In the UK, one in four of us will experience a mental health problem at some point in their lives. And according to the latest stats, one in eight young people have a mental health problem. One big problem is access to treatment. Mental health services are underfunded, leaving many people stuck on waiting lists. But what are the wider social and economic factors that are causing poor mental health in the first place? Is the economy itself damaging our mental health? Is modern life making us sick? Ayeisha Thomas-Smith talks to Hana Riaz, who is researching the impact of gentrification on mental health, NEF organiser Becki Winson, and our wellbeing researcher Annie Quick.
