The smoke from Canadian wildfires poses significant health risks, particularly for vulnerable populations such as children, the elderly, and individuals with pre-existing respiratory or cardiovascular conditions. Prolonged exposure to poor air quality can lead to respiratory issues, eye irritation, and exacerbation of chronic health problems. Major cities in the Midwest and Northeast are expected to experience unhealthy air quality levels, which could disrupt outdoor activities and impact daily life. Residents in these areas should remain vigilant and take steps to minimize exposure to the smoke.
