If attachment anxiety does cause the changes seen, this study suggests how social relationships can affect health and wellbeing. They move in and out of tissues and organs, defending the body against foreign bodies (antigens), such as bacteria, viruses and cancerous cells. Most scientists studying the relationship of stress and immune function, however, do not study a sudden, short-lived stressor; rather, they try to study more constant and frequent stressors known as chronic stress, such as that caused by relationships with family, friends, and co-workers, or sustained challenges to perform well at one's work.

The ability to fend off illness and disease depends on several factors, some of which are beyond our control, but the way we react to and the general health of our immune system are things we can influence.

Drops of the common cold virus were then dripped into their nose and scientists checked if they caught the germ. The researchers analysed whether there was an association between attachment anxiety and levels of cortisol and T cells taking into account that participants were husband and wife pairs, and including body mass index (BMI), age, gender, attachment avoidance and general anxiety symptoms as control variables.
