The Middlesex-London Health Unit has issued this summer’s second Heat Warning as hot, humid, and hazy conditions are expected to arrive on Tuesday.
The warning is expected to remain in effect until Thursday evening when the temperature will drop below 20ºC.
Environment Canada says the arrival of an incoming air mass from the Gulf of Mexico will bring hot and humid conditions into the province during the day Tuesday.
Highs of 30 to 33 degrees will be found in most areas for all three days — with the humidex making it feel more like 40 degrees Tuesday.
The Health Unit says anyone who finds they are suffering symptoms associated with extreme temperature conditions should seek medical attention immediately either by calling 911 or going to the nearest Emergency Department.
To avoid heat-related illness, follow these tips:
Drink plenty of water and natural juices throughout the day, even if you don’t feel very thirsty. Remember to take sips often and not to guzzle your drink.
Avoid drinking alcoholic beverages, coffee and cola.
Where possible, avoid spending too much time outdoors. If you must be outside, stay in the shade as much as possible. Plan outdoor activities in the early morning or evening.
Wear a wide-brimmed hat when outdoors.
Keep window shades or drapes drawn and blinds closed on the sunny side of your home.
Avoid turning on electric lights in the home.
Take a cool bath or shower periodically or cool down with cool, wet towels.
Wear loose fitting, light clothing.
Avoid eating heavy meals and using your oven.
Avoid intense or moderately intense physical activity.
Never leave a child or pet in a parked car or sleeping outside in direct sunlight.
Use fans to draw cool air at night, but do not rely on a fan as a primary cooling device during extended periods of excessive heat.
Consult your doctor or pharmacist about the side effects of any medications you are taking.
Reduce the use of personal vehicles, stop unnecessary idling; avoid using oil-based paints and glues, pesticides and gas-powered small engines.
Be aware of, and watch for, these signs and symptoms of heat illness:
Weakness or fainting
More tiredness than usual
