Apart From Rising AQI, Indoor Pollution Could Also Be Quietly Damaging Your Lungs- Here's How

indoor air pollution

As India continues to struggle with worsening pollution levels, the steadily rising <span>AQI</span> is triggering a range of health problems. While the toxic smog outside draws most of the attention, <span>indoor pollution</span> is another serious yet often ignored threat. According to the National Institute of Health, more than four million deaths across the world every year are linked to indoor air pollution. This largely preventable cause of disease and death needs urgent attention. Here’s a closer look at how the air inside your home may be just as harmful as the toxic air outside.

Indoor pollution is found in nearly every closed environment—homes, offices, schools, restaurants, and malls. It includes fine particles like dust mites, soot, and mould, as well as harmful gases such as carbon monoxide, nitrogen oxide, and sulphur dioxide released through everyday activities like cooking, heating, or cleaning. Though it can affect anyone, individuals with respiratory illnesses such as asthma or COPD (Chronic Obstructive Pulmonary Disease) are especially vulnerable.

<h2>Is Indoor Pollution Worse Than The Rising AQI?</h2>

The effects of poor indoor air are becoming a growing concern in India, as more people experience constant coughing, fatigue, headaches, and irritated eyes. On average, we spend nearly 90% of our lives indoors, yet studies show the air we breathe inside is two to five times more polluted than outdoor air, according to the <span>World Health Organization</span>. This poses serious risks for young children, elderly people, and pregnant women, who are more sensitive to pollutants.

<h2>Indoor Pollution Is Harmful For Your Lungs</h2>

Data from AQI India reveals that poor indoor air quality can be particularly dangerous for people with allergies or respiratory problems. Common household items such as incense sticks, air fresheners, mosquito coils, and synthetic paints release toxins that can make indoor air up to 100 times more harmful than the air outside. 

The American Lung Association notes that indoor pollutants can inflame and damage lung tissue, reduce the lungs’ capacity to fight infections, and worsen conditions like asthma, COPD, and even lung cancer. Because indoor air circulation is limited, pollutants from cooking, cleaning, or building materials can accumulate easily. Children and older adults are at greater risk since their lungs are either still developing or already weakened.

<h2>Can Indoor Pollution Lead To Asthma Issues?</h2>

Prolonged exposure to air pollutants can lead to permanent lung damage and increase the likelihood of developing chronic respiratory diseases like COPD. While it doesn’t directly cause asthma, it can aggravate existing symptoms such as coughing, wheezing, and chest tightness. 

The National Institute of Health explains that people with asthma already have inflamed and sensitive airways, making them more reactive to irritants in polluted indoor air. When these airways are exposed to allergens or chemical pollutants, inflammation worsens, mucus production increases, and airflow becomes restricted. This can lead to a rapid decline in lung function and, in severe cases, trigger a life-threatening asthma attack requiring emergency medical care.

<h2>How To Prevent Indoor Pollution?</h2>

Reducing indoor air pollution is possible with consistent preventive measures. The World Economic Forum highlights several ways to improve air quality indoors:

<strong>Proper ventilation</strong>: Good airflow is essential to replace stale, polluted indoor air with fresh air from outside. Homes that are tightly sealed to save energy can trap harmful gases and raise carbon dioxide levels, leading to headaches, dizziness, and tiredness.

<strong>Use green cleaners:</strong> Many common cleaning products contain harsh chemicals that pollute the air. Natural alternatives such as vinegar, baking soda, borax, citrus extracts, or essential oils can clean effectively without releasing toxins.

<strong>Indoor plants:</strong> Keeping plants indoors helps improve air quality as they absorb pollutants, release oxygen, and add humidity. They also help lower dust levels, making the air fresher and easier to breathe.

<strong>Use air purifiers:</strong> Air purifiers can significantly cut down indoor pollutants like pollen, dust, pet dander, and mould spores. They can also remove volatile organic compounds (VOCs) and carbon monoxide. When buying one, choose a purifier that suits the room’s size and has a high CADR (Clean Air Delivery Rate) score, which indicates how effectively it cleans the air.

By paying attention to indoor pollution, we can take a major step toward protecting our lungs and improving overall health, even as outdoor air quality continues to decline.
