Story summary

Antoinette M. Landor and colleagues find that darker-skinned young adults in the United States experience higher ethnic discrimination.
This discrimination correlates with physiological stress evidenced by hormonal changes.
Darker-skinned participants show flatter diurnal cortisol slopes, indicating disrupted stress regulation.
The study notes that colorism is distinct from racism and creates unique health risks requiring targeted interventions.
Limitations include a small sample size and reliance on self-reported data, so research across diverse demographics is needed.
