Could your home be affecting your lung health? Dr LM Darlong shares the hidden indoor pollutants to worry about

When we think of air pollution in a cityscape, we usually tend to think of the outdoors, places where traffic fumes, construction dust, and smog are usually seen. However, according to Dr LM Darlong, the air inside a home can carry pollutants as well.

In an interaction with HT Lifestyle, Dr Darlong shared that repeated exposure to indoor pollutants may affect the respiratory system, particularly in children, older adults and people who already have asthma or other lung conditions. He went on to highlight what the pollutants are and where in our homes they may be found, which is presented as follows.

When it comes to indoor pollutants, household dust is the most common culprit. It can contain dust mites, pet dander, mould spores and fine particles that irritate sensitive airways.

In the words of Dr Darlong, “A dusty room may seem harmless, but for someone with allergies or asthma, it can be enough to trigger coughing, wheezing or breathlessness. Poor ventilation can make matters worse because these particles remain trapped indoors.”

The kitchen deserves special attention. As Dr Darlong explained, “Frying and other high-temperature cooking can release fine particles into the air. Gas stoves and other combustion-based cooking methods may produce additional pollutants.”

If the kitchen has poor ventilation, these can linger long after the meal has been prepared. Using a chimney or exhaust fan while cooking can help move the polluted air outside.

Some sources of indoor pollutants are less obvious and are objects of daily use. These include things like incense sticks, mosquito coils, scented candles, cigarette smoke, air fresheners and strongly fragranced cleaning products, all of which can release particles or volatile organic compounds.

“These may irritate the eyes, nose, throat and lungs , and can aggravate symptoms in people with sensitive airways,” noted Dr Darlong.

Dampness is another problem that is easy to miss, pointed out the doctor. A leaking pipe, seepage behind furniture or a poorly ventilated bathroom can encourage mould growth.

“Sometimes the mould is visible. Sometimes a persistent musty smell is the first clue. For people with mould allergies or asthma, exposure can worsen respiratory symptoms,” cautioned Dr Darlong.

As Dr Darlong explained, improving indoor air quality does not necessarily mean buying expensive equipment.

“Ventilate rooms when outdoor air quality is reasonable, use an exhaust while cooking, clean air-conditioning filters regularly, reduce smoke-producing products and repair leaks promptly,” he shared.

“Regular dusting and vacuuming can also reduce indoor allergens. Air purifiers may help in some situations, but they cannot compensate for a continuing source of pollution.”
