People who have been through one or more "adverse childhood experiences" have not only poor mental health outcomes, but also higher incidence of heart disease, diabetes and even some cancers. Those experiences might include such things as physical, emotional and sexual abuse. Since the effects of trauma can be physical, "body-mind" interventions, like yoga, may be able to uniquely address them. Regulated breathing, for example, calms the parasympathetic nervous system. Practicing staying in the moment counteracts some of the dissociative effects of trauma. And the physical activity of yoga, of course, can directly improve health.
