Poor air quality has become a growing concern worldwide, especially in urban areas. For individuals with respiratory conditions—such as asthma, COPD, or seasonal allergies—air pollution can significantly worsen symptoms and decrease quality of life. Understanding the link between air quality and respiratory health is essential for prevention and treatment.
What Is Air Quality?
Air quality refers to the cleanliness of the air we breathe. It’s usually measured by the Air Quality Index (AQI), which monitors pollutants like:
PM2.5 and PM10 (fine particulate matter)
Ozone (O₃)
Nitrogen dioxide (NO₂)
Carbon monoxide (CO)
When AQI levels are high, the air contains more harmful pollutants, which can penetrate deep into the lungs.
How Poor Air Affects the Respiratory System
Poor air quality can:
Trigger asthma attacks
Cause chronic bronchitis
Increase risk of lung infections
Reduce lung function, especially in children and elderly
Even healthy individuals may experience coughing, irritation, or shortness of breath during heavy pollution days.
Who Is Most at Risk？
Children – developing lungs are more sensitive
Elderly – often have weaker respiratory systems
People with pre-existing conditions
Outdoor workers or city residents
What Can You Do?
Monitor AQI daily and stay indoors when levels are high
Use an air purifier indoors, especially at night
Wear a mask during high-pollution days
Use nebulizers if you suffer from respiratory issues – they help deliver medication deep into the lungs when symptoms are triggered by bad air
Protecting your lungs starts with the air you breathe. Stay informed. Stay prepared.
