After decades in practice, Linus began questioning many of the assumptions underlying modern psychiatry, leading him to investigate how hormones, metabolism, inflammation, circadian biology, and the endocrine system shape mood and cognition. Together, Peter and Linus examine why psychiatric care should aim not only to reduce symptoms but also to restore the full human experience. They discuss how psychiatric medications work, where they fall short, and why distinguishing bipolar disorder from unipolar depression is essential for effective treatment. The conversation also explores the growing mental health burden of social isolationn associated with digital devices and social media, along with the biological factors—nutrition, exercise, sleep, and chronic stress—that influence resilience and distress tolerance. Linus explains the powerful roles of estrogen, progesterone, testosterone, and thyroid hormone in regulating mood and cognition across the lifespan. Finally, Peter and Linus review the promise and limitations of ketamine and psychedelic therapies, and why the future of psychiatry may lie in integrating neuroscience, endocrinology, and whole-body physiology to better understand, diagnose, and treat mental illness.
