In this episode of The Health Edge Mark reviews the neuroscience linking stress and the fight-flight response with chronic complex disease and quality of life. He reviews the research of Richard Davidson PhD, Robert Sapolsky PhD, Herb Benson MD and Bruce McEwen who has advanced the understanding of allostatic load and health. Mark concludes with several lifestyle considerations for creating health that have been shown to reduce allostatic load and the many downstream mediators that undermine health.
