The World Health Organization (WHO) warns of rising global air pollution. Does this mean outdoor exercise is unhealthy?
This increase stems partly from only 2% of cities in developing countries meeting WHO standards. Even in the Netherlands, air quality falls short in spots, especially major cities like Amsterdam and The Hague.
Does that mean exercising outdoors is unhealthy?
No—don't let air quality be an excuse to skip outdoor activity. The benefits far outweigh the risks. Even in averagely polluted cities, you could cycle for seven hours or walk for sixteen hours daily before drawbacks exceed gains.
What about the most polluted cities?
Delhi ranks among the world's most polluted, with air 10 times dirtier than London's. Yet even there, cycling five hours weekly keeps exercise benefits ahead of pollution risks.
