Cities Contribute To Asthma, Researchers Argue

FRIDAY, May 23, 2025 (HealthDay News) — Dirty, crowded urban environments can significantly increase a person’s risk of developing asthma, a new study says.

Cleaner, better-thought-out cities could ward off 1 of every 10 asthma cases, researchers reported recently in The Lancet Regional Health – Europe.

Asthma risk in both kids and adults is increased due to urban air pollution, dense development and limited green spaces, results show.

Cities built or altered to address these risks can help prevent asthma, researchers said.
