一项最新研究显示，孤单寂寞的人不但精神状态不佳，其免疫系统也会因此受到破坏。该研究发现，社交活动贫乏的寂寞人群体内的潜藏细菌再生率要高于社交广泛的人群；他们体内产生的炎性化合物也要高于后者，炎性化合物是指向心脏病和其他慢性疾病的指标之一。研究人员还发现，寂寞人群对于生活中发生的消极事件反应往往更加激烈，由此便会产生长期精神压力，从而使免疫系统受到破坏。 Feeling lonely? New research suggests you might want to reach out. Not only is loneliness an unpleasant condition, it can harm the body's immune system. The new study, presented Saturday (Jan. 19) at the annual meeting of the Society for Personality and Social Psychology, reveals that people who are lonely experience more reactivation of latent viruses in their systems than the well-connected. Lonely people also are more likely than others to produce inflammatory compounds in response to stress, a factor implicated in heart disease and other chronic disorders. "Both, in different ways, indicate that the immune system is a little out of whack," said study researcher Lisa Jaremka, a postdoctoral fellow at the Institute for Behavioral Medicine Research at Ohio State University College of Medicine. Jaremka and her colleagues were interested in immune links to loneliness because feeling socially disconnected is associated with poor health and chronic disease. They recruited 200 female breast cancer survivors, average age 51, and 134 overweight, middle-age adults with no major health problems. |
