Definition
Social stress — rejection, conflict, marginalization, low social status — produces measurable immune changes, including shifts in gene expression toward pro-inflammatory profiles.
Why it matters
The nervous system reads social threat as biological threat. Immunity follows.
The Science
Steve Cole and colleagues documented the Conserved Transcriptional Response to Adversity (CTRA), in which chronic social stress upregulates pro-inflammatory gene expression while dampening antiviral defense. These patterns show across studies of loneliness, low SES, caregiving strain, and marginalization.
The NSI Perspective
NSI treats social context as biological input. Care that ignores it is incomplete care.
Clinical Implications
Social prescribing and community-based interventions have real immune targets, not only psychological ones.
Practical Application
If you have felt worn down by social pain, that was not weakness. That was your immune system listening.
