Chiang Mai, Thailand, is grappling with a severe air pollution crisis, as PM2.5 levels soared to 808 micrograms per cubic metre on the CCDC monitoring system, significantly exceeding the safe limit by over 20 times. This alarming situation has led to a sharp rise in pollution-related illnesses, with hospitals reporting outpatient numbers more than doubling. Common health issues among residents include allergic skin rashes, asthma flare-ups, unexplained shortness of breath, severe nasal inflammation, frequent nosebleeds, and eye irritation. The pollution crisis has impacted 11 provinces in total, putting over 1.6 million vulnerable individuals at risk. Health experts are urging residents to take precautions, such as wearing N95 masks outdoors, keeping doors and windows closed, and using air purifiers indoors to mitigate health risks.
