Should you exercise in wildfire smoke? Here's what experts say.

Many runners assume a brisk jog clears the lungs, but in wildfire season the same activity can trigger cough, wheeze and reduced performance. The culprit is dense particulate matter from wildfires that drifts into urban air, turning a routine run into a respiratory stressor. UW Medicine advises athletes to scale back intensity, use respirators, or shift workouts indoors during peak smoke events.

Military.com recommends indoor cardio alternatives until conditions improve. They also flag early signs such as shortness of breath, chest tightness, or eye irritation as signals to stop activity. Facilities with air filtration are highlighted as safer venues for high‑intensity sessions.

The next step for joggers and cyclists is to track real‑time air‑quality indices, heed any public‑health advisories, and stay alert for updated guidance from sport‑medicine bodies as wildfire patterns evolve. Athletes should also consider flexible training schedules to shift sessions to early mornings or evenings when smoke levels dip.
