Yoga: unraveling the internal pharmacy – Impact on genome and epigenome

Abstract

Complex and chronic lifestyle disorders have become the leading cause of death and disability worldwide. They involve multiple morbidities necessitating the attention of numerous healthcare facilities as well as community-based care too. Stress and anxiety brought on by the fast-paced life, unhealthy eating habits, sedentary lifestyle, poor quality of life, polypharmacy, and high medical costs have significantly influenced the development of such multimorbid conditions. Most chronic complex diseases share a similar underlying pathology including high levels of stress, inflammatory immune response, persistent activation of the hypothalamo-pituitary-adrenal axis, oxidative stress, accelerated immune-aging, dysregulated blood flow, enhanced apoptosis and accelerated aging with shorter telomeres and DNA damage. These are modifiable factors which can impact disease progression and no single treatment modality in modern medicine can alone impact all these factors. As a result, the treatment must involve an integrated approach that targets both mind and body and each of these factors which form an architectural framework which supports the onset of these complex lifestyle disease and thus though we may enjoy longer lifespan, but it is accompanied by shorter health span. Yoga, a mind-body intervention with Indian roots, strives to bring about the synchronization of physical and mental health by unraveling and switching on the internal pharmacy and maintenance of homeostasis at cellular and molecular level.
