We examined the effect of indirect ethnic discrimination on physiological reactivity (i.e., cortisol, blood pressure, heart rate) in Latino emerging adults.
Participants (N = 32) were randomly assigned to be exposed to indirect ethnic discrimination (experimental condition) or not (control condition) while undergoing a cognitive stress task.
Greater total cortisol output was observed in participants in the experimental condition, relative to those in the control condition. No significant differences in heart rate or blood pressure were noted.
Results suggest that witnessing ethnic discrimination affects cortisol recovery responses, but not cardiovascular reactivity. Words that are not intentionally hurtful or directed at a specific person may still "hurt"-affecting biological processes associated with hypothalamic-pituitary-adrenocortical (HPA) axis and potentially leading to long-term health consequences.

我们研究了间接种族歧视对拉丁裔青年人生理反应（即皮质醇、血压、心率）的影响。
参与者（N=32）在进行认知应激任务时，被随机分配到暴露于间接种族歧视（实验组）或不暴露于间接种族歧视（对照组）的条件下。
实验组参与者的总皮质醇分泌量大于对照组。心率或血压没有显著差异。
结果表明，目睹种族歧视会影响皮质醇的恢复反应，但不会影响心血管反应。无意的、不针对特定个人的伤人言语仍可能“伤人”——影响与下丘脑-垂体-肾上腺皮质轴（HPA）相关的生物过程，并可能导致长期健康后果。
