Air pollution can have a significant impact on respiratory health. Long-term exposure to polluted air, fine particulate matter, smoke, industrial emissions, and harmful gases can irritate the airways and lungs and may contribute to respiratory diseases. People with existing lung conditions may experience worsening symptoms during periods of poor air quality.

Common Respiratory Problems

• Asthma and worsening of asthma symptoms
• Chronic bronchitis
• Chronic obstructive pulmonary disease (COPD)
• Recurrent respiratory infections
• Reduced lung function
• Airway inflammation and irritation
• Worsening of existing lung diseases

Common Symptoms

• Persistent or recurring cough
• Shortness of breath
• Wheezing
• Chest tightness or discomfort
• Throat and nose irritation
• Excess mucus production
• Fatigue and reduced exercise tolerance

Sources of Air Pollution

Air pollution can come from vehicle emissions, industrial activities, construction dust, biomass and waste burning, cigarette smoke, household pollutants, and other environmental sources. Fine particulate matter such as PM2.5 can penetrate deep into the lungs and may have significant effects on respiratory health.

Diagnosis

Evaluation depends on the symptoms and the individual's exposure history. A healthcare professional may perform a physical examination and recommend tests such as chest X-rays, lung function testing, oxygen measurement, or other investigations to identify the underlying respiratory condition.

Treatment and Management

Treatment depends on the specific respiratory condition and its severity. It may include inhaled medications, medicines to control inflammation, treatment of respiratory infections, oxygen therapy when required, and pulmonary rehabilitation. Reducing exposure to polluted air is an important part of long-term respiratory care.

Prevention and Protection

• Check local air-quality levels when pollution is high
• Limit prolonged outdoor activity during periods of poor air quality
• Avoid cigarette smoke and indoor sources of pollution
• Improve indoor ventilation and reduce household pollutants
• Use appropriate respiratory protection when exposure cannot be avoided
• Keep asthma and other chronic lung conditions properly controlled
• Follow prescribed medications and regular medical check-ups

When to Seek Medical Attention

Consult a healthcare professional if you experience persistent cough, recurring wheezing, unexplained breathlessness, chest tightness, or a noticeable decline in exercise tolerance. Severe or sudden difficulty breathing requires urgent medical evaluation.
