I thought this book was okay to read but I don't think he is clear about how to heal. Nobel is a primary-care physician and I think he advocates for being creative to boost your mental health. I'm not sure if that's his solution because the book doesn't seem properly structured. Some of the chapters that I don't write about cover loneliness and how aging and illness affect it. I was already aware that there were was a health cost to loneliness.
In Chapter 1 - The Loneliness Crisis on page 12 the author writes "Loneliness is defined by social psychologists as the feeling that there is a gap between the connections we would like to have with other people and what we actually experience. Loneliness is experienced as 'something missing.'"
He goes on to write on page 13 that "Loneliness is a natural biological signal, like hunger or thirst. "
In Chapter 2 - The Power of Creative Expression on page 27, the author references a 2015 study called "Loneliness and Social Isolation as Risk Factors for Mortality: A Meta-analytic Review" which was published by Brigham Young University's Julianne Holt-Lunstad. This paper outlines the medical impact of loneliness. The study concluded that people without strong social relationships were 30% more likely to die prematurely than socially connected people, controlling for age, sex, health status, illness, and cause of death. The lack of social relationships was comparable in importance with other well established risk factors for an early demise, such as smoking, sedentary lifestyle, and obesity.
On pages 27-28 the author references FAH which is the Foundation for Art & Healing. He writes that "Sharing your story through creative expression has the power to restore your sense of self-regard, support your habits of self-care, and bring you closer to others who can lend you further support for your well-being."
On page 29 the author writes "For many lonely people, a primary source of their disconnection from others is their broken connection with their inner selves. When we feel lost to ourselves or inside ourselves, for whatever reason, making a connection with others feels fraudulent, elusive, or impossible."
In Chapter 3 - Our Loneliness Heritage on page 36 the author writes that the root course of loneliness isn't dealt with by getting a pet or joining a book group. Activities themselves are not the answer.
I may have missed it, but the author doesn't address what the root cause of loneliness is or how to treat it. He does hint that it's a disconnect from the self but never goes beyond that.
He outlines 3 other types of loneliness in this chapter and they are:
1. Psychological loneliness (page 38)
2. Societal loneliness (page 39)
3. Existential loneliness (page 41)
In Chapter 4 - Trauma the author talks about PTSD and how people with that disorder are at risk for isolation because they learn to avoid people who may trigger a flashback. On page 85 author has an image of what he calls the "Pyramid of Vulnerability for Loneliness." The bottom is "At Risk for Loneliness," followed by "Beginning to Disconnect and Isolate," and the top is "Highly Isolated."
