Blood Pressure and Social Algesia: The Unexpected Relationship Between the Cardiovascular System and Sensitivity to Social Pain

Threats to social connectedness in the form of social and societal rejection, and the permanent loss of social bonds, are inevitable and common sources of social pain. However, sensitivity to social pain, also known as algesia, differs across individuals and contexts. Such sensitivity has implications for health, well-being, and the maintenance of social connection over time. What biological factors predict differences in sensitivity to social pain? Based on long-standing translational perspectives and emerging findings, the current review highlights blood pressure as a novel predictor of sensitivity to social pain: Higher resting blood pressure appears to relate to lower sensitivity to social pain. Despite evidence for this association, possible psychobiological bases and moderating influences are not yet established. Moreover, although higher blood pressure may afford tolerance for life’s many pains, the health-related implications and trade-offs of such an effect are unknown.
