Indoor Air Pollution Exists
Most people usually think of air pollution as something found only outside, like vehicle smoke or factory emissions.
However, the air inside homes and buildings can also be polluted and harmful to health.
In cities, people spend nearly 70 to 90% of their time indoors, so indoor air quality is very important.
Common Sources of Indoor Pollution
In rural parts of India, indoor air pollution often comes from burning wood or solid fuels for cooking.
In urban areas, people mostly use gas for cooking, but there are still many other sources of indoor pollution.
Things like smoking, using mosquito coils, incense sticks, and chemical cleaners can pollute the air inside the house.
Even furniture, paints, wall coverings, and building materials can release harmful gases into the air.
Since many buildings in India are not fully sealed from the outside, outdoor pollution easily comes inside.
Health Effects of Indoor Air Pollution
Breathing in polluted indoor air can cause people to have headaches, tiredness, or irritation in the eyes and throat.
Some of these problems go away quickly, but long-term exposure can lead to serious diseases like asthma, heart problems, or even cancer.
When many people are in the same room with poor ventilation, the carbon dioxide level increases and can make people feel unwell.
Sometimes, the symptoms of indoor air pollution can seem like a cold, which makes it hard to notice the real cause.
Better Building Design Can Help
Buildings can be designed in a way that allows fresh air and sunlight to come in easily.
Natural light and indoor plants not only improve the mood but also help clean the air.
Hospitals and other places that need very clean air can be built with strong filters and less harmful materials.
Using fewer chemicals in paints, furniture, and cleaning products helps reduce indoor pollution.
Planning Clean Air in Buildings
Old buildings can be changed to improve air quality, but it might take more work and money.
Nowadays, many new buildings, especially hospitals, include air filters and better ventilation systems.
Designs that include natural lighting, easy movement between rooms, and good waste systems can make buildings healthier.
