Being a parent reduces your risk of catching a cold -- possibly because of unknown "psychological or behavioral differences between parents and nonparents," according to a study in the July issue of Psychosomatic Medicine, the official journal of the American Psychosomatic Society.
The risk of becoming ill after exposure to cold viruses is reduced by about half in parents compared to nonparents, regardless of pre-existing immunity, according to research led by Rodlescia S. Sneed, MPH, and Sheldon Cohen, PhD of Carnegie Mellon University, Pittsburgh. The study suggests that other, yet unknown factors related to being a parent may affect susceptibility to illness.
Being a Parent Protects Against Colds
The researchers analyzed data on 795 adults from three previous studies of stress and social factors affecting susceptibility to the common cold. In those studies, healthy volunteers were given nose drops containing cold-causing rhinovirus or influenza viruses.
After virus exposure, about one-third of volunteers developed clinical colds -- typical symptoms of a cold plus confirmed infection with one of the study viruses. The analysis focused on whether being a parent affected the risk of developing a cold, with adjustment for other factors.
The results showed a lower rate of colds among parents, compared to volunteers who were not parents. In the adjusted analysis, the risk of developing a cold was 52 percent lower for parents.
