Grand Erie Public Health shares some tips to stay safe and stay cool in extreme heat
With the arrival of warmer weather, Grand Erie Public Health (GEPH) is reminding people to take precautions and stay safe when outside during extreme heat.
GEPH issues heat alerts when Environment and Climate Change Canada issues a yellow-level heat warning for any part of our region. Yellow-level warnings are typically issued when the forecast calls for two consecutive days with a maximum daily temperature of 31°C or higher during the day and a minimum temperature of 20°C or higher during the evening, or a humidex of 40°C or higher. Extended heat alerts are issued when the current heat warning extends into the third day.
Hot and humid weather can increase the risk of heat-related illness for everyone, particularly older adults, infants and young children, people with chronic health conditions, people who work or exercise outdoors, individuals experiencing homelessness, and those without access to air-conditioned spaces.
Extreme heat can worsen existing health conditions and may lead to heat exhaustion or heat stroke. Warning signs of heat-related illnesses include dizziness, headache, nausea or vomiting, weakness, confusion, fainting, and rapid breathing or heartbeat. Seek immediate medical attention if these symptoms occur.
Sun exposure during extreme heat can pose serious health risks. Anyone can develop skin cancer, regardless of skin colour. UV rays can still damage skin on cloudy or cool days.
To protect yourself, and others, in extreme heat:
-
Drink water frequently. Thirst is not an accurate measure of dehydration.
-
Avoid caffeine, alcohol, and sugary drinks.
-
Get out of the heat by spending time in an air-conditioned space or in a shaded outdoor area.
-
If air conditioning is unavailable, improve indoor airflow by using fans or creating a cross-breeze.
-
Keep indoor areas cooler by closing blinds or curtains during the day and minimizing the use of appliances that generate heat.
-
Take cool showers or baths to help lower body temperature.
-
Limit time in the sun and schedule outdoor activities for cooler times of the day. Wear light, loose clothing, sunglasses, and apply water-resistant SPF 30 sunscreen when the UV index is 3 or higher.
-
Never leave pets or children unattended in parked vehicles.
-
Regularly check-in on family, friends or neighbours, especially older adults living alone or those with health conditions.
Some medications can increase your skin’s sensitivity to sunlight. Ask your healthcare provider if you are unsure.
