Johann Hari

Journalist and writer Johann Hari says depression and anxiety are not caused by chemical imbalances in our brain but by the way we live today.

Hari has suffered from depression since he was a child and was told it was caused by chemical imbalance. As an adult he began to investigate whether that was true and discovered that scientists across the world were uncovering evidence to say it was not. His investigation led him to define nine real causes of depression and to find scientists who said they had discovered seven solutions that work.

Hari has written for papers including The Independent and Huffington Post. He is also author of Chasing the Scream: The First and Last Days of the War on Drugs.
