Racial stress and discrimination causes black adolescents and adults to get less sleep than white people, as reported by Atlanta Blackstar.
Researcher Emma Adam from Northwestern University has discovered that young adults from racial/ethnic minority groups who experience more discrimination have higher levels of cortisol in the evening, and less decline in cortisol levels throughout the day, than those with lower discrimination. Flatter cortisol rhythms across the day have been linked to a long list of problems, such as higher fatigue, poor mental health, cardiovascular disease and failing memory.
