NEW DELHI, INDIA, May 2, 2007: A study conducted by researchers at the Washington State University has found that the immunity system of breast cancer survivors improved significantly after practicing the Iyengar form of yoga. Created by B.K.S. Iyengar, based on the traditional eight limbs of yoga as expounded by Pantajali in his Yoga Sutras, this yoga form emphasizes the development of strength, stamina, flexibility and balance, as well as concentration and meditation. Considered to be a more active form of yoga, researchers reported on Monday at the American Physiological Society meeting in Washington DC that in breast cancer survivors, the Iyengar method not only promoted psychological well-being but also benefited the patient’s immune system. According to lead researcher Pamela E. Schultz, practicing the yoga form resulted in decreased activation of an important immune system protein called NF-kB in patients, which is a mark of stress in the body. “So it’s possible that decreased activation of NF-kB indicates decreased stress in the body. NF-kB is activated in the body by physical or mental stress,” said Schultz.
Speaking to Times of India, 89-year-old Iyengar said, “Similar studies in Mumbai found that certain asanas improve the quality of blood and results in better blood circulation. It also improved the production of proteins in the immune system called T-cell receptors that actually direct the immune system to attack specific targets. Immune cells that contain the engineered T-cell receptor better display targeted immunity with a few asanas.” Cancer and its treatments are associated with considerable distress, impaired quality of life and reduced physical function, especially for women with breast cancer who receive multi-modality treatment over an extended period of time. “Yoga greatly helps to relieve and improve quality of life among cancer patients over time,” Iyengar said. Dr. Chidanand Murthy, director of Central Council for Research in Yoga, said, “A similar study conducted in AIIMS on 30 patients in 2006 found that Sudarshan Kriya and Pranayama greatly helped cut down the growth of breast cancer cells within the body. Through release of stress, adverse effects of chemotherapy were also avoided.”
