As wildfire smoke continues to affect communities across Manitoba, the Manitoba Lung Association is urging residents to take air quality warnings seriously and reduce exposure where possible.
Air quality poses real health risks
Wildfire smoke contains fine particles that can travel long distances and enter the lungs, even when the fire itself is far away. These particles can worsen existing conditions like asthma, COPD and heart disease.
Juliette Mucha, President and CEO of the Manitoba Lung Association, notes that it’s important to “protect ourselves, especially for those who are vulnerable or young children, elderly, those with lung health issues.”
Even those without chronic conditions may notice symptoms like coughing or shortness of breath. When air quality deteriorates, Mucha says it’s a good idea to skip the outdoor jog and instead consider “maybe doing a spin class indoors, or going on a treadmill.”
She also recommends using the recirculate setting in vehicles and HVAC systems, explaining that “a lot of people don't use that” and could unknowingly allow smoky air into their homes.
Vulnerable groups urged to take extra care
Certain groups are more sensitive to poor air quality than others.
“We do have obviously little ones whose lungs are still developing,” Mucha says, pointing to young children, older adults, and anyone with respiratory or cardiovascular issues.
She encourages people to be proactive by checking daily updates.
Long-term exposure adds up
While symptoms from wildfire smoke may not be immediate, the long-term impacts can be serious. “People may not see the immediate effects,” Mucha remarks, but over time, continued exposure can lead to “chronic coughs or perhaps factors that lead to cancer” or worsening of conditions similar to what’s seen in long-term smokers.
“We have to be cautious in those matters,” she adds.
Using AQHI to make informed choices
The Air Quality Health Index (AQHI) is a valuable tool for managing exposure. It rates air quality on a scale of 1 to 10+ and provides guidance for outdoor activity. The higher the number, the greater the health risk.
Mucha encourages people to stay informed and aware.
“Be vigilant because a lot of people don't think,” she says, recalling a recent conversation with a caller who had been running outside for an hour while smoke levels were dangerously high.
“You have to be careful long term,” she adds, pointing out that “our wildfire smoke season is unfortunately getting longer.”
Staying safe during smoky days
The Manitoba Lung Association recommends staying indoors when possible, keeping windows and doors closed, staying hydrated, and using air filters or HEPA purifiers to keep indoor air clean. Even short-term actions, like avoiding physical exertion outdoors during poor air quality days, can reduce risk.
