Running in poor air quality can pose significant health risks, according to Runstreet. The Air Quality Index (AQI) helps determine safe levels for outdoor activities. AQI scores range from 0 to 500, with higher numbers indicating worse air quality. Green (0-50) and yellow (51-100) ratings are generally safe for most runners, while orange (101-150) and red (151-200) ratings can be harmful, especially for vulnerable groups.
Wildfire smoke and pollution from vehicles contribute to bad air quality. NYC experienced severe air quality due to smoke from Canadian wildfires. Officials advised against outdoor exercise during such events. Knowing the AQI helps runners decide whether to exercise indoors or outdoors. Staying informed about air quality can prevent long-term health issues. Read more travel coverage.
For runners, understanding AQI ratings is crucial. Green and yellow ratings allow outdoor running, while orange, red, purple, and maroon ratings (201-500) require indoor workouts. This knowledge helps maintain health and avoid risks associated with poor air quality. Staying indoors during high AQI days protects both short-term and long-term health.
