This is the VOA Special English Health Report.
|A demonstration last May against loneliness in Rio de Janeiro, Brazil. Signs read in Portuguese "Tired of being alone," "Couple now" and "I want to be in love."|
Earlier findings showed that happiness, obesity and the ability to stop smoking can also spread like infections within social groups. The findings all come from a major health study in the American town of Framingham, Massachusetts.
The new findings involved more than five thousand people in the second generation of the Framingham Heart Study. The researchers examined friendship histories and reports of loneliness. The results established a pattern that spread as people reported fewer close friends.
For example, loneliness can affect relationships between next-door neighbors. The loneliness spreads as neighbors who were close friends now spend less time together. The study also found that loneliness spreads more easily among women than men.
Researchers from the University of Chicago, Harvard and the University of California, San Diego, did the study. The findings appeared last month in the Journal of Personality and Social Psychology.
The average person is said to experience feelings of loneliness about forty-eight days a year. The study found that having a lonely friend can add about seventeen days. But every additional friend can decrease loneliness by about five percent, or two and a half days.
Lonely people become less and less trusting of others. This makes it more and more difficult for them to make friends -- and more likely that society will reject them.
John Cacioppo at the University of Chicago led the study. He says it is important to recognize and deal with loneliness. He says people who have been pushed to the edges of society should receive help to repair their social networks.
The aim should be to aggressively create what he calls a "protective barrier" against loneliness. This barrier, he says, can keep the whole network from coming apart.
