Who is most at risk from wildfire smoke, and what symptoms should coaches watch for?

Health Canada lists infants and young children among those most at risk, along with people with existing illness or chronic conditions, adults 65 and older, pregnant people, and those who work or exercise outdoors.

Milder, more common symptoms: headaches, a mild cough, mucus, and nose, throat, eye or sinus irritation.

More serious, less common symptoms: dizziness, wheezing, chest pains, severe cough, asthma attacks, shortness of breath and heart palpitations.

Limit time outdoors, and stop or cut back strenuous activity if symptoms appear.
