BANGKOK, Thailand – The Department of Health has issued an urgent warning about rising PM2.5 levels in Northern and Northeastern Thailand. Air quality has reached “Red” and “Orange” levels, creating significant respiratory risks. Health officials urge immediate protective measures, especially for vulnerable groups, as pollution continues to affect public health.
Director-General of the Department of Health Amporn Benjaponpitak reported that as of March 28, nine provinces, including Nan, Phayao, Lampang, Lamphun, Chiang Rai, Chiang Mai, Phrae, Mae Hong Son, and Nakhon Phanom, recorded red-level air quality. Li District in Lamphun had the highest PM2.5 level at 198.3 micrograms per cubic meter. Another 28 provinces in the North, Northeast, Central, and Western regions reported orange-level conditions.
From January 1 to March 28, 2026, health monitoring indicates that over 55% of the population experienced symptoms of dust exposure, including nasal congestion, coughing, and eye irritation.
Authorities urge the public to take protective measures, such as wearing properly fitted N95 or KN95 masks, avoiding prolonged outdoor activities, especially for vulnerable groups including children, the elderly, pregnant women, and those with underlying conditions, and reducing exposure to pollution sources like open burning and vehicle emissions.
Residents should keep doors and windows closed, maintain cleanliness, and use designated clean-air rooms when pollution exceeds safe levels. Real-time air quality updates are available through applications such as Air4Thai, AirBKK, and Life Dee.
The department forecasts that PM2.5 levels may remain above safety standards this week due to stagnant weather and increased open burning. Prolonged exposure may raise the risk of cardiovascular and respiratory diseases, as well as long-term conditions like lung cancer. (NNT)
