 “practicing yoga is one of the best things you can do for the health of your lungs. Yoga will strengthen the muscles of your chest, increase your lung capacity and boost oxygen intake.” – Tania Tarafdar

 

Chronic obstructive pulmonary diseases (COPD) are progressive lung diseases that obstruct airflow. The two main types of COPD are chronic bronchitis and emphysema. COPD is very serious being the third leading cause of death in the United States, over 140,000 deaths per year and the number of people dying from COPD is growing. More than 11 million people have been diagnosed with COPD, but an estimated 24 million may have the disease without even knowing it. COPD causes serious long-term disability and early death. Symptoms develop slowly. Over time, COPD can interfere with the performance of routine tasks and is thus a major cause of disability in the United States. The most common cause of COPD is smoking. But, COPD also occurs with miners and is called black lung disease. COPD is not contagious. Most of the time, treatment can ease symptoms and slow progression.

 

There is no cure for COPD. COPD treatments include lifestyle changes, medicine, bronchodilators, steroids, pulmonary rehabilitation, oxygen therapy, and surgery. They all attempt to relieve symptoms, slow the progress of the disease, improve exercise tolerance, prevent and treat complications, and improve overall health. Yoga practice would seem to be a useful lifestyle change that could improve COPD symptoms as it has been shown to improve exercise tolerance and overall health and includes breathing exercises. Indeed, it has been shown that yoga practice improves the mental and physical health of patients with COPD.

Ranjita and colleagues studied the effectiveness of yoga practice on Chronic obstructive pulmonary diseases (COPD) by recruiting non-smoking male coal miners with COPD and randomly assigned them to a treatment as usual group or a yoga practice group. Yoga was practiced in 90-minute session, 6 days per week for 12 weeks. Before and after training the participants were measured for exercise tolerance with a walking test, breathing difficulty, blood oxygen levels, pulse rate, and fatigue.

 

They found that the miners who participated in the yoga practice had a significant (24.4%) improvement in breathing, a 25.9% decrease in fatigue, a 19.9% increase in the walking test distance covered, a 1.3% increase in blood oxygen levels, and a 4.3% decrease in resting pulse rate. Hence, yoga practice significantly improved the miners’ lung function, energy level, and physical fitness.

 

These are excellent results and suggest that yoga practice may be a very useful additional treatment for Chronic obstructive pulmonary diseases (COPD). Previous research has shown that yoga practice improved overall health, depression, anxiety in COPD sufferers. Since, yoga practice is a gentle exercise that includes breathing exercises, it seems reasonable that it would have these beneficial effects for COPD sufferers. It would be useful if future research compared yoga practice to other forms of exercise as treatments for COPD. The yoga practice used in this study was exceptionally intensive. Many patients would not be willing to engage in such an intense practice. Future research should also look at whether less intensive yoga practice might be beneficial.

 

So, improve chronic obstructive pulmonary diseases (COPD) with yoga.

 

“A comprehensive yoga program can have a salutary effect on general health and respiratory health and thereby help increase a person’s ability to perform activities of daily living. COPD is known to increase the level of stress, emotional vulnerability, inactivity and muscle wasting. Yoga techniques are particularly suited for promoting relaxation, psycho-emotional stability and exercise tolerance.” – Vijai Sharma

Study Summary

Ranjita, R., Hankey, A., Nagendra, H. R., & Mohanty, S. (2016). Yoga-based pulmonary rehabilitation for the management of dyspnea in coal miners with chronic obstructive pulmonary disease: A randomized controlled trial. Journal of Ayurveda and Integrative Medicine, 7(3), 158–166. http://doi.org/10.1016/j.jaim.2015.12.001

 

Abstract

Background: Coal mine dust exposure causes chronic airflow limitation in coal miners resulting in dyspnea, fatigue, and eventually chronic obstructive pulmonary disease (COPD). Yoga can alleviate dyspnea in COPD by improving ventilatory mechanics, reducing central neural drive, and partially restoring neuromechanical coupling of the respiratory system.

Objectives: To evaluate the effectiveness of Integrated Approach of Yoga Therapy (IAYT) in the management of dyspnea and fatigue in coal miners with COPD.

Materials and methods: Randomized, waitlist controlled, single-blind clinical trial. Eighty-one coal miners (36–60 years) with stable Stages II and III COPD were recruited. The yoga group received an IAYT module for COPD that included asanas, loosening exercises, breathing practices, pranayama, cyclic meditation, yogic counseling and lectures 90 min/day, 6 days/week for 12 weeks. Measurements of dyspnea and fatigue on the Borg scale, exercise capacity by the 6 min walk test, peripheral capillary oxygen saturation (SpO2%), and pulse rate (PR) using pulse oximetry were made before and after the intervention.

Results: Statistically significant within group reductions in dyspnea (P < 0.001), fatigue (P < 0.001) scores, PR (P < 0.001), and significant improvements in SpO2% (P < 0.001) and 6 min walk distance (P < 0.001) were observed in the yoga group; all except the last were significant compared to controls (P < 0.001).

Conclusions: Findings indicate that IAYT benefits coal miners with COPD, reducing dyspnea; fatigue and PR, and improving functional performance and peripheral capillary SpO2%. Yoga can now be included as an adjunct to conventional therapy for pulmonary rehabilitation programs for COPD patients.

Relax with Slower Breathing with Meditation

“We often assume breathing is just a natural skill; everyone knows how to inhale and exhale. But breathing is a miracle. Being aware of our breath not only helps us manage the difficulties in everyday life, it also helps develop our wisdom and compassion. We can sit and breathe, but it is just as important to practice mindful breathing while we are moving. Life is a path, but life is not about getting to a certain place.” – Thich Nhat Hanh

 

Breathing is essential for life and generally occurs automatically. It’s easy to take for granted as it’s been there our entire lives. Nevertheless, we become more aware of it when it varies with circumstances, such as when we exercise and also in emotional states, especially fear and anxiety. But we rarely notice it during everyday ongoing life. Yet, its characteristics are associated with our state of well-being. Slow deep breathing is characteristic of a healthy relaxed state.

 

Meditators have been trained to pay attention to and even focus on breathing. Meditation produces a relaxed state and during meditation, respiration slows and deepens. Meditation also, promotes health and well-being. All this would predict that meditation practice would result in slower deeper breathing in the individual even when they are not meditating. In today’s Research News article “Long-term mindfulness training is associated with reliable differences in resting respiration rate.” See:

Wielgosz and colleagues examine this question. They compared the resting respiration rates of long-term meditators to a matched group of non-meditators and found that the meditators had significantly lower respiration rates (11%) than the controls. They further explored the lower respiration rates in meditators and found that it was significantly related to the total number of hours that these practitioners had spent on meditation retreats and not to the hours spent in daily practice.

 

These are interesting results that suggest that long-term meditation practice that includes meditation retreats is associated with lower respiration rates. These lower rates, in turn, suggest that there was an improvement in the overall well-being of the practitioners. Meditation retreats allow for extended periods of calm and quiet that are unavailable during everyday life with all its demands and stressors. It is possible that these extended periods are necessary to have an overall sustained reduction in respiration rates and the suggested improvement in overall well-being. This clearly suggests that including retreats in a meditation practice is very important.

 

It needs to be kept in mind that causation cannot be determined in this study. It is possible that people who engage in long-term meditation and attend meditation retreats are characteristically calmer people who had lower respiration rates even before initiating meditation practice. It will require a study where baselines are established before a meditation practice is commenced and then randomly assigning volunteers to either meditation practice with or without retreats or to a no-meditation condition.

 

Regardless, relax with slower breathing with meditation.

 

“Our breathing is a stable solid ground that we can take refuge in. Regardless of our internal weather- our thoughts, emotions and perceptions- our breathing is always with us like a faithful friend. Whenever we feel carried away, or sunken in a deep emotion, or scattered in worries and projects, we return to our breathing to collect and anchor our mind.” – Plum Village

Study Summary

Wielgosz, J., Schuyler, B. S., Lutz, A., & Davidson, R. J. (2016). Long-term mindfulness training is associated with reliable differences in resting respiration rate. Scientific Reports, 6, 27533. http://doi.org/10.1038/srep27533

 

Abstract

Respiration rate is known to correlate with aspects of psychological well-being, and attention to respiration is a central component of mindfulness meditation training. Both traditional contemplative systems and recent empirical evidence support an association between formal mindfulness practice and decreased respiration rate. However, the question of whether long-term mindfulness training is associated with stable, generalized changes in respiration has yet to be directly investigated. We analyzed respiration patterns across multiple time points, separated by two months or more, in a group of long-term mindfulness meditation practitioners (LTMs, n = 31) and a matched group of non-meditators (Controls, n = 38). On average, LTMs showed slower baseline respiration rate (RR) than Controls. Among LTMs, greater practice experience was associated with slower RR, independently of age and gender. Furthermore, this association was specific to intensive retreat practice, and was not seen for routine daily practice. Full days of meditation practice did not produce detectable changes in baseline RR, suggesting distal rather than immediate effects. All effects were independent of physiological characteristics including height, weight, body-mass index and waist-hip ratio. We discuss implications for continued study of the long-term effects of mindfulness training on health and well-being.
