Hot and humid conditions continue to be forecast for much of southern Manitoba over the next few days with humidex values potentially rising close to 40. Manitoba Health is reminding Manitobans to take precautions to prevent heat-related illness.
Environment Canada forecasts predict the high heat and humidity values will be seen across the southern part of the province including Melita, Boissevain, Virden, Brandon, Carman, Portage la Prairie, Winnipeg, the Morden-Winkler-Altona and Steinbach regions and surrounding areas. The Whiteshell, Interlake and Lake Winnipeg beaches are also included.
Exposure to heat for too long a period can lead to dehydration, heat exhaustion, other serious illnesses or even death. Heat that persists over many days, particularly without much cooling at night, increases the risk to people’s health.
Health risks related to heat are higher for certain groups, such as older adults, young children and people with chronic conditions; however, everyone is potentially at risk. The effects of heat can be reduced by:
• drinking plenty of non-alcoholic liquids, preferably water, 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.
Remember to check on family members, neighbours and friends when it gets hot, especially older adults and people with chronic conditions. Never leave people or pets alone in closed vehicles or direct sunlight.
Exposure to heat can lead to a variety of symptoms including headache, nausea, weakness, dizziness, and dehydration. If any of these symptoms are identified, move to a cool or shaded place immediately, drink sips of liquids or water, lie down and sponge with cool water, if possible. Emergency medical attention may be required depending on the severity and persistence of symptoms. Confusion or decreased mental alertness are indications of the need for urgent medical care.
