include dizziness, headache or fainting, nausea or vomiting, rapid breathing and heartbeat, extreme thirst, and decreased urination with unusually dark yellow urine.
If you experience any of these symptoms during a heat event, immediately move to a cool place and drink liquids. Water is best.
During extreme heat, the most important thing is to keep cool and hydrated. Hastings Prince Edward Public Health recommends taking the following actions: stay well hydrated, drink before feeling thirsty (plain water is best); stay in an air-conditioned place (home, shopping mall, recreational facilities); avoid sun exposure (stay in the shade, wear SPF30+ sunscreen, a wide brimmed hat, UVA & UVB protective sunglasses, and loose-fitting long shirts and pants);
take cool showers or baths; block the sun out by closing awnings, curtains or blinds during the day; reschedule strenuous outdoor activities or plan them for cooler times of the day; and never leave people or pets in a parked vehicle or direct sunlight.
Hastings Prince Edward Public Health encourages people to visit neighbours, friends, and older family members frequently, especially those at higher risk, to make sure that they are cool and hydrated.
