Perceptions of racism may cause loss of sleep and perhaps loss of sleep may also impact perceptions of racism.

A new study has found that self-reported sleep disturbance correlated to perceived racism, which was increased by 61 percent after adjusting for socioeconomic factors and symptoms of depression.
