    Loneliness May Hurt Your Health

    Researchers Say Lonely College Freshmen Show Weaker Immune Response

    May 2, 2005 -- Loneliness may hamper the immune system, which is needed to fight off illness.

    That's what Carnegie Mellon University psychology graduate student Sarah Pressman, MS, and colleagues found when they studied college freshmen coping with their first semester away from home.

    The freshmen who felt the loneliest and most socially isolated had the weakest immune response to one component of the flu virus, says Pressman.

    The results -- published in May's Health Psychology -- show that loneliness and social isolation can have an impact and that the first semester of college can be "really stressful," Pressman tells WebMD.

    Emotional Feeling, Physical Effect

    College students aren't the only ones whose health may suffer with those feelings. "Loneliness and social isolation have previously been associated with immune detriments," says Pressman.

    "As you get older, the immune system doesn't work as well," she says, noting that older people's social networks sometimes thin as friends and family move away or die.

    A study of 180 senior citizens found an association between loneliness and heart disease. That report appeared in the December 2002 issue of the Annals of Internal Medicine.

    Campus Study

    Pressman's study included 83 first-semester college students. All were healthy and got their first-ever flu shots on campus, along with the rest of their class.

    Researchers often use students' response to flu shots as a measure of immunity. "The nice thing is it's a bit more relevant than a blood draw and looking at circulating antibodies," says Pressman.

    Two days before the flu shot, the students were given palm-held computers that prompted them to rate how lonely and isolated they were feeling at that moment on a scale of one to four. The computer tests popped up four times each day for about two weeks.

    The students also wrote down the initials of all the people they had contact with at least once every two weeks.

    Pressman and colleagues grouped the students in two ways: by degree of loneliness (low, medium, or high), and by social-network size (smaller, medium, or larger).
