Lifestyle Strategies for Symptom Relief and Disease Progression Control in Interstitial Lung Disease: A Comprehensive Review

Background: Interstitial lung diseases (ILD) represent a heterogeneous group of pulmonary disorders characterized by progressive fibrosis and inflammation of the lung parenchyma. While pharmacological interventions remain the cornerstone of treatment, lifestyle modifications play an increasingly recognized role in symptom management and potentially slowing disease progression. Objective: This review synthesizes current evidence on lifestyle strategies that can improve quality of life, reduce symptom burden, and potentially influence disease trajectory in ILD patients. Methods: A comprehensive literature review was conducted examining peer-reviewed studies, clinical guidelines, and expert consensus statements published between 2015 and 2025 focusing on non-pharmacological lifestyle interventions in ILD management. Results: Key lifestyle strategies with evidence-based support include pulmonary rehabilitation programs, nutritional optimization, smoking cessation, environmental exposure avoidance, sleep hygiene, stress management, and vaccination protocols. These interventions demonstrate potential for symptom improvement, functional capacity enhancement, and quality of life benefits. Conclusions: A multifaceted approach incorporating evidence-based lifestyle modifications alongside standard medical care offers the best prospects for comprehensive ILD management. Further research is needed to establish optimal implementation protocols and long-term outcomes.
