In 1905, the Yogi Publication Society published Yogi Ramacharaka's 'Science of Breath', which to this day remains one of his most popular and respected works. 100 years later, Stephen Elliott, accomplished student of Eastern yogic and martial arts, engineer, inventor, and life scientist, asserts a 'New Science of Breath'. With it, Elliott offers us a revolutionary new theory of health based on breathing for autonomic nervous system balance, autonomic nervous function underlying all aspects of health and well being - body, mind, and spirit. Importantly, this 'new science' sheds a light of hope on today's pandemic health challenges ranging from stress, anxiety, and chronic muscle tension, to hypertension and attention deficit disorder. The emerging medical understanding is that these conditions are rooted in autonomic nervous system imbalance - what has not been understood is the root cause of this imbalance. Elliott posits that the root cause is in fact suboptimal breathing. The New Science of Breath introduces 'Coherent Breathing', a specific breathing modality that promotes autonomic nervous system balance and cardiopulmonary resonance. Autonomic balance yields peace of mind, well being, and enhanced biological function. The therapeutic efficacy of Coherent Breathing is supported by the work of integrative neurotherapist Dee Edmonson, RN, Fellow BCIA - EEG. Dee presents a dozen compelling case observations where Coherent Breathing was applied adjunctively with conventional forms of neurotherapy, all with profoundly positive result. This book is must reading for health care professionals, educated health enthusiasts, and serious athletes. For yoga and meditation enthusiasts, when combined with relaxation and stillness, Coherent Breathing directly results in meditation.
