People more likely to be impacted by wildfire smoke should reduce or reschedule strenuous activities outdoors and seek medical attention if experiencing symptoms

In Edmonton, the Air Quality Health Index (AQHI) was projected to reach 10+ by Monday afternoon, indicating a very high risk. This level of pollution poses health risks, particularly for seniors, pregnant individuals, infants, children, and those with pre-existing health conditions or who work outdoors. Environment Canada advises these groups to limit strenuous outdoor activities and seek medical attention if symptoms arise.

the damage can begin well before that.

Health experts emphasize that even an AQHI of five or more can cause lung inflammation due to invisible fine particles. They recommend limiting outdoor time, wearing N95 masks, and taking steps like changing clothes and using air filters once indoors. These fine particles can be absorbed into the bloodstream and affect brain health.
