Pollution's Chronic Illness: Understanding The Hidden Health Crisis

Air pollution is a major environmental risk to human health and wellbeing. Breathing in fine particles in the air increases the chances of developing chronic obstructive lung disease (COPD), chronic bronchitis, cardiovascular disease, and lung cancer. For people with asthma or COPD, air pollution can make it harder to breathe, trigger asthma attacks, or cause wheezing and coughing. The WHO has concluded that air pollution affects children's neurodevelopmental and cognitive abilities, and can cause chronic diseases, such as childhood asthma and cancer.

Chronic obstructive pulmonary disease

Air pollution can cause a range of chronic diseases, including chronic obstructive pulmonary disease (COPD), chronic bronchitis, cardiovascular disease, and lung cancer. COPD is a progressive lung disease that makes it difficult to breathe. It is caused by long-term exposure to air pollutants, such as fine particles in the air, and is often found in people who smoke or who are frequently exposed to second-hand smoke.

People with COPD may experience symptoms such as coughing, wheezing, and shortness of breath. The disease can be managed with medication and lifestyle changes, but there is currently no cure. Reducing exposure to indoor and outdoor air pollution can help to reduce the risk of acute exacerbations of COPD.

COPD is a serious health condition that can significantly impact a person's quality of life. It is important for people at risk of developing COPD to take steps to reduce their exposure to air pollutants, such as by avoiding smoking and spending time in areas with high levels of air pollution.

In addition to outdoor air pollution, indoor air pollution can also contribute to the development of COPD. Indoor air pollutants can come from sources such as wood-burning stoves, gas stoves, and tobacco smoke. It is important for people with COPD to take steps to improve the air quality in their homes, such as by using air purifiers or ventilating their homes regularly.

Cardiovascular disease

Air pollution is a major risk factor for chronic non-communicable diseases. The most robust evidence for detrimental health effects is for fine particulate matter (PM2.5) and ozone gas. These have been the main focus of environmental health research and regulatory standards.

PM2.5 is a mixture of solid particles and liquid droplets found in the air. Some particles, such as dust, dirt, soot, or smoke, are large or dark enough to be seen with the naked eye. PM2.5 can be inhaled and contribute to cardiovascular disease and mortality. Short-term exposure to air pollution can increase the risk of heart attack, stroke, arrhythmias and heart failure in susceptible people, such as the elderly or those with pre-existing medical conditions.

Numerous animal and human studies have shown that inhalation of PM2.5 pollution can contribute to cardiovascular disease and mortality. The most widely studied personalised approaches to reducing the cardiovascular risk of air pollution include the use of face masks and in-home air purifiers.

Sources of pollution include traffic, factories, power generation, wildfires or even cooking with a wood stove. One of the most common indoor sources is smoking, which is a danger both to the person smoking and to those nearby.

Lung cancer

Air pollution is a major environmental risk to human health and wellbeing, and a major cause of mortality and morbidity worldwide. The specific disease outcomes most strongly linked with exposure to air pollution include stroke, ischaemic heart disease, chronic obstructive pulmonary disease, lung cancer, pneumonia, and cataract (household air pollution only).

There are two main types of lung cancer: non-small cell lung cancer and small cell lung cancer. Non-small cell lung cancer is the most common type, accounting for about 85% of all lung cancers. It tends to grow and spread more slowly than small cell lung cancer. Small cell lung cancer is less common, but it tends to grow and spread more quickly.

The most common cause of lung cancer is smoking, but air pollution is also a significant risk factor. Breathing in fine particles in the air, such as particulate matter (PM), carbon monoxide (CO), ozone (O3), nitrogen dioxide (NO2), and sulphur dioxide (SO2), can increase the chances of developing lung cancer over time. These pollutants can come from a variety of sources, including car exhaust, factory emissions, and wood smoke.

The symptoms of lung cancer can include a persistent cough, chest pain, shortness of breath, and wheezing. If you experience any of these symptoms, it is important to see a doctor as soon as possible. Treatment options for lung cancer may include surgery, chemotherapy, and radiation therapy, depending on the stage and type of cancer.

It is important to note that air pollution can also worsen existing respiratory conditions, such as asthma and chronic obstructive pulmonary disease (COPD). For people with these conditions, air pollution can make it harder to breathe, trigger asthma attacks, or cause wheezing and coughing. Therefore, it is crucial to take measures to reduce exposure to indoor and outdoor air pollution, especially for those with chronic respiratory diseases.

Asthma

Air pollution is a major environmental risk to human health and wellbeing, and can cause a range of chronic diseases. One of the most well-known conditions that can be caused or exacerbated by pollution is asthma.

There are several types of air pollutants that can contribute to the development or exacerbation of asthma. These include particulate matter (PM), carbon monoxide (CO), ozone (O3), nitrogen dioxide (NO2), and sulphur dioxide (SO2). The concentration of these pollutants in the air, as well as the amount of time a person is exposed to them, can impact the severity of asthma symptoms and the likelihood of an asthma attack.

Indoor air pollution can also be a significant factor in asthma development and management. On average, people spend approximately 90% of their time indoors, where the concentrations of some pollutants can be two to five times higher than outdoor concentrations. Reducing exposure to indoor and outdoor air pollution can help to reduce the onset of asthma symptoms and the risk of asthma attacks. This can be achieved through measures such as improving indoor ventilation, using air purifiers, and avoiding outdoor activities during times of high pollution levels.

Overall, air pollution is a significant factor in the development and management of asthma. By understanding the link between pollution and asthma, individuals and communities can take steps to reduce their exposure to pollutants and improve their respiratory health.

Pregnancy complications

Air pollution is a major environmental risk to human health and wellbeing, and a major cause of mortality and morbidity worldwide. It can cause a range of chronic diseases, including chronic obstructive pulmonary disease, lung cancer, cardiovascular disease, and chronic bronchitis.

Pregnant women are particularly vulnerable to the effects of air pollution. Exposure to air pollution during pregnancy has been linked to adverse outcomes, such as low birth weight and small gestational age. Studies have also suggested that air pollution exposure during pregnancy can increase the risk of other complications, including preterm birth, birth defects, and pregnancy-induced hypertension.

The specific pollutants of concern for pregnant women include particulate matter (PM), carbon monoxide (CO), ozone (O3), nitrogen dioxide (NO2), and sulphur dioxide (SO2). These pollutants can be found in both indoor and outdoor air, with indoor air sometimes being more polluted than outdoor air due to the concentration of certain pollutants.

Pregnant women can take measures to reduce their exposure to air pollution. This includes keeping up-to-date with local air quality reports and regulating daily activities accordingly. Additionally, reducing exposure to indoor air pollution sources, such as wood smoke, which can permanently damage lung tissue, can be beneficial. By taking these precautions, pregnant women can help lower the risk of potential complications for themselves and their unborn children.
