A radically new way of thinking about mental health. What really causes depression and anxiety - and how can we really solve them? Award-winning journalist Johann Hari suffered from depression since he was a child and started taking anti-depressants when he was a teenager. He was told that his problems were caused by a chemical imbalance in his brain. As an adult, trained in the social sciences, he began to investigate whether this was true - and he learned that almost everything we have been told about depression and anxiety is wrong.
Across the world, Hari found social scientists who were uncovering evidence that depression and anxiety are largely caused by key problems with the way we live today. Hari's journey took him from a mind-blowing series of experiments in Baltimore, to an Amish community in Indiana, to an uprising in Berlin. Once he had uncovered nine real causes of depression and anxiety, they led him to scientists who are discovering seven very different solutions - ones that work.
