Loneliness grows from individual ache to public health hazard
By Amy Ellis Nutt January 31

Loneliness, long a bane of humanity, is increasingly seen today as a serious public health hazard. Scientists who have identified significant links between loneliness and illness are pursuing the precise biological mechanisms that make it such a menace, digging down to the molecular level and finding that social isolation changes the human genome in profound, long-lasting ways. ... Not only that, but the potential for damage caused by these genetic changes appears comparable to the injuries to health from smoking and, even worse, from diabetes and obesity. The scientists’ conclusion: Loneliness can be a lethal risk. And the United States — which so prizes individuality — is doing far too little to alleviate it.

“In public health, we talk all the time about obesity and smoking and have all these interventions, but not about people who are lonely and socially isolated,” said Kerstin Gerst Emerson, an assistant professor at the University of Georgia’s Institute of Gerontology. “There are really tangible, terrible outcomes. Lonely people are dying, they’re less healthy, and they are costing our society more.”
....
Then last year, {psychologist Steve Cole} and his colleagues at the UCLA School of Medicine, along with collaborators at the University of California at Davis and the University of Chicago, uncovered complex immune system responses at work in lonely people. They found that social isolation turned up the activity of genes responsible for inflammation and turned down the activity of genes that produce antibodies to fight infection.
The abnormalities were discovered in monocytes, a type of white blood cell, produced in the bone marrow, that is dramatically changed in people who are socially isolated. Monocytes play a special immunological role and are one of the body’s first lines of defense against infection. However, immature monocytes cause inflammation and reduce antibody protection. And they are what proliferates in the blood of lonely people.
....
The most broadly accepted definition of loneliness is the distress people feel when reality fails to meet their ideal of social relationships. Loneliness is not synonymous with being alone. Many people live solitary lives but are not lonely. Conversely, being surrounded by others is no guarantee against loneliness.
