Little is known about the impact of ethnic microaggressions (MA) on stress reactivity. The purpose of the current study was to examine how the frequency with which college students (n = 109) experience MA and their reactions to them relate to a biomarker of stress (i.e. salivary cortisol). Participants were exposed to the Trier Social Stress Test (TSST) and answered questions about the frequency of experiences of ethnic MA and their reaction to them (e.g. getting upset). Cortisol reactivity, cortisol recovery, and Area Under the Curve (AUC) were also assessed. Results of hierarchical regressions suggest that negative MA reactivity (i.e. getting upset) was associated with faster recovery and smaller AUC. Additionally, having high frequency of MA and high MA reactivity was associated with a blunted cortisol reactivity. Blunted cortisol responses may have negative health implications, as they have been associated to substance use, smoking, and obesity.
