Feeling lonely can make you sick. Doctors have long known that loneliness can cause many health problems and even death. What they didn’t know is   16  this feeling causes illness. A study in the online magazine Genome Biology  17  that loneliness actually influences the important part of our bodies—our genes.
In a small population of patients, researchers   18  more than 20,000 genes to compare how the genes of lonely and non-lonely individuals (個(gè)體) express themselves in molecular processes (分子過(guò)程) and in personal health. They found that gene expression is   19  in chronically (長(zhǎng)期地) lonely people. “We now have a new way for understanding the relationship   20   social experience and physical health,” explains the study’s lead author, Steve Cole of University of California, Los Angeles.
“This study—the first to link (聯(lián)系)   21  with gene changes—is special and exciting,” says Emma Adam, a professor of human development at Northwestern University. “It   22  in the black box.”
According to John Cacioppo, an author of the study from the University of Chicago, the
work suggests that loneliness is a warning   23 , much like physical pain. “This feeling is so bad because   24  of us wants to be forgotten; that’ s also what human means,” he says. “It makes us   25  for other people and want to be with friends when we’re lonely.”
