Air pollution can have a significant impact on human health. Pollutants in the air can cause inflammation, oxidative stress, immunosuppression, and mutagenicity in cells throughout the body, impacting the lungs, heart, brain and other organs. This can lead to a range of health problems, including respiratory issues, heart disease, lung cancer, strokes, and even premature death.

What You'll Learn
Irritation and inflammation of the lungs
Air pollution can cause irritation and inflammation of the lungs. The main pathway of exposure from air pollution is through the respiratory tract. Pollutants such as dust, fumes, gas, mist, odour, smoke or vapour can be breathed in, causing irritation and inflammation. These pollutants can penetrate and lodge deep inside the lungs, causing irritation and damaging the lining of the respiratory tract. Smaller, more harmful particles can penetrate the lung barrier and enter the bloodstream, affecting all major organs of the body. This can lead to systemic inflammation and an increased risk of heart and respiratory diseases, lung cancer and strokes.
Ozone, nitrogen dioxide and sulfur dioxide are major factors in causing asthma and making it worse. These pollutants can also cause bronchial symptoms, lung inflammation and reduced lung function. For people with asthma or chronic obstructive pulmonary disease (COPD), air pollution can make it harder to breathe, trigger asthma attacks, and cause wheezing and coughing. Even people with healthy lungs are susceptible to irritation and swelling.
Air pollution can also worsen COPD symptoms, making it even harder for people with this disease to breathe. Severe symptoms can lead to hospitalisation and even death. In addition, some studies show that exposure to air pollution may increase the risk of low infant birth weight and infant mortality.
Premature death is another potential consequence of exposure to unhealthy air, with both short-term and long-term exposure capable of shortening life. Almost every organ in the body can be impacted by air pollution, as some pollutants are small enough to penetrate into the bloodstream via the lungs and circulate throughout the entire body.

Increased risk of heart disease
Air pollution can have a number of negative impacts on human health. One of the most significant risks is the increased likelihood of developing heart disease. This is due to the presence of contaminants in the atmosphere, such as dust, fumes, gas, mist, odour, smoke or vapour. When these pollutants are breathed in, they can enter the bloodstream via the lungs and circulate throughout the body. This can lead to systemic inflammation, which is a key risk factor for heart disease.
The impact of air pollution on heart health is particularly concerning given that it can affect people of all ages and backgrounds. Even those with healthy lungs are susceptible to the negative effects of air pollution, which can include irritation and swelling of the lung tissue. For those with pre-existing heart conditions, the risks are even greater.
In addition to the direct impact on the heart, air pollution can also contribute to other risk factors for heart disease. For example, it can worsen respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). This can lead to further strain on the heart as it has to work harder to pump oxygen-rich blood throughout the body.
The effects of air pollution on heart health are not limited to those who are directly exposed. In fact, the impact can be far-reaching. Studies have shown that exposure to air pollution during pregnancy can increase the risk of low infant birth weight and infant mortality. This highlights the potential long-term consequences of air pollution on heart health, even from early stages of life.
Overall, the link between air pollution and heart disease is a serious public health concern. It underscores the importance of taking measures to reduce air pollution and protect the health of individuals and communities. By addressing this issue, we can not only improve heart health but also potentially reduce the burden of other related health conditions.

Respiratory tract damage
Air pollution can have a significant impact on the respiratory tract. The main pathway of exposure from air pollution is through the respiratory tract, and breathing in pollutants can lead to inflammation, oxidative stress, immunosuppression, and mutagenicity in cells throughout the body.
Particles with a diameter of 10 microns or less can penetrate and lodge deep inside the lungs, causing irritation, inflammation, and damage to the lining of the respiratory tract. Smaller, more harmful particles with a diameter of 2.5 microns or less can penetrate the lung barrier and enter the bloodstream, affecting all major organs of the body. These pollutants increase the risk of heart and respiratory diseases, as well as lung cancer and strokes.
For people with asthma or chronic obstructive pulmonary disease (COPD), air pollution can make it harder to breathe, trigger asthma attacks, and cause wheezing and coughing. Even those with healthy lungs are susceptible to irritation and swelling from air pollution. Exposure to air pollution can worsen COPD symptoms, leading to hospitalisation and even death in severe cases.
Ozone, nitrogen dioxide, and sulfur dioxide are particularly harmful to the respiratory tract, causing asthma, bronchial symptoms, lung inflammation, and reduced lung function.

Asthma and other bronchial symptoms
Air pollution can have a significant impact on human health. The main pathway of exposure from air pollution is through the respiratory tract.
Air pollution can cause and worsen asthma and other bronchial symptoms. Ozone, nitrogen dioxide and sulfur dioxide are all pollutants that can cause these symptoms. Particles with a diameter of 10 microns or less can penetrate and lodge deep inside the lungs, causing irritation and inflammation and damaging the lining of the respiratory tract. Smaller particles, with a diameter of 2.5 microns or less, can penetrate the lung barrier and enter the blood system, affecting all major organs of the body. These pollutants increase the risk of heart and respiratory diseases, as well as lung cancer and strokes. For people with asthma, air pollution can make it harder to breathe, trigger asthma attacks, and cause wheezing and coughing. These effects can be especially harmful for those living with chronic lung diseases.

Premature death
Air pollution can cause premature death. Science shows that both short-term and long-term exposure to unhealthy air can shorten your life and lead to premature death. Air pollution is the presence of one or more contaminants in the atmosphere, such as dust, fumes, gas, mist, odour, smoke or vapour, in quantities and duration that can be injurious to human health. The main pathway of exposure from air pollution is through the respiratory tract.
Breathing in these pollutants leads to inflammation, oxidative stress, immunosuppression, and mutagenicity in cells throughout our body, impacting the lungs, heart, brain and other organs. Almost every organ in the body can be impacted by air pollution. Some air pollutants are small enough to penetrate into the bloodstream via the lungs and circulate throughout the entire body, leading to systemic inflammation and carcinogenicity.
Particles with a diameter of 10 microns or less can penetrate and lodge deep inside the lungs, causing irritation, inflammation and damaging the lining of the respiratory tract. Smaller, more health-damaging particles with a diameter of 2.5 microns or less can penetrate the lung barrier and enter the blood system, affecting all major organs of the body. These pollutants increase the risk of heart and respiratory diseases, as well as lung cancer and strokes.
For people with asthma or chronic obstructive pulmonary disease (COPD/emphysema or chronic bronchitis), air pollution can make it harder to breathe, trigger asthma attacks, or cause wheezing and coughing. Exposure to air pollution can make it even harder for people with COPD to breathe. Severe symptoms can lead to hospitalisation and even death.
