How does racism affect the nervous system?
Racism affects the nervous system through the same mechanisms as any chronic threat: it activates the HPA axis and sympathetic arousal response, suppresses the social engagement system, generates hypervigilance that cannot fully relax, and produces measurable physiological changes including altered cortisol profiles, shortened telomeres, and elevated inflammatory markers. Dr. Resmaa Menakem documents racism as body-held trauma.
Dr. Resmaa Menakem, licensed therapist and author of My Grandmother's Hands, argues that racism is not only a social and political phenomenon but a body-held trauma: one that is stored in the nervous systems of both those who are targeted and those who perpetrate it, transmitted across generations through nervous system patterns rather than only through conscious ideology. The body responds to racism as it responds to any sustained threat.
Research by Dr. Arline Geronimus at the University of Michigan established that exposure to systemic racism produces measurable biological consequences: elevated cortisol profiles, shortened telomeres (a cellular marker of biological aging), and health outcomes that track with the degree of racial discrimination experienced rather than simply with socioeconomic status. The body wears the cumulative cost of sustained vigilance required to navigate racist environments.
Dr. Monnica Williams at the University of Connecticut has documented race-based traumatic stress as a clinical entity with symptoms distinct from generalized PTSD: hypervigilance specifically in response to racial stimuli, intrusive recollections of race-based incidents, avoidance of environments associated with discrimination, and a generalized threat response that does not distinguish between safe and unsafe racial contexts because the history of threat has been pervasive.
Healing approaches must be culturally competent in recognizing that the ongoing exposure to racism that Black, Indigenous, and people of color experience is not resolved by individual therapeutic work alone. Menakem emphasizes somatic healing within community contexts as essential: healing nervous systems in relationship with others who share the history of the wound, combined with cultural practices that affirm rather than further erode the sense of belonging and worth.
