Dr. McGonigal's advice is inspiring, down-to-earth, and easy to put into action right away.
I have been doing the breathing exercises and meditations with my wife, who began suffering from chronic headaches after a concussion this past summer. She wanted to avoid heavy pain medications, and this book was a lifesaver. It helped both with the physical pain and also the depression and anxiety that she felt, having little control over her symptoms. I was happy to be able to work through the book with her -- it helped me better understand what she going through, and gave me concrete ways to help her: by doing breathing exercises together, and reading the meditations out loud to her.
It helps that the book is grounded in scientific research (psychology and physiology) as well as Dr. McGonigal's yoga practice, it makes for a well-grounded book that is both eye-opening and comforting.
