The start of the week is going to be a hot and sticky one across the London region.
The daytime high on Monday is expected to reach 31 C, but will feel five degrees higher than that because of the humidity. That has prompted the Middlesex London Health Unit to issue a one-day heat alert.
“Many people across the region are enjoying holidays this week and their planned activities may include spending time outdoors taking part in fun summer activities. Some of the important things to add to those plans are a hat, light clothing and of course plenty of water to drink,” Public Health Inspector Randy Walker said in a statement. “It is vitally important to build those things into your summer fun plans, and that also includes using sunscreen and taking frequent breaks from the heat and cooling off in an air-conditioned space or even taking a cool bath.”
Relief from the scorching heat and humidity will come overnight when the temperature is forecast to fall to 17 C. Environment Canada is calling for rain on Tuesday which will help to further clear out any remaining humid air. By Wednesday, the London-area returns to the average seasonal temperature for this time of year - 26 C.
To avoid heat-related illness, health officials advise people to take the following steps:
• 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. • Never leave a child or pet in a parked car or sleeping outside in direct sunlight. • Avoid drinking alcoholic beverages, as well as coffee and cola. • When possible, avoid spending too much time outdoors. If you must be outside, seek shade as much as possible. Plan outdoor activities in the early morning or evening. • Wear a wide-brimmed hat when outdoors. • Keep shades or drapes drawn and blinds closed on the sunny side of your home. • Avoid turning on electric lights in your 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. • 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. • Reduce the use of personal vehicles, stop unnecessary idling; avoid using oil-based paints and glues, pesticides and gas-powered small engines.
Symptoms of heat-related illness include rapid breathing, weakness or fainting, fatigue, headache, and confusion. Anyone experiencing these symptoms should get help from a medical professional.
