Chiang Mai Smog Triggers Child Nosebleeds

Chiang Mai is in the throes of its annual fire season, and the resulting smoke has pushed the city into the top tier of the world’s most polluted capitals. Residents report a surge in respiratory irritation, with parents like one mother describing her six‑year‑old’s constant nosebleeds as a stark warning sign. The haze, driven by agricultural burning and lingering dry conditions, has forced schools to close, flights to be delayed and masks to become a daily accessory. Health officials warn that prolonged exposure could exacerbate asthma, cardiovascular disease and other chronic conditions, especially among vulnerable groups such as children and the elderly.

The crisis directly threatens public health, disrupts daily life and highlights the urgent need for stronger pollution controls and emergency response plans.

Chiang Mai’s smog episode is a microcosm of a global challenge: climate‑linked fire events are worsening urban air quality, endangering millions and testing the capacity of governments to protect citizens’ health in an era of escalating environmental risk.
