Air Pollution: The Unseen, Unfelt Danger

Air pollution is a mix of gases, droplets, and particles that reduce air quality. It can be caused by cars, buses, airplanes, industry, construction, and more. The effects of air pollution on the human body are varied and depend on the type and level of pollution. Some common symptoms of exposure to air pollution include irritation of the eyes, nose, and throat, coughing, wheezing, and chest pain. In some cases, air pollution can lead to more serious health issues such as lung and heart conditions, especially in children and older adults. To protect against the harmful effects of air pollution, individuals may need to take precautions such as staying indoors, wearing masks, or using air purifiers.

Air pollution can cause irritation to the eyes, nose and throat

Air pollution is a mix of gases, droplets, and particles that reduce air quality. It can be caused by cars, buses, airplanes, industry, construction, tractors ploughing fields, trucks, and more. Certain pollutants in the air can cause irritation to the eyes, nose, and throat.

Airborne pollutants can disrupt the tear film that keeps our eyes lubricated, leading to dryness and irritation. This can cause a gritty or burning sensation in the eyes, along with redness, tearing, and sensitivity to light. Outdoor enthusiasts who spend extended periods outdoors, especially in sunny or windy environments, are more prone to these issues.

Air pollution can also cause nasal congestion due to inflammation and swelling in the nasal passages. This can lead to a stuffy nose and make breathing challenging. Prolonged exposure to harmful pollutants can also damage the cells in the throat and neck region, leading to potential long-term health effects. Throat irritation, dry throat, and a tickly cough are common symptoms of air pollution exposure.

In addition to the eyes, nose, and throat, air pollution can also affect the ears. Long-term exposure to environmental pollution can lead to permanent damage to the ears, causing chronic ear infections and ear pain. Children are often more vulnerable to the effects of air pollution on their ears due to their developing immune systems and smaller airways.

To protect yourself from the harmful effects of air pollution, it is important to stay indoors as much as possible during high-pollution days and limit outdoor activities. Using air purifiers, ensuring proper ventilation, and avoiding smoking indoors can also help improve indoor air quality.

It can worsen lung problems, especially asthma

Air pollution is a mix of gases, droplets, and particles that reduce air quality. It can be caused by cars, buses, airplanes, industry, construction, and more. Ground-level ozone is the major pollutant in most cities. It is created when engine and fuel gases interact in the presence of sunlight.

Ozone is an invisible gas and a common air pollutant. It is helpful in the upper atmosphere, but when found in the air we breathe, it can be problematic. High levels of ozone can reduce lung function and lead to inflammation and swelling in the airways. This can cause symptoms such as coughing, throat irritation, watery eyes, and chest pain.

Air pollution can worsen lung problems, especially asthma. People with asthma are at greater risk from breathing in small particles and irritating gases, which can irritate the airways and trigger asthma symptoms. Pollutants can make the lungs more sensitive to allergens and increase the likelihood of respiratory infections, which can bring on asthma attacks.

Several studies have found a link between air pollution and asthma. Children living near busy roadways with high levels of particulate air pollution are more likely to develop asthma and other breathing disorders. Air pollution is also associated with increased hospital visits and, in some cases, early death due to asthma.

If you or your child has asthma, it is important to be aware of air pollution levels and take precautions on high-pollution days. This may include limiting outdoor activities, reducing the intensity of workouts, and increasing medication as advised by your doctor.

It can lead to cardiovascular issues, such as heart attacks and strokes

Air pollution is a complex mixture of gases, droplets, and particles that reduce air quality. It can be caused by various sources, including transport, industry, and wildfires, and it has detrimental effects on human health, particularly when it comes to cardiovascular issues.

The impact of air pollution on cardiovascular health is a growing concern. Studies have shown a strong link between air pollution and an increased risk of cardiovascular events, such as heart attacks and strokes. This is especially prominent in individuals with pre-existing cardiovascular conditions or those who have previously experienced cardiovascular incidents. The risk is further exacerbated for people living or working near roadways, railyards, seaports, or industrial areas, as they may be exposed to higher levels of particulate matter (PM2.5), a primary component of air pollution.

Particulate matter, or particle pollution, refers to a mixture of solid particles and liquid droplets found in the air. These particles, with diameters less than 2.5 micrometres, can infiltrate the lungs, heart, and other organs, causing adverse effects on the cardiovascular system. Even short-term exposure to fine particulate matter can increase the risk of cardiovascular events, while long-term exposure is associated with a higher risk of mortality and decreased life expectancy.

The biological mechanisms underlying the link between air pollution and cardiovascular issues are complex. One proposed pathway involves the oxidation of low-density lipoprotein (LDL) in the blood, leading to the formation of lipid-rich plaques characteristic of atherosclerosis. The rupture of these advanced plaques can trigger thrombosis, resulting in cardiovascular events such as heart attacks or strokes. Additionally, air pollution has been associated with pro-inflammatory changes in endothelial cells, endothelial dysfunction, and the growth of atherosclerotic lesions, all of which contribute to the increased incidence of cardiovascular diseases.

The impact of air pollution on cardiovascular health is a significant public health issue, with air pollution being recognised as the greatest single environmental health risk. It is estimated that air pollution contributes to several million premature deaths globally each year, with cardiovascular diseases being the leading cause. Governments and organisations worldwide have recognised the urgency of tackling this issue, yet the health effects persist, and air quality levels have shown minimal improvement.

Those with heart and lung conditions are at greater risk

Air pollution is a mix of gases, droplets, and particles that reduce air quality. It can be caused by cars, buses, airplanes, industry, construction, tractors ploughing fields, trucks, and more. Those with heart and lung conditions are at greater risk when it comes to air pollution.

Adults and children with lung or heart conditions are at an increased risk of becoming ill and needing treatment when air pollution levels rise. While only a minority of those with these conditions are likely to be affected, it is not possible to predict who will be affected. For instance, adults and children with asthma may need to increase their use of inhaled reliever medication on days when air pollution levels are higher than average.

Older people are more likely to suffer from heart and lung conditions than younger people, so it is important for them to be aware of current air pollution conditions. On days when the air quality is poor, it is recommended that they limit their time outdoors, especially during peak ozone hours. This is typically between mid-afternoon and early evening.

Ozone is an invisible gas that is created when sunlight triggers a chemical reaction between oxygen-containing molecules and pollution from cars, power plants, factories, and other sources. High levels of ozone can reduce lung function and lead to inflammation and swelling in the airways. This can cause symptoms such as coughing, throat irritation, watery eyes, and chest pain.

In addition to ozone, particulate matter in the air can also pose significant health risks. These fine and coarse particles are released from burning fuel, cars, power plants, and wildfires. They have been linked to a worsening of lung problems, especially asthma, and increased cardiovascular events such as strokes and heart attacks.

To protect themselves from the harmful effects of air pollution, individuals with heart and lung conditions should monitor air quality levels and limit their time outdoors when pollution levels are high. Staying indoors, keeping windows and doors closed, and using air purifiers with HEPA filters can help reduce exposure to pollutants.
