How Clean Air Improves Our Health And Environment

Air pollution is a serious threat to human health and the environment. It is the fourth leading cause of global premature deaths, with 5.5 million lives lost in 2013 alone. The good news is that reducing air pollution has been shown to have significant and rapid health benefits. For example, banning smoking in public places in Ireland reduced overall mortality from smoking-related diseases and improved respiratory symptoms within 1-2 months. Similarly, shutting down a steel mill in Utah for 13 months halved the concentration of pollutants in the air and led to reduced hospital admissions for respiratory illnesses, especially in children.

The benefits of clean air extend beyond human health. Clean air can also positively impact animal and plant life and address social issues such as crime and poverty rates. Additionally, reducing air pollution can help tackle climate change. Short-lived climate forcers (SLCFs), such as methane and black carbon, have a significant impact on the amount of solar energy retained by the Earth. By targeting these SLCFs, we can achieve benefits for both human health and the climate.

Furthermore, improving air quality can have economic advantages, reducing medical costs and increasing worker productivity. The implementation of pollution control measures can also lead to cost savings, as the benefits often outweigh the costs of implementing such measures.

Overall, reducing air pollution is crucial for protecting human health, the environment, and the planet. The benefits are far-reaching and highlight the urgency of global efforts to improve air quality.

Reduced risk of respiratory and irritation symptoms

Reducing air pollution is beneficial as it lowers the risk of respiratory and irritation symptoms. Air pollution can cause both acute and chronic respiratory issues, affecting multiple organs and systems in the body. Pollutants such as nitrogen oxides, ozone, sulphur dioxide, carbon monoxide, and particulate matter affect different parts of the respiratory tract, leading to symptoms such as nose and throat irritation, coughing, sneezing, and respiratory infections.

Children, older adults, and individuals with pre-existing cardiovascular or respiratory conditions are at an increased risk of experiencing these adverse health effects. Inhaling polluted air can also aggravate pre-existing respiratory conditions like asthma, chronic obstructive pulmonary disease, and heart disease. Additionally, air pollution has been linked to reduced lung function and increased susceptibility to respiratory infections.

By reducing air pollution, we can lower the concentration of harmful pollutants in the air, thereby mitigating these respiratory issues and improving overall respiratory health, especially in vulnerable populations. This can lead to a decrease in the number of hospitalizations and premature deaths caused by respiratory diseases.

Furthermore, reducing air pollution can also lessen irritation symptoms. For example, sulphur dioxide and aldehydes, which are common air pollutants, can cause irritation in the upper respiratory tract by dissolving into the water around the nasal mucosa and triggering an inflammatory response.

Overall, reducing air pollution is crucial to lowering the risk of respiratory and irritation symptoms, improving public health, and reducing the burden of respiratory diseases on individuals and healthcare systems.

Improved heart and respiratory health

Air pollution is a major environmental risk to health. It is linked to heart disease and respiratory issues, and can trigger heart attacks or strokes. One in three Americans has heart disease, which can be worsened by air pollution.

Breathing clean air can reduce the possibility of disease from stroke, heart disease, lung cancer, and acute and chronic respiratory illnesses such as asthma. Lower levels of air pollution are better for heart and respiratory health in both the long and short term.

The Impact of Air Pollution on Heart Health

Air pollution can increase the risk of heart attack, stroke, arrhythmias, and heart failure in susceptible people, including the elderly or those with pre-existing medical conditions. Long-term exposure to air pollution increases the risk of death. Current scientific research suggests that air pollution aids the development and progression of atherosclerosis, or plaque buildup in the artery walls, which causes heart disease. Pollution may also play a role in high blood pressure and diabetes.

The Impact of Air Pollution on Respiratory Health

Air pollution can cause respiratory disease and increase the risk of lung cancer. It can also trigger or exacerbate asthma and other respiratory illnesses.

The Impact of Reduced Air Pollution on Heart and Respiratory Health

Reducing air pollution can lead to improved heart and respiratory health, lowering the risk of the aforementioned diseases and health issues. This is especially important for vulnerable populations, including the elderly and those with pre-existing cardio-respiratory diseases, who tend to experience more complicated health problems after exposure to air pollution.

Examples of Improved Heart and Respiratory Health Due to Reduced Air Pollution

• A study of 500,000 teens and adults over 16 years found that reducing PM2.5 air pollution by 10.5 μg/m3 led to an 8-18% decrease in the risk of ischemic heart disease, heart failure, arrhythmias, and cardiac arrest.
• Research by the EPA found that reducing exposure to PM2.5 over a few hours to weeks can trigger cardiovascular disease-related heart attacks and death. Longer-term reductions in exposure can lead to decreased risk of cardiovascular mortality and increases in life expectancy.
• A study of 8,111 adults in six U.S. cities over 14-16 years found that mortality rates were 1.26-1.37% higher among people living in the most polluted cities compared to the least polluted cities.
• A study of 23 patients showed significant rises in diastolic blood pressure after a two-hour exposure to PM2.5 and ozone.
• A study of 21 U.S. cities found an association between NO2 and PM10 exposure and the risk for hospitalization.
• A study of 50 million people living in the 20 largest U.S. cities found that a 10 μg/m3 increase in PM10 on the day before death was associated with a 0.68% increase in cardiopulmonary mortality.
• A similar study of 43 million people in 29 major European cities found that for every 10 μg/m3 rise in PM10, the risk of cardiovascular death increased by 0.76%.

Reduced risk of cancer

Reducing air pollution lowers the risk of cancer by limiting exposure to fine particulate matter, which can cause changes in airway cells that trigger lung cancer. Nearly half of lung cancer cases in people who have never smoked are estimated to be related to air pollution.

According to the World Health Organization, 99% of the world's population breathes unhealthy air, and air pollution causes nearly seven million deaths per year. The risks associated with air pollution are similar to those caused by smoking tobacco. In addition to lung cancer, air pollution is linked to other types of cancer, including bladder cancer, breast cancer, and cancers of the digestive organs and urinary tract.

The benefits of reducing air pollution are far-reaching, not only in preventing cancer but also in improving overall health. Lowering air pollution increases green spaces, promotes active transportation like walking and cycling, and leads to a healthier diet and increased physical activity, all of which contribute to a reduced risk of developing cancer.

Furthermore, reducing air pollution improves air quality, making it easier for people to engage in physical activities. Poor air quality may limit people's ability or opportunity to be physically active, which is essential for maintaining good health.

By taking action to reduce air pollution, we can not only lower the risk of cancer but also create a healthier environment for ourselves and future generations.
