Sometimes we fall prey to illness despite following the most conscientious lifestyle. Yoga can help us by improving and balancing our basic defense against illness – the immune system. Yoga postures, pranayama, relaxation and meditation are all powerful tools for helping to stimulate or calm the immune system. How yoga works is by lowering stress hormones that weaken the immune system and, at the same time, strengthening the respiratory organs, lymphatic system and overall circulation. Regular yoga practice is very good medicine!
