The world seems more connected than ever, and yet loneliness is at epidemic levels. But what effect is it having on us, and how can we treat it - even at a distance?

When Obama appointed him Surgeon General of the United States, Dr Vivek Murthy observed the growing health crisis of isolation first-hand. In this ground-breaking book, he traces the roots of the problem, and shows how loneliness lies behind some of our greatest personal and social challenges, from anxiety and depression to addiction and violence. But he also reveals the cure. His search led him to talk to doctors, scientists, parents and community members around the world. The solutions are deceptively simple and easily applicable - and the effects are transformative. And one thing is clear: real human connection is a medical necessity if we want to stay healthy. We can all create it, and benefit from it, and it is more urgent than ever that we start now.
