July 6, 2012 -- A new study suggests that being a parent may boost immunity to cold-causing viruses, though researchers acknowledge it may not always feel that way.

In a series of experiments where adults had viruses placed directly into their noses, parents were about half as likely to get sick as adults who did not have children.

Researchers are quick to say, however, that the study doesn't mean that parents get fewer colds, overall, than people who don't have kids.

"We're not saying that parents are exposed to fewer viruses. I think people will probably agree that parents are exposed to stuff constantly, whether you have kids going to day care or going to school or being around other children," says researcher Rodlescia S. Sneed, MPH, a doctoral student in the psychology department at Carnegie Mellon University in Pittsburgh, Pa. "But that's a little bit different than the question we're asking."

Parenting and the Immune System

For the study, researchers took a second look at three different experiments where adults were exposed to viruses that cause colds. The three experiments included nearly 800 healthy adults who were between the ages of 18 and 55. Forty-two percent of adults in the study were parents.

Before the study, people were asked about a variety of things that are known to affect health, like sleep, smoking, alcohol use, stress, education, and marital status. They were also asked about social support they might get from friends, family, and co-workers. Blood tests were used to measure the level of antibodies that study participants might already have against the viruses that were used in the studies.

After spending a day in quarantine to make sure they weren't already coming down with some kind of bug, researchers put drops containing cold viruses directly into their noses. People in the studies then spent five to six days sequestered in a lab. Blood tests showed that about three quarters of study participants were infected by the viruses. But only about one-third (32%) developed the sneezy, watery-eyed, congested misery of a full-blown cold.

Parents were about half as likely to catch colds from the viruses as childless adults. The protection seemed to go up the more children a person had. Parents who did not live with their children saw the greatest protection of all. They were about 75% less likely to get sick after being exposed to the viruses compared to adults who didn't have children.
