Solitary confinement is a form of torture that undermines identity and mental health. In “The Truth About Mental Health - Four Walls” Claudia Hammond talks to ex political prisoners about their experiences and how they dealt with living in such inhumane conditions. Advice too from Professor Craig Heaney who works with prisoners in Supermax prisons in the United States of America and psychiatrist Professor David Alexander who has worked with many hostages.
