研究：寂寞伤神又伤身

In the first study, the researchers analyzed the blood of the breast cancer survivors for antibodies against cytomegalovirus, a herpes virus. These common viruses can remain dormant and symptomless inside the body. Even when active, they may not cause symptoms, but they do trigger the immune system to produce antibodies, or protective proteins that help the immune system hunt down the rogue viruses. Higher antibody levels indicate higher levels of activated virus. The participants also filled out questionnaires about their loneliness and social connectedness.

The results revealed that the lonelier the participant, the higher the levels of cytomegalovirus antibodies in the blood.

"It's definitely indicating that the immune system is compromised in some way," Jaremka told LiveScience. "It's unable at that time, for whatever reason, in this case loneliness perhaps, to keep that virus under control."

In a second study, the researchers measured inflammatory proteins called cytokines in 144 of the breast cancer survivors as well as the healthy though overweight middle-age adults. The participants gave a blood sample and then were subjected to the stress of having to give an impromptu speech and do mental math in front of a panel of people in white lab coats. To up the anxiety, the panel gave the participants no encouragement.
