Anxieties and concerns and about one’s close relationships could prove to be a chronic stressor that can compromise immunity, a new study has found.
In the study, researchers asked married couples to complete questionnaires about their relationships and collected saliva and blood samples to test participants’ levels of a key stress-related hormone and numbers of certain immune cells.
The research focused on attachment anxiety. Those who are on the high end of the attachment anxiety spectrum are excessively concerned about being rejected, have a tendency to constantly seek reassurance that they are loved, and are more likely to interpret ambiguous events in a relationship as negative.
Married partners who were more anxiously attached produced higher levels of cortisol, a steroid hormone that is released in response to stress, and had fewer T cells – important components of the immune system’s defense against infection – than did participants who were less anxiously attached.
