yoga for cancer treatment

The preliminary results of a recent study, the largest ever multi-centre randomised trial on ‘cardiac rehabilitation and health benefits of yoga’, have revealed that yoga is safe, and offers ‘similar’ benefits as cardiac care that is typically prescribed after surgery.

The study was done in 24 centres across India, and about 4000 patients who were discharged following a heart attack, were monitored. The patients were randomized to undergo a structured ‘Yoga Care’ programme that included meditation, breathing exercises and selective heart-friendly yoga poses, apart from lifestyle advice. The control group were just given conventional lifestyle advice.

Cardiac rehabilitation is usually prescribed for patients following a heart attack and cardiac surgery, to get them back to normal activities. The study lasted for five years, and ended in September 2018.

Funded by the Indian Council for Medical Research (ICMR) and the Medical Research Council, UK, the results were presented at the meeting of American Heart Association in Chicago last month.

The prevalence of ischemic heart disease in India has grown by more than 50 percent, from 10 million in 1990 to 24 million in 2016. The trial is the largest so far in yoga and cardiac rehabilitation, and has shown that yoga can be an alternative to conventional cardiac rehabilitation programmes. It also meets the needs of cardiac rehabilitation for patients falling into the low income and middle income brackets.

Patients who attended at least 75% of the sessions received the benefits. The results indicate that yoga is safe, comparatively inexpensive and does not require any elaborate infrastructure. It is culturally acceptable and improves quality of life. In fact, independent doctors say that there is also scientific evidence that suggests yoga as being equivalent to conventional cardiac rehabilitation. According to experts, this trial transcends yoga from belief to science-based intervention.

Most people now go on to survive a heart attack, and hence, they can readjust better after such a catastrophic event and make maximum contributions to the society. This is particularly true in India, where heart attacks are seen occurring at a young age, says Prof. Sanjay Kinra, Head, Epidermiology, London School of Hygiene and Tropical Medicine.

In recent times, yoga has gained good popularity nationally and internationally as a tool for health promotion, with the United Nations having declared 21st June as International Yoga Day.
