Hot and humid conditions continue in Manitoba and are forecast to remain over the next three to four days. Humidex levels of 37 to 39 are forecast for much of southern Manitoba from Thompson south to the U.S. border, with levels reaching 40, particularly in the area from Wasagaming south to the U.S. border including the Red River Valley, Winnipeg and the Whiteshell.
It is important to note the effects of heat can build up over a few days if the temperature and humidity do not drop. Plan activities carefully and look for opportunities to get a break from the heat.
The chief provincial public health officer reminds Manitobans the effects of heat can be reduced by staying properly hydrated by drinking plenty of liquids, preferably water, and limiting physical activity if possible when it’s very hot outside. If you have to spend any extended time outside, be sure to wear a hat and take breaks from the heat if possible. 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 in your care alone in closed, parked vehicles. Plan activities carefully and look for opportunities to get a break from the heat.
Exposure to heat for too long a period can lead to dehydration, heat exhaustion, heat stroke, worsening of other health conditions or, rarely, death. Symptoms of prolonged heat exposure include headache, nausea, weakness, dizziness, fainting, confusion, rapid breathing and dehydration. If any of these symptoms is associated with heat or sun exposure, move to a cool or shaded place immediately, drink sips of water, lie down and sponge with cool water. Emergency medical attention may be required depending on the severity of symptoms.
Health risks related to heat are higher for older adults, young children, people on certain medications, people with chronic health conditions and people living alone. However, everyone is potentially at risk.
