Baby Monkey Gangs Reveal Genetic Effects of Loneliness
Loneliness isn’t just a state of mind. It also affects our bodies. A growing number of studies are showing that a feeling of loneliness is associated with heart problems, viral infections, and an increased risk of death. And those health problems, in turn, are associated with huge differences in gene activity. Some genes, like ones involved in inflammation, are more active in lonely people. Others, such as genes that code for antiviral defenses, are less active.
