Video: How does wildfire smoke affect our lungs?

July 14, 2025 — 

The spread of uncontrolled wildfires has caused significant destruction and evacuations of communities across Manitoba this summer. With over 100 active wildfires in the province as of July 14,  it doesn’t show any sign of slowing down. One of the other negative effects of the wildfires is the constant lingering smoke that can pose health risks, especially to those with health conditions that make them more vulnerable.

Dr. Andrew Halayko is a research scientist and professor in the Max Rady College of Medicine and a Canada Research Chair in lung pathobiology and treatment. We spoke with Halayko about what exactly the harmful chemicals contained in wildfire smoke are and who is most at risk, along with some of the best ways to mitigate the danger when significant wildfire smoke is present.
