The 'Unhealthy' AQI level at Reading Airport poses health risks to the general population, with sensitive groups being particularly vulnerable. Prolonged exposure to the current air quality can lead to respiratory issues, aggravated asthma, and other health complications. Active children, adults, and individuals with pre-existing respiratory conditions are advised to avoid prolonged outdoor exertion. Everyone else, especially children, should limit outdoor activities to reduce exposure to harmful pollutants.
