Chronic Obstructive Pulmonary Disease (COPD) is a challenging condition, often accompanied by heightened levels of depression and anxiety among patients. In the pursuit of holistic approaches to managing COPD, researchers have turned to yoga as a potential solution. While the physical and mental benefits of yoga are well-documented, its impact on lung function, specifically diffusion capacity, has been less explored. To fill this knowledge gap, a controlled trial was conducted by Ritu Soni, et. al., (2012) shedding light on the potential benefits of yoga for COPD patients.

The study involved 60 participants with mild-to-moderate COPD, aged between 30 to 60 years, and of both genders. These patients were drawn from Guru Teg Bahadur Hospital in Delhi and were divided into two groups: a control group receiving conventional drug therapy and a yoga group. Both groups continued with their usual medical treatment. However, members of the yoga group received additional intervention.

Over the course of 21 days, patients in the yoga group were directed to the cardiopulmonary laboratory, where a yoga instructor guided them through daily sessions involving pranayama (breathing exercises) and various yoga postures. Following this initial period, participants were encouraged to continue practicing yoga at home for 45 minutes each morning for the next two months.

To measure the impact of yoga on lung function, the researchers utilized a computerized Medisoft instrument (HYPAIR compact) to assess diffusion capacity in both groups before and after the two-month intervention.

The results of the study were promising. Statistical analysis revealed a significant improvement in the Transfer Factor of Lung for Carbon Monoxide (TLCO) among the yoga group. In patients with mild COPD, TLCO increased from 17.61 ± 4.55 to 19.08 ± 5.09 ml/mmHg/min. In those with moderate COPD, TLCO increased from 14.99 ± 4.02 to 17.35 ± 3.97 ml/mmHg/min.

In conclusion, this study highlights the positive impact of yogic breathing exercises on diffusion capacity in COPD patients. Yoga, when incorporated into the treatment regimen alongside conventional medical therapy, can offer tangible benefits to individuals with COPD. This research opens the door to the use of yoga as an adjunct therapy in the management of COPD, offering a potential avenue for enhancing the well-being and lung function of affected individuals. Further exploration and validation of these findings could provide valuable insights into optimizing COPD care.
