A home may offer shelter from outdoor pollution, but the air inside is not always free from harmful pollutants. Everyday household activities and materials, including cooking fumes, mosquito coils, cleaning chemicals, substances released from furniture, and mold growing on damp walls, can all contribute to indoor air pollution.
As people spend a significant part of their day indoors, their exposure to these pollutants can be considerable. Therefore, keeping a home clean also means paying attention to indoor air quality.
Cooking fumes and gas stoves contribute to pollution
The kitchen is one of the major sources of indoor air pollution. Cooking with gas stoves can release pollutants such as nitrogen dioxide. In addition, frying food in excessively heated oil can release fine particles into the air. Using wood, coal, or other solid fuels can produce even more smoke.
Without proper ventilation, these pollutants can accumulate indoors. Prolonged exposure to polluted air may increase the risk of respiratory problems.
To reduce these risks, use an exhaust fan while cooking, keep windows open when safe to do so, and ensure adequate ventilation in the kitchen.
Be careful when using cleaners and air fresheners
Floor cleaners, glass cleaners, air fresheners, and scented sprays are commonly used to keep homes clean. However, these products can release volatile organic compounds (VOCs) into the air.
Exposure to certain chemicals may cause eye and nose irritation, headaches, and breathing difficulties.
To minimize these risks, avoid using more sprays than necessary. Where possible, apply sprays to a cleaning cloth rather than dispersing them directly into the air. Ensure proper ventilation after cleaning and never mix different cleaning products, as this can produce dangerous gases.
Furniture and carpets can also release chemicals
Certain chemicals used in sofas, mattresses, carpets, curtains, and foam-based products can gradually enter household dust and indoor air. Researchers are also studying the potential health risks associated with certain flame-retardant chemicals used in these products.
When purchasing new furniture, it is advisable to check the materials and chemicals used in its production.
Regularly wipe furniture with a damp cloth to remove dust. Where possible, use a vacuum cleaner equipped with a high-efficiency particulate air (HEPA) filter, which can help reduce household dust.
Pay attention to the cookware you use
The cookware used at home also requires attention. If the coating of a non-stick pan becomes scratched or damaged, it is better to replace it. Avoid overheating such cookware as well.
Using wooden or other suitable soft utensils while cooking can help prevent scratches on the coating.
Certain plastic containers may release chemicals into food under specific conditions. Therefore, it is better to use microwave-safe glass or ceramic containers when heating food. Always check whether a plastic container is suitable for heating food before using it.
Damp spaces increase the risk of mold
Mold can grow on walls, ceilings, cupboards, and furniture when they remain damp for extended periods. Exposure to mold may worsen allergy symptoms, cause eye and nose irritation, and increase the risk of respiratory problems.
Such issues are more common in poorly ventilated spaces.
To reduce the risk, remove excess moisture after cooking and bathing. Drying clothes outdoors where possible and controlling indoor humidity are also important.
If mold appears on walls or furniture, simply cleaning the visible surface may not be enough. The source of moisture must also be identified and addressed.
Simple ways to improve indoor air quality
Maintaining healthy indoor air does not always require major changes. A few simple habits can help reduce pollution inside the home:
- Use an exhaust fan while cooking and ensure adequate ventilation.
- Minimize the use of mosquito coils, scented sprays, and chemical cleaners.
- Regularly remove dust from furniture and other household surfaces.
- Prevent cooking fumes and excess moisture from accumulating indoors.
- Address dampness in walls, ceilings and furniture as soon as it appears.
- Use suitable glass or ceramic containers for heating food.
Keeping a home clean is not just about having spotless floors or neatly arranged furniture. The air inside should also be healthy. Alongside protecting ourselves from outdoor pollution, identifying and addressing indoor pollution sources can play an important role in safeguarding the health of ourselves and our families.
