Research suggests relationships may be as vital to good health as abalanced diet and plenty of rest


Choose your friends wisely, they may make or break you, says an old adage.

Now, scientists have ba

cked it after finding link between toxic relationship and a host of illnesses such as cancer, depression and heart attack, reports PTI. Researchers at the University of California Los Angeles found that negative social interactions can lead to increased inflammation, which may in turn cause a host of illnesses from cancer to heart disease and high blood pressure.

” We wanted to see how mental states such as optimism, or social relationships such as competition, get under the skin,” study co- author Shelley Taylor, a social neuroscientist at the UCLA School of Medicine, was quoted as saying by ScienceNews.

For their study, published in the Proceedings of the National Academy of Sciences journal, Taylor and colleagues looked at the relationship between day- today stress and two proteins that trigger inflammation in the body, called pro- inflammatory

inflammatory cytokines. The researchers asked 122 young, healthy adults to keep a diary of all positive and negative social interactions for eight days, as well as descriptions of any incidents that involved

competition. ” We picked young adults with no history of heart disease or inflammation disorders or depression because we wanted to look at the biological processes in a population that was healthy,” Taylor said.

Several days later, they swabbed the volunteersalt39 inner cheeks for fluid samples.

Analyses revealed that the people with the most negative social interactions recorded in their diaries, and those who reported stressful competition in work or academic pursuits, had substantially higher levels of one of the inflammatory proteins, TNF receptor 2, than did those who recorded fewer such incidents. People reporting stressful competition for anothers attention had high concentrations of the other inflammatory protein, interleukin- 6.
