Air pollution contributes to chronic obstructive pulmonary disease (COPD) by exposing people to harmful substances including fine particulate matter (PM2.5), nitrogen dioxide and ozone. These irritants cause inflammation, stress, and damage to the lungs over the long term. This damage causes the airways to narrow, mucus to accumulate (bronchitis), and the air sacs to become damaged (emphysema). Long-term exposure to air pollution increases the risk of developing COPD. Short-term increases in pollution can cause serious flare-ups, leading to shortness of breath, coughing and increased infections. These flare-ups may require hospitalization and increase the risk of death, especially for vulnerable groups such as women and children who are exposed to indoor cooking fumes.
What can you do to help COPD?
COPD involves progressive diseases of the lungs, primarily chronic bronchitis and emphysema, characterized by symptoms such as persistent cough, wheezing, and trouble breathing, which can make daily activities difficult. According to the journal Springer Nature, about 50% of COPD cases occur in non-smokers, even though smoking is a known risk factor. A study from JAMA Network shows that more than 300 million people worldwide have COPD, and that number is likely to increase. “Climate change and urbanization have worsened the situation, as poor air quality increases health risks and pollution is linked to COPD, especially for vulnerable groups exposed to environmental hazards”, explains Dr Sharat Kumar Behera, pulmonologist, Manipal Hospital, Bhubaneswar.

How does air pollution affect our lungs?
To understand how outdoor air pollution affects us, we need to know what it includes: particulate matter (PM2.5 and PM10), nitrogen dioxide (NO₂), and sulfur dioxide (SO₂). PM2.5 is particularly harmful. These tiny particles are so small that they can penetrate deep into the lungs and even enter the bloodstream, causing systemic inflammation and respiratory problems. “For people with lung problems, outdoor pollution worsens their symptoms. As a result, they go to hospitals more often and health care costs are higher,” the doctor says.
Don’t ignore indoor air pollution
Many people focus on outdoor air pollution, but we often ignore indoor air quality. Cooking with fuels such as wood or kerosene produces harmful fumes that may increase the risk of COPD. According to the National Institute of Environmental Health Sciences (NIEHS), most people spend more than 90% of their time indoors, so indoor air quality is a serious concern. A study published in the journal Indoor Environment found that long-term exposure to indoor air pollutants can lead to persistent inflammation of the airways. “This can lead to various respiratory problems, which is especially worrisome for women and children living in rural and semi-urban areas, as they are often exposed to these hazardous environments,” says the pulmonologist.
Does air pollution affect COPD?
For people with COPD, air pollution can seriously worsen symptoms when pollution levels are high. Many patients experience sudden shortness of breath, persistent cough, and increased mucus production. Pollution not only worsens symptoms but also weakens the lungs’ natural ability to protect themselves. “Pollutants can damage the body’s mechanisms that clear mucus and germs from the lungs, making people more susceptible to infections like pneumonia,” says Dr. Behera. When this happens, lung function can rapidly decline, creating a dangerous cycle that requires immediate medical attention.
Effect of air pollution on children
Polluted air affects not only our health today but also the health of future generations. “Children who breathe high levels of pollution while their lungs are still developing may not have healthy lungs that can lead to reduced lung capacity in adulthood,” the expert says. Children who grow up in polluted areas are more likely to develop respiratory problems like asthma and COPD later on. “Parents and caregivers should be aware of the long-term effects of air pollution and help by advocating for clean air in their communities and supporting policy changes,” the pulmonologist says.
How to reduce the ill effects of air pollution?
First, protect yourself by wearing a mask on days when pollution levels are high, ensure adequate ventilation in your homes and choose cleaner cooking methods like LPG or electric stoves. We need to push for policy changes in urban planning that prioritize the creation of green spaces and the reduction of emissions from cars and industry. Experts share, “Public awareness campaigns can educate at-risk people about causes of COPD that are not related to smoking and highlight the importance of air quality.”
