Hot and humid conditions are forecast for an extended period for all of southern Manitoba, with hot temperatures and Humidex values of 40 C or more starting Saturday in some areas of the province. The Office of the Chief Provincial Public Health Officer is reminding Manitobans to take precautions to prevent heat-related illness.
Exposure to heat for too long a period can lead to dehydration, heat exhaustion, other serious illnesses or death.
Health risks related to heat are higher for groups such as older adults, young children, people on certain medications and people with chronic conditions; however, everyone is potentially at risk. The effects of heat can be reduced by:
• drinking plenty of liquids, preferably water, before feeling thirsty;
• limiting physical activities during the hotter parts of the day;
• wearing a wide-brimmed hat or using an umbrella;
• wearing loose-fitting, light-coloured clothing;
• 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 or shower; and
• limiting alcohol consumption.
Remember to check on family members, neighbours and friends when it gets hot, especially older adults and people with chronic conditions. Do not leave people or pets alone in closed vehicles or direct sunlight.
Prolonged 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 associated with heat or sun exposure, move to a cool or shaded place immediately, drink sips of liquids or water, lie down and sponge with cool water. Emergency medical attention may be required depending on the severity of symptoms. Other health conditions can be aggravated by heat and long periods of heat can have a greater effect on health.
