On World Lung Day 2025, health experts warn that women are facing a disproportionately higher risk of lung damage even if they have never smoked. This emerging concern highlights how environmental and biological factors are causing serious lung health issues among women, challenging the traditional notion that lung diseases mainly affect smokers. Doctors emphasize that polluted air, second-hand smoke, and indoor cooking fuels contribute significantly to lung damage, especially in women living in both rural and urban environments across India and globally.
Key Developments and Findings
Recent studies and clinical observations reveal that women are more likely than men to develop chronic lung conditions such as chronic obstructive pulmonary disease (COPD), despite lower rates of smoking. A large U.S.-based study analyzing data from over 23,000 adults aged 40 and above found that women had nearly 50% higher odds of developing COPD compared to men, even among non-smokers where women were 62% more likely to have the disease. This suggests factors beyond smoking, possibly including air pollution exposure and genetic susceptibility.
In India, women, particularly rural homemakers, are exposed to indoor air pollution from traditional cooking methods using wood, coal, or cow dung, which can be as harmful as smoking several cigarettes daily, says Dr. Sushrut Ganpule, Consultant – Chest Medicine at Jupiter Hospital. Urban women are also exposed to traffic pollution and passive smoke in workplaces and homes, which silently deteriorate lung health, leading to higher cases of chronic cough, asthma, and early onset COPD.Expert Opinions and Context
Dr. Manav highlights the connection between lung health and mental well-being, explaining that respiratory difficulties such as breathlessness and poor sleep can significantly impact confidence and emotional health, thus treatment approaches must encompass both. Meanwhile, Dr. Aakaar Kapoor, CEO & Lead Medical Advisor at City X-Ray & Scan Clinic, points out that lung diseases often remain undiagnosed in early stages due to symptoms like long-lasting cough or fatigue being wrongly attributed to aging or general weakness, resulting in advanced disease at diagnosis.
Globally, research led by NIH scientists shows that lung cancer among non-smokers—most commonly women—is linked to environmental factors, including fine-particle air pollution causing genetic mutations similar to those found in smokers’ lung cancer tumors. Studies focused on Asian American and Pacific Islander women indicate higher susceptibility to lung cancer, probably due to genetic predispositions combined with exposure to secondhand smoke and air pollution. This finding reflects a broader pattern, with approximately 10-20% of lung cancer cases worldwide now occurring in never-smokers, many of them women.
Public Health Implications
These findings underline the urgent need for expanded public health strategies that go beyond tobacco control to reduce lung disease burden in women. Reducing exposure to indoor and outdoor air pollution, improving ventilation in homes, limiting second-hand smoke, and raising awareness about early respiratory symptoms are crucial measures. Physicians also stress the importance of early screening and diagnosis, particularly in non-smoking women who may be overlooked by traditional risk assessment models focusing mainly on smokers.
Potential Limitations and Balanced View
While observational studies highlight gender disparities in lung disease risk, limitations include reliance on self-reported smoking histories and incomplete data on hormonal, genetic, and occupational factors influencing susceptibility. Researchers argue more detailed studies are needed to unravel the complex interactions behind these risks and to tailor preventive and therapeutic interventions accordingly. Despite challenges, the consensus is clear that lung health in women deserves heightened clinical and public health attention.
Practical Takeaways for Readers
For everyday health decisions, individuals should minimize exposure to indoor cooking smoke by using cleaner fuels or improved ventilation, avoid passive tobacco smoke, and seek medical evaluation for persistent respiratory symptoms such as chronic cough or breathlessness. Maintaining lung health through regular exercise, healthy nutrition, and avoiding pollutants aligns with broader wellness goals. Clinicians are encouraged to consider gender-specific risks in diagnosis and management of lung diseases.
