@Alex_mckeen spoke with Dr. Chris Carlsten, Professor and Head of the Respiratory Medicine Division at UBC, and Director of the Legacy for Airway Health program at Vancouver Coastal Health.

The scenario: A runner heads out for a 5k, and as her breathing increases, she takes in more wildfire smoke.

It has combustion products that could be irritating — gaseous chemicals and small, solid particles from trees or other types of fuel that burned.

Her eyes start to water, as if pollen was out in full force. She feels a burn in her throat when she takes a breath, which takes more effort than usual.

She powers through, and the particles in the smoke begin to irritate her nose, eyes, and throat. thestar.com/news/canada/20…

A chemical reaction causes her eyes to tear, her throat to feel more rough, and her nose starts to run. Later, she’s rubbing her eyes and nose, and lets out a few coughs.

Upon returning inside, the runner showers, has coffee and sits at her work-from-home desk. Her eyes feel normal, as people, Dr. Carlsten said, are typically resilient to short-term wildfire smoke exposure.
