Stress caused by social situations, such as giving a speech or going to a job interview, can affect some people’s immune system in ways that harm their health, researchers have found.
The study included 124 volunteers who were purposely put into embarrassed social situations. Those who showed greater neural (神经) sensitivity to social rejection also had greater increases in inflammatory (炎症) activity when exposed to social stress.
“It turns out there are important differences in how people explain and respond to social situations,” lead author George Slavich, at the Cousins Center for Psychoneuroimmunology at the University of California, Los Angeles, said in a UCLA news release.
“For example,” he explained, “we sometimes see giving a speech in front of an audience as a welcomed challenge; other times, it’s threatening and sad. In this study, we sought to examine the neural bases for these differences in response and to understand how these differences relate to biological processes that can affect human health and well-being.”
