Diseases Caused by Air Pollution and How Air Purifier can help

The alarming air pollution levels have brought about disastrous health consequences for millions of people worldwide in the past few decades. It comprises both outdoor as well as indoor air pollution.

The outdoor pollution results from vehicular emissions, industrial pollution, construction sites, crop burning, forest-fire, fuel combustion, etc. Indoor pollution is caused by electronic equipment, dust, pets, cooking fumes, and household furniture.

Air pollution has not only led to severe environmental damage but also given rise to various life-threatening diseases. Contrary to popular perception, air pollution causes respiratory disorders and affects the heart, brain, eyes, and other body organs.

Common Diseases Caused by Air Pollution

Chronic Obstructive Pulmonary Disease (COPD)

Chronic obstructive pulmonary diseases (COPD) refer to respiratory disorders that make it difficult for individuals to breathe normally. It includes bronchitis and emphysema, and both these conditions result from the damage caused by air pollutants to the lungs.

In addition to outdoor pollution, indoor air pollutants may lead to inflammatory lung disease and worsen COPD symptoms by obstructing the flow of air in the lungs.

When you are exposed to scented products, allergens, smoke, paints, etc., these elements may aggravate COPD. As per the WHO’s data, COPD is responsible for approx 25% of deaths in adults.

Lung Cancer

Lung cancer refers to the uncontrolled proliferation of the cells within the lungs. It is a severe life-threatening condition caused by various air pollutants, particulate matter smoking, and exposure to various indoor pollutants.

The carcinogenic agent PM 2.5 is the main culprit that triggers lung cancer when breathed into the lungs. Those individuals who live or work in a congested area with minimal ventilation are also at higher risk of lung cancer.

Lower Respiratory Tract Infections (LRTI)

Lower respiratory infection (LRTI), such as pneumonia, results from the inflammation of the lungs’ air sacs. In this condition, the air sacs of the lungs are filled with fluid or pus. This results in difficulty in breathing, fever, coughs, and chills.

The kids are more vulnerable to LRTI like pneumonia as they are more exposed to indoor air pollution and their lungs are still in developing stages. The indoor air pollutants significantly increase the risk of LRTI among adults as well.

As per WHO, the LRTI led to approx 28% of adult deaths every year.

Cardio-Vascular Diseases 

The cardiovascular diseases caused by outdoor and indoor air pollutants include coronary heart disease or ischemic heart disease.

The air pollutants result in a build-up of calcium and other fatty materials within the coronary artery and obstruct blood circulation.

Thus, air pollution leads to blockages in the blood vessels and prevents blood from reaching various bodies. It causes increased incidences of ischemic heart diseases and may even lead to a heart attack.

Brain Strokes

The accumulation of the deadly particulate air pollutants within the blood vessels may create blockages in the arteries carrying blood to the brain and obstruct blood circulation. This life-threatening condition may result in brain strokes.

Weaker Immunity and Respiratory Disorders in Unborn Babies

The expecting mothers are at high risk of exposure to indoor air pollutants. These air pollutants enter the mother’s body when they breathe in polluted air. These interfere with the normal growth and development of unborn babies.

Once the babies affected by the air pollutants are born, they may have weaker immunity or lung or respiratory disorders. Moreover, indoor air pollutants may result in ENT infections in the more active kids and inhale in more air during playing.

Decreased Life Span

The continuous exposure to outdoor and indoor air pollutants may lead to the decreased life span of the individuals. It interferes with the normal body functioning and sound health of the individuals and adversely affects their longevity.

Studies have shown that individuals living in highly polluted areas of cities are more likely to have a lesser life span than individuals residing in natural and pollution-free rural areas.
