Chronic Obstructive Pulmonary Disease (COPD) is a progressive respiratory condition characterized by airflow limitation, dyspnea, and systemic manifestations that significantly impair quality of life (QoL). Beyond pharmacological treatments, non-pharmacological and mind–body interventions have emerged as essential components of holistic COPD management. Deep breathing exercises, encompassing diaphragmatic and pursed-lip breathing, are simple yet powerful techniques that enhance respiratory efficiency, reduce dyspnea, and alleviate psychological distress. This article explores the integration of deep breathing as a mind–body practice in COPD management, its physiological and psychological mechanisms, evidence-based outcomes, and nursing implications for practice. Findings from contemporary research underscore that deep breathing improves pulmonary parameters, enhances relaxation, reduces anxiety, and fosters a greater sense of control among COPD patients.
