Background: Determining if diaphragmatic breathing exercises enhance pulmonary function in smokers was the goal of this narrative review. Further research is necessary, though, to fully understand how diaphragmatic breathing affects a smoker's lungs. Methods: To find the most recent data on the impact of diaphragmatic breathing exercises on smokers' pulmonary functioning, the author searched PubMed and Google Scholar. Results: The original articles included in this review were randomly selected from systematic reviews. In patients with chronic obstructive pulmonary disease (COPD), diaphragmatic breathing appears to be helpful, suggesting roving exercise capacity and respiratory performance. Conclusions: This narrative review found that the poor quality of research made it difficult to determine exactly how effective diaphragmatic breathing is in clinical use. However, it might be a doable and useful therapeutic strategy for various disorders.
