What happens to your body with constant exposure to pollution?

Air pollution has become a growing concern worldwide, with its levels steadily rising due to urbanisation, industrialisation, and increasing vehicle emissions.
Prolonged exposure to polluted air can lead to many health problems, including respiratory diseases, cardiovascular ailments, and neurological disorders. From chronic bronchitis to lung cancer, the impact of air pollution on our respiratory system is undeniable. Moreover, it can worsen existing heart conditions and increase the risk of heart attacks and strokes. The neurological consequences of air pollution are equally concerning, with studies linking it to cognitive decline, dementia, and other neurodegenerative diseases.
In the following sections, we will delve deeper into the specific ways in which air pollution affects our bodies. We will also explore practical strategies to combat its harmful effects, both indoors and outdoors. By adopting healthy lifestyle habits and taking proactive measures, we can shield ourselves from the silent killer and breathe easier.
Respiratory systemPollution harms the lungs and airways. Fine particles (PM2.5) and other pollutants can cause inflammation, reduce lung capacity, and worsen conditions like asthma and bronchitis. Prolonged exposure increases the risk of lung cancer, especially for vulnerable groups like children and the elderly.
Cardiovascular systemAir pollution also damages the heart. Pollutants like PM2.5 and nitrogen dioxide enter the bloodstream, causing inflammation and damaging blood vessels. This increases the risk of heart disease, heart attacks, and strokes. It can also raise blood pressure and lead to plaque buildup in arteries.
Neurological systemPollution can impact brain health. Long-term exposure may impair brain function and increase the risk of neurodegenerative diseases like Alzheimer’s and Parkinson’s. Pollutants cause oxidative stress and inflammation in the brain, which affects cognitive function and accelerates ageing.
Other health issuesBesides impacting the respiratory, cardiovascular, and nervous systems, pollution can cause skin rashes, eye irritation, and dryness. Long-term exposure can also weaken the immune system, making individuals more prone to infections and illnesses.

Indoor air quality
Improving indoor air quality is one of the first steps toward protecting yourself from pollution. Ensuring proper ventilation in your home can help reduce the buildup of indoor pollutants. Air purifiers with HEPA filters can capture harmful particles in the air, providing cleaner and healthier air to breathe. Additionally, it’s important to avoid common indoor pollutants such as harsh cleaning products, tobacco smoke, and mould. Regular cleaning and maintaining a humidity level between 30-50% can further reduce indoor air contaminants.

Outdoor precautions
When it comes to outdoor activities, timing is essential. Air pollution levels tend to be lower early in the morning or late in the evening, making these ideal times for outdoor exercise. Using air quality apps can help monitor pollution levels in real time, allowing you to make informed decisions. Wearing a mask designed to filter out pollutants can also protect you during high-pollution days. Avoiding known pollution hotspots, such as congested roads and industrial areas, can further minimize exposure.

Healthy lifestyle habits
Maintaining a healthy lifestyle can help mitigate the adverse effects of pollution on the body. Regular exercise boosts lung capacity and helps maintain cardiovascular health, which is crucial in polluted environments. A balanced diet rich in antioxidants can help combat oxidative stress caused by pollution. Getting adequate sleep allows the body to repair and regenerate, while stress management techniques, such as meditation or yoga, help reduce inflammation in the body.
In summary, air pollution is a significant threat to human health, affecting the respiratory, cardiovascular, and neurological systems. To protect yourself, it is essential to focus on both indoor and outdoor air quality, adopt healthy habits, and stay informed about pollution levels. Taking proactive measures can help safeguard your well-being and promote a healthier lifestyle in a polluted world.
