In light of the foggy conditions prevailing in many parts of the country, Consultant Respiratory Physician Dr. Neranjan Dissanayake urged the public not to panic, noting that such phenomena is not abnormal and usually transient.   

However, Speaking to Daily Mirror, he recommends that individuals with respiratory illnesses be extra vigilant to avoid unnecessarily being exposed to such environments. He also said that the normal masks we use might not give significant benefit.   

Furthermore, he emphasized that the impact on individuals without respiratory problems depends on the specific substances in the air, and their concentrations measured.   
“Nevertheless, sensitive individuals should remain vigilant, he added.   

Recent data indicates a rise in air pollution levels across various parts of Sri Lanka.   

According to the National Building Research Organization (NBRO), areas including Colombo, Kandy, Puttalam, Vavuniya and Jaffna have experienced increased particulate matter in the atmosphere.   

The NBRO reports that the concentration of fine particulate matter (PM2.5) has more than doubled in recent days, reaching values between 100 and 150 on the U.S. Air Quality Index, a range that can significantly affect sensitive groups.   

As of January 29, 2025, the real-time Air Quality Index (AQI) in Sri Lanka stands at 132, categorized as ‘Poor.’ This level is particularly unhealthy for sensitive individuals, who are adviced to reduce prolonged or heavy outdoor exertion.   

As such, Dr. Dissanayake advices the public to stay informed about air quality levels and to take appropriate precautions, especially those with pre-existing respiratory conditions.
