With another round of scorching temperatures expected this week, and memories still fresh from last week’s heat warning, Southern Health Santé Sud is reminding residents in Portage la Prairie to take extra precautions to stay safe in the heat.
People in the prairies are no strangers to intense summer heat, but when the temperature climbs, so does the risk of serious health impacts. Heat-related illnesses can range from mild dehydration and heat exhaustion to more severe conditions like heatstroke, which can be life-threatening if not treated promptly.
“Some people are more affected by heat-related illnesses depending on their risk factors,” says Timo Gosselin, Associate Chief Medical Officer for Southern Health Santé Sud.
Those who work in high-heat environments or direct sunlight, such as construction or agriculture, may feel the effects of heat more quickly, even at temperatures as low as 28 degrees. This is because their bodies are already producing additional heat from physical exertion.
Certain medications and medical conditions can also affect the body's ability to regulate temperature, making some individuals more susceptible. Direct sun exposure can further increase the risk.
“When people get overheated, they’ll generally sweat and feel warm,” he notes. “When your body starts to max out on its capacity to cool itself down, people may stop sweating and feel like all the energy has been zapped out of them.”
Signs of heat exhaustion can also include dizziness, nausea, and muscle cramps. If not treated, symptoms can progress to heatstroke, a medical emergency that requires immediate attention. Individuals may feel confused or lethargic and experience rapid breathing or fainting.

To help prevent heat-related issues, Gosselin recommends staying out of the sun during peak hours, typically from 11 a.m. to 3 p.m., and dressing appropriately for the weather.
“If you can stay out of the sun’s radiant heat by accessing shade or clothing that blocks the sun, that can be helpful,” he adds. “Staying hydrated is also important, not just with water but also fluids that contain electrolytes.”
For those already feeling the effects of the heat, cooling down key areas of the body can help lower internal temperature quickly.
"We sweat from areas like our armpits, the top of our head, and over our brow. If you cool those areas down with a cold towel or cloth that's far below the body temperature, it allows our body to cool off as well," he continues.
Sun safety is another concern, particularly when the UV index is high.
"Today's UV index is set to be 8, and people with fair skin can get a sunburn within 20 minutes,” he adds. “You can use sunscreen, but it’s best to avoid being in direct sunlight during those peak hours or use hats and clothing to keep the sun off your skin.”
While the risks of heat and sun exposure shouldn’t be underestimated, Gosselin also wants to remind people to enjoy the season.
“Summer is short in Manitoba, and we want to make the most of it,” he says. “Everyone is excited to be outside and have a healthy summer, but we have to take some precautions when doing so.”
As temperatures continue to rise, keeping these tips in mind can help ensure that time outdoors stays safe and enjoyable for everyone.
