Loneliness isn't just an emotional state—it can physically alter the brain. In this episode of Mind Theory, we explore the surprising ways that prolonged social isolation affects brain function, from increasing stress to shrinking parts of the brain that regulate emotions and cognition. We'll also dive into the concept of social pain and why rejection can hurt as much as physical injury. As the global experience of loneliness rises, understanding its neurological impact has never been more important. Join us as we uncover the science behind loneliness and what it means for our mental and physical health.
