Around one billion people worldwide suffer from stress-related illnesses. This trend is on the rise. What protects those who remain healthy? Is their resilience innate? Or can they learn to cope with chronic stress and crises? This report embarks on a journey to meet leading figures in resilience research, interviewing experts in epigenetics and neuroscience. At Europe's largest resilience center in Mainz, researchers are conducting a long-term study to discover the mechanisms people use to maintain mental health despite stress and crises. In the south of France, they meet with Boris Cyrulnik, a pioneer in resilience research. His credo: it's not just individuals who must take responsibility for developing their resilience; society and politics must also create living conditions that foster stable mental health. We also tell the moving story of two families united by tragedy: after the violent deaths of their two sons, who were friends, they struggle to find their way back to life. Our experiences, our environment, and our genes: everything influences our mental resilience. Resilience is not a magic word or a promise of happiness, but a lifelong learning process. #dwdocumentary #documentary #mentalhealth DW Documentary brings you information beyond the headlines.
