Loneliness May Warp Our Genes, And Our Immune Systems

NPR:

Loneliness has been linked to everything from heart disease to Alzheimer’s disease. Depression is common among the lonely. Cancers tear through their bodies more rapidly, and viruses hit them harder and more frequently. In the short term, it feels like the loneliness will kill you. A study suggests that’s because the pain of loneliness activates the immune pattern of a primordial response commonly known as fight or flight

For decades, researchers have been seeing signs that the immune systems of lonely people are working differently. Lonely people’s white blood cells seem to be more active in a way that increases inflammation, a natural immune response to wounding and bacterial infection. On top of that, they seem to have lower levels of antiviral compounds known as interferons.

But this fight-or-flight immune response is really nonspecific, says Turhan Canli, a neuroscientist at Stony Brook University in New York who was not involved with the study. Loneliness might not necessarily have to do with ancient survival, he says. Our bodies basically have one panic button, and any kind of adverse condition can trigger this response. “I think loneliness is a kind of psychological stress,” he says. “The change in the immune response is part of biological changes that come with a stress condition.”
