As more and more build up in the body, they promote conditions of aging, such as osteoporosis, chronic obstructive pulmonary disease and Alzheimer's disease.

In addition to finding that people who reported higher stress levels had more zombie cells, Klopack and his team found they also had fewer "naive" T cells, which are the young, fresh cells needed to take on new invaders.

"This paper adds to findings that psychological stress on one hand, and well-being and resources on the other hand, are associated with immunological aging," said clinical psychologist Suzanne Segerstrom, who was not involved with the study.

Segerstrom, a professor of developmental, social and health psychology at the University of Kentucky in Lexington, has studied the connection between self-regulation, stress and immune function.

"In one of our newer studies ...

People in the study were asked questions about their levels of social stress, which included "stressful life events, chronic stress, everyday discrimination and lifetime discrimination," Klopack said.

Their responses were then compared with levels of T-cells found in their blood tests.

"It's the first time detailed information about immune cells has been collected in a large national survey," Klopack said.

"We found older adults with low proportions of naive cells and high proportions of older T cells have a more aged immune system."

The study found the association between stressful life events and fewer naive T cells remained strong even after controlling for education, smoking, drinking, weight and race or ethnicity, Klopack said.
