Brian interviews Thomas R. Verny, M.D. Thomas is a clinical psychiatrist, academic, and author of eight books, including The Secret Life of the Unborn Child, and The Embodied Mind: Understanding the Mysteries of Cellular Memory, Consciousness, and Our Bodies. He has taught at Harvard University, University of Toronto, York University (Toronto), and St. Mary’s University of Minnesota. Thomas Verny talks about how can loneliness affect your health. Perceived social isolation negatively impacts the physical health of both humans and animals, leading to the activation of the hypothalamic–pituitary–adrenal (HPA) axis, the body’s response to stress, and an increase in depressive behaviours. Social isolation and socioeconomic stress have been associated with enhanced inflammation and an impaired immune response.
