Malaysians should take preventive measures to face hazy days ahead, says health expert

KUALA LUMPUR: According to a health expert, the resurgence of haze pollution in Malaysia is a matter of public health concern. Malaysians need to understand the health risks associated with haze and take effective preventive measures. Dr Kow Ken Siong, a Consultant Respiratory and Internal Medicine Physician at Sunway Medical Centre, said that chronic exposure to poor air quality could lead to respiratory diseases such as asthma, chronic obstructive pulmonary disease (COPD), pneumonia, and lung cancer. Air pollution, including haze, has been linked to premature deaths, infections, and various diseases. In 2019, chronic respiratory illnesses were the third leading cause of deaths globally. These conditions accounted for nearly 20% of public hospitals and over 12% of private hospitals in Malaysia in 2020.

Due to the persistence of haze in Malaysia, it is crucial for Malaysians to understand how it affects respiratory health and take preventive measures to protect themselves. Dr Kow stated that fine particulate matters in haze, which are less than 2.5 microns in diameter, can have a lasting impact when inhaled. Short-term exposure to haze can result in acute bronchitis symptoms such as cough, phlegm, chest tightness, breathlessness, and lethargy. Vulnerable groups, including children, the elderly, and individuals with pre-existing conditions like asthma and cardiovascular diseases, face higher risks. Repeated exposure to haze over several years can worsen chronic lung conditions, increase the risk of lung cancer, and lead to frequent bronchitis episodes. Even individuals without prior health issues may develop upper respiratory symptoms and become more susceptible to viral infections.

During periods of poor air quality, Malaysians should take preventive steps. These include staying indoors as much as possible, using high-quality air purifiers with High-Efficiency Particulate Air (Hepa) filters, and staying hydrated throughout the day to mitigate haze-associated risks. For prolonged outdoor exposure, Dr Kow recommends using N95 face masks, which can filter out harmful fine particulate matter. Malaysians are also encouraged to monitor air quality through official sources, limit outdoor activities, and seek medical advice if they experience any lung or heart symptoms. It is essential to stay informed and seek timely medical attention to protect lung health during recurring haze challenges. – Bernama
