Air Pollution: Breathing Toxic Air And Health Risks

Air pollution is anything that makes the air more toxic and damaging to our health. It can affect all parts of our bodies, including the health of our lungs, heart, and brain. When we breathe in air pollutants, they can enter our bloodstream and contribute to coughing or itchy eyes and cause or worsen many breathing and lung diseases, leading to hospitalizations, cancer, or even premature death. The two dominant types of air pollution in the U.S. are ozone and particle pollution. Globally, ambient air pollution in both cities and rural areas is causing fine particulate matter, which results in strokes, heart diseases, lung cancer, and acute and chronic respiratory diseases.

Air pollution can cause coughing, itchy eyes, and chest pain

Air pollution is anything that makes the air more toxic and damaging to our health. It can affect all parts of our bodies, including the health of our lungs, heart, and brain. When we breathe in air pollutants, they can enter our bloodstream and contribute to coughing or itchy eyes and cause or worsen many breathing and lung diseases, leading to hospitalizations, cancer, or even premature death.

Additionally, air pollution can cause itchy eyes. Particulate matter, such as dust, dirt, or smoke, can be large enough to be trapped by the nose and irritate the eyes. This irritation can also be caused by nitrogen dioxide (NO2) and sulfur dioxide (SO2), which are common pollutants from the combustion of fossil fuels.

Chest pain can also be a result of exposure to air pollution. Sulfur dioxide, for example, can irritate the lining of the nose, throat, and lungs, causing coughing and tightness in the chest, making it harder to breathe. Ozone, another pollutant, can reduce lung capacity and make breathing uncomfortable, which may contribute to chest pain.

The effects of air pollution on coughing, itchy eyes, and chest pain are well-documented, and these issues can be exacerbated for those with respiratory or cardiovascular conditions. It is important to minimize exposure to air pollution and to take steps to improve air quality, for the benefit of everyone's health.

It can worsen lung diseases, triggering asthma attacks and causing wheezing

Air pollution can have a detrimental impact on lung health, and for those with pre-existing lung conditions, the consequences can be even more severe. When air pollutants are inhaled, they can enter the bloodstream and cause irritation and inflammation in the airways and lungs. This can trigger asthma attacks and cause wheezing, coughing, and shortness of breath.

For people with asthma, air pollution acts as an asthma trigger, increasing the likelihood of asthma attacks and flare-ups. Asthma is a condition characterised by inflammation and narrowing of the airways, leading to symptoms such as coughing, wheezing, and difficulty breathing. Air pollution can exacerbate these symptoms, particularly when pollution levels are high. High levels of ozone, nitrogen dioxide, and particulate matter in the air can irritate the airways, making them more inflamed and triggering asthma attacks.

In addition to triggering asthma attacks, air pollution can also worsen other lung diseases, such as chronic obstructive pulmonary disease (COPD). COPD is a progressive lung disease that makes it difficult to breathe. Exposure to air pollution can further compromise lung function in individuals with COPD, making breathing even more challenging. Pollutants can irritate the airways and lungs, leading to coughing and wheezing, and potentially resulting in hospitalisations or even premature death.

The effects of air pollution on lung health are not limited to those with pre-existing conditions. Even people with healthy lungs can experience irritation and swelling of the lungs and airways. However, those with lung diseases are particularly vulnerable to the harmful effects of air pollution. Pollutants can worsen existing lung conditions, making it harder for individuals to manage their symptoms and maintain their lung health.

Air pollution is a complex mixture of solid and liquid particles, as well as gases, that can be found both outdoors and indoors. Common sources of air pollution include vehicle exhaust, smoke, road dust, industrial emissions, pollen, and chemicals used in homes. These pollutants can have a significant impact on lung health, especially for those already living with lung diseases. It is important to take steps to minimise exposure to air pollution and to prioritise clean air initiatives to protect the health of vulnerable individuals.

Air pollution increases the risk of lung infections, bronchitis, and pneumonia

Air pollution is anything that makes the air more toxic and damaging to our health. It can affect all parts of our bodies, including the health of our lungs, heart, and brain. When we breathe in air pollutants, they can enter our bloodstream and contribute to coughing, itchy eyes, and cause or worsen many breathing and lung diseases.

Air pollution increases the risk of lung infections, especially in children. It can also worsen the symptoms of those with chronic obstructive pulmonary disease (COPD). Exposure to air pollution can make it harder for people with COPD to breathe, and severe symptoms can lead to hospitalization and even death.

Air pollution also increases the risk of bronchitis. Short-term exposure to fine particles in the air can trigger acute bronchitis. Over time, breathing in these fine particles increases the chances of developing chronic bronchitis.

Additionally, air pollution increases the risk of pneumonia. High ozone levels, which are caused by a chemical reaction of gases in the presence of sunlight, have been linked to a greater risk of pneumonia. People with asthma may also experience more symptoms and need to use their reliever inhalers more often when ozone levels are high.

It can cause lung tissue swelling and irritation, even in people with healthy lungs

Air pollution is anything that makes the air more toxic and damaging to our health. It can affect all parts of our bodies, including the health of our lungs, heart, and brain. When we breathe in air pollutants, they can enter our bloodstream and contribute to coughing or itchy eyes and cause or worsen many breathing and lung diseases.

Air pollution can cause lung tissue swelling and irritation, even in people with healthy lungs. This is because the pollutants can enter the lung barrier and pass into the bloodstream, affecting all major organs of the body. These pollutants include particulate matter, nitrogen dioxide, and sulphur dioxide. Particulate matter is made up of tiny pieces of solids or liquids in the air, such as dust, dirt, and smoke. Nitrogen dioxide is a brown toxic gas that irritates the airways and makes them more inflamed. Sulphur dioxide can irritate the lining of the nose, throat, and lungs, causing coughing and tightness in the chest.

People with healthy lungs who are exposed to air pollution may experience irritation and swelling of the lung tissue. This can lead to shortness of breath, coughing, and chest pain. Even low levels of air pollution can have an impact on lung health. For people with pre-existing lung conditions, such as asthma or chronic obstructive pulmonary disease (COPD), air pollution can aggravate their symptoms and trigger asthma attacks or COPD flare-ups.

In the long term, exposure to air pollution can increase the risk of developing lung conditions, including asthma and COPD. It can also increase the risk of lung infections, such as bronchitis and pneumonia. Additionally, there is evidence that air pollution plays a role in the development of lung cancer.

To protect lung health, it is important to minimize exposure to air pollution. This includes reducing indoor and outdoor air pollution sources, such as vehicle exhaust, smoke, and industrial emissions. Individuals can take steps to reduce their exposure, but policy changes are also needed to improve air quality on a larger scale.

Air pollution can stunt lung development in children

Air pollution is anything that makes the air more toxic and damaging to our health. It can affect all parts of our bodies, including the health of our lungs, heart, and brain. When we breathe in air pollutants, they can enter our bloodstream and contribute to coughing, itchy eyes, and cause or worsen many breathing and lung diseases.

Children who are exposed to high levels of pollution may experience slowed lung development, harming their health in the short and long term. This can result in reduced lung function as adults. In addition, children are more susceptible to lung infections, such as bronchitis and pneumonia, which can be triggered or worsened by air pollution.

Air pollution also increases the risk of respiratory infections in children, which can have serious consequences. Globally, lower respiratory infections are the second leading cause of death for children under five years old. Every year, almost half a million children under five die prematurely from breathing polluted air. Evidence also suggests that air pollution exposure may harm children before they are born, as it has been linked to reduced birth weight.

The effects of air pollution on lung development in children are particularly concerning given that almost all of the global population (99%) breathe air that exceeds the recommended limits and contains high levels of pollutants. This is especially true in low- and middle-income countries, where exposure to air pollution is highest.
