This Substack unpacks how horses—through the EquiLateral™ EMDR protocol—help trauma survivors reclaim a sense of safety in their own bodies. Drawing on Polyvagal Theory and insights from 20 participants with stress-related disorders, it explores the horse’s calm presence as more than comforting—it’s a potent biological signal that helps shift the nervous system from defense to connection. In that space, within the “window of tolerance,” deep trauma processing becomes possible, and healing takes root.
