A growing focus on long-term respiratory wellness has elevated the role of pulmonary rehabilitation and preventive care in managing chronic lung diseases. Combining structured exercise, patient education, and behavioral intervention, pulmonary rehabilitation significantly improves functional status, quality of life, and hospital readmission rates in individuals with COPD, interstitial lung disease, and post-COVID fibrosis. Preventive care strategies now emphasize early spirometry, vaccination adherence, and exposure reduction in at-risk populations. Pulmonary Rehabilitation and Preventive Care is also benefiting from community-based delivery models and home-rehab technologies, ensuring access for underserved and mobility-limited patients. Integrating nutritional support, psychological counseling, and smoking cessation programs creates a comprehensive approach that addresses both physiologic and social determinants of respiratory health. Preventive care is no longer peripheral—it's foundational to resilient pulmonary systems and sustainable health outcomes.
