Weekend weather forecasts indicate temperatures in some areas of the province may reach the low 30s with possible humidex values close to 40. Manitoba Health once again reminds Manitobans to take precautions to prevent heat-related illness.
Manitobans and visitors enjoying the festivals, concerts, rodeos and other outdoor activities or working in all areas of the province should be aware of the possible impacts of high humidex levels. Age, medical conditions and strenuous activities are factors to be considered. Regions that may experience high humidex levels over the August long weekend include:
• south central areas including Winkler, Altona and Morden; and
• southwestern areas including Melita, Boissevain and Killarney.
Heat affects the body’s ability to regulate its temperature and it can lead to dehydration, heat exhaustion, other serious illnesses or even death.
While the health risks related to heat are higher for certain groups such as older adults, young children and people with chronic conditions, everyone is potentially at risk. The effects of heat can be reduced by:
• drinking plenty of liquids before feeling thirsty;
• staying inside during the hottest part of the day;
• wearing a wide-brimmed hat or using an umbrella, wearing loose-fitting, light-coloured clothing and using sunscreen if you are outdoors;
• going to a cool place such as a mall, restaurant or movie theatre for a break from the heat if there is no air conditioning at home;
• taking a cool bath, shower or swim; and
• limiting physical activities during the hotter parts of the day.
Also, remember to check on family members, neighbours and friends when it gets hot, especially older adults and people with chronic conditions who live alone. Never leave people or pets in your care alone in closed vehicles or direct sunlight.
Exposure to heat can lead to a variety of symptoms including headache, nausea, weakness, dizziness, fainting, confusion, rapid breathing and dehydration. If any of these symptoms are identified, move to a cool or shaded place immediately, drink sips of liquid, lie down and sponge with cool water if possible. Emergency medical attention may be required depending on the severity or persistence of symptoms.
