Connection over self-punishment

Dr. Mike Hart interviews Dr. Russell Kennedy about chronic anxiety as a childhood safety adaptation that never turns off, driven more by a body-based "alarm" than by thinking. Kennedy explains why understanding anxiety and talk-based cognitive approaches often have limited effect because subcortical systems communicate through feeling; alarm sensations trigger the mind to generate worries, which can become dopamine-reinforced and addictive. He discusses sensitivity (often cited as 15–20% of the population), modern stressors like smartphones and social media reducing discomfort tolerance, and high-functioning anxiety in high achievers and physicians, with sleep as a key regulation marker. Kennedy emphasizes reconnecting mind and body and adult self with younger self using somatic techniques (body scanning, hand placement, "sensation without explanation," and the SHOULD acronym), notes trauma can occur without an overtly traumatic life, links dysregulated autonomic states to varied symptoms, and shares rapid tools like the physiological sigh and alternate nostril breathing, plus his "Sanity" app and AnxietyMD resources.

Dr. Russell Kennedy is a physician, author, and anxiety expert whose work explores the deeper roots of chronic anxiety, especially the role of childhood stress, nervous system dysregulation, and the body's stored alarm response. In this episode, he explains why anxiety is not just a thinking problem but a feeling problem, how worry becomes a coping pattern that keeps people stuck, why high performers often live in a state of hidden dysregulation, and how self-connection, somatic awareness, and better sleep can help break the cycle. Through a blend of clinical experience, neuroscience, and personal insight, Kennedy helps listeners better understand where anxiety comes from and what it actually takes to heal it at the root.
