How wildfire smoke across Canada and the US can affect mental health

Wildfire smoke is linked to health issues like heart attacks and strokes. Research is helping us understand its impacts on our wellbeing

Wildfires have devastated the western US and Canada this week, resulting in destruction, injury, evacuation and poor air quality. On Tuesday, several states – including Colorado, New Jersey, Pennsylvania, New York and Connecticut – issued air quality health advisories, according to the National Weather Service. Wildfire smoke, a major source of air pollution, is linked to severe health issues including heart attacks, strokes and lung diseases like asthma.

There is also a nascent body of research on their mental health effects, which is beginning to reveal connections that can help us better understand how these complex interactions impact our wellbeing, and inform potential solutions.
