New Delhi : The World Health Organization’s November 2024 report revealed that chronic obstructive pulmonary disease (COPD) remains the fourth leading cause of death worldwide. The condition was responsible for an estimated 3.5 million deaths in 2021 according to the latest available global data. COPD is a common and serious lung disease, and the WHO noted that smoking, indoor and outdoor pollution, and harmful inhalants are among its most significant triggers.
Children, too, are increasingly at risk due to high pollution levels, secondhand smoke and early-life respiratory infections. With winter pollution worsening across many Indian cities, especially Delhi NCR, experts say this is the right moment to revisit how COPD can be prevented through everyday habits and early interventions.
What COPD Really Is
COPD is identified as a chronic lung disorder that results in persistent breathlessness, chronic cough and long-term mucus production. According to the pulmonologist, the disease is a major global health burden linked to high levels of mortality and long-term disability across populations.
The condition develops slowly and often goes unnoticed in its early stages. Over time, narrowed airways and irreversible lung damage make breathing progressively more difficult. The pulmonologist explained that the air people breathe plays a crucial role in determining long-term lung health, especially for those living in severely polluted areas.
Why COPD Happens
COPD is primarily caused by the inhalation of harmful particles and gases. These include cigarette smoke, secondhand smoke, indoor pollution from biomass fuel, outdoor smog, chemicals, dust and repeated lung infections. The pulmonologist added that a small percentage of COPD cases are due to a rare genetic condition known as alpha-1 antitrypsin deficiency. In such cases, checking family history becomes important for early detection.
Preventing COPD: What Experts Recommend
Preventing COPD requires a comprehensive and consistent lifestyle strategy. While quitting smoking remains the single most effective step for protecting the lungs, the pulmonologist stressed that prevention goes far beyond just avoiding cigarettes. Clean air, healthy food, ideal body weight and regular vaccinations all play a key role.
The pulmonologist shared nine essential tips that can help significantly reduce the risk of COPD, particularly for people living in high-pollution regions such as Delhi NCR.
9 Essential Tips to Prevent COPD
- Avoid smoking completely and seek medical support to quit if necessary.
- Avoid secondhand smoke and maintain distance from people who smoke.
- Reduce indoor pollution by switching from biomass fuels to LPG, keeping windows open for ventilation and using air purifiers when required.
- Limit exposure to outdoor pollution. Wear a mask during high pollution days and stay indoors when air quality is poor. Consider shifting residence or workplace if the area remains persistently polluted.
- Use proper protective gear, including masks, if your profession involves dust, chemicals or industrial fumes.
- Avoid exposure to strong or irritating smells that can trigger respiratory issues.
- Maintain healthy lifestyle practices such as regular exercise and a balanced diet.
- Keep body weight within a healthy BMI range because excess weight worsens breathing and being underweight can increase vulnerability to more severe COPD.
- Ask a doctor about preventive vaccinations such as influenza and pneumococcal shots when appropriate.
