Haze from Malaysia
02.08.2026

Have you noticed a burning smell lately? Or perhaps a strange odor in the air? You’ve likely experienced this recently, and it is highly possible that it is caused by the haze.
Haze is an environmental phenomenon in which invisible, dry particles float suspended in the atmosphere, severely obstructing visibility. This haze has been frequently observed across Malaysia recently. The direct cause of the haze is attributed to fine particulate matter—such as smoke and exhaust fumes—generated by large-scale open burning and forest fires on neighboring Indonesian islands like Sumatra and Kalimantan. These particles are carried directly over to the Malay Peninsula by seasonal monsoon winds, raising serious concerns about their impact on the health of local residents. Haze is typically observed in Malaysia between May and October each year, though the affected areas vary depending on the location and scale of the wildfires, as well as shifting wind directions.
Air pollution levels that exceed certain thresholds can cause various health issues. Since the impact is relatively greater on children, the elderly, and individuals with pre-existing cardiovascular or respiratory conditions, it is highly recommended to avoid prolonged outdoor activities when the haze is dense. This is because exposure to haze can trigger health problems such as sore throats, conjunctivitis symptoms (eye redness and itching), allergic rhinitis symptoms (a runny nose and sneezing), persistent coughing, and a general feeling of lethargy. Additionally, individuals with chronic cardiovascular or respiratory conditions often report a worsening of their underlying symptoms. While these symptoms generally subside as the air quality improves, concerns remain since ambient air pollution cannot be individually controlled.
The most effective preventive measures are to consistently wear a mask (high-filtration masks, that filter out fine particles are strongly recommended) and to gargle frequently. Utilizing air purifiers and humidifiers indoors is also considered highly effective in maintaining a clean environment.
If you begin to experience persistent symptoms such as a cough, runny nose, or sore throat, please do not hesitate to consult a medical professional. If left untreated, these minor symptoms could potentially lead to bronchitis or other secondary complications, making early caution and proper care essential.
