Today, Kati sits down with neuroscientist Dr. Ben Rein, to dive into the social connection and the growing loneliness epidemic. Dr. Rein, author of Why Brains Need Friends, explains how your brain is fundamentally wired for interaction, why isolation is a biological stressor, and what you can do to improve your social health. In this must-watch episode, Dr. Rein explains the mechanical changes happening in your brain during isolation and clarifies why the U.S. Surgeon General has declared a loneliness epidemic. You'll learn the surprising truth about isolation and physical health—it can cause stress hormones like cortisol to rise within days and is associated with more adverse health outcomes. Dr. Rein also reveals the science behind why isolation can make people more irritable and even angry, linking it to the body's natural stress response. Kati and Dr. Rein discuss the difference between in-person and digital interactions, noting that less "lifelike" communication strips away vital social cues like eye contact, body language, and even smell, leading to fewer mood benefits. Dr. Rein introduces the concept of a "Social Diet" and social journaling—practical tools to help you identify which interactions energize you ("breath in" relationships) versus those that leave you depleted. The conversation takes fascinating turns into the role of brain chemicals like oxytocin and serotonin in social reward and the development of empathy. Plus, discover the incredible, innate ability of dogs to detect physiological stress signals and the science of how pets help children develop crucial social skills.
