Perceived economic inequality is linked to poorer sleep quality.

ABSTRACT: Economic inequality is believed to negatively affect individuals' psychological and physical health. We hypothesized that perceptions of greater economic inequality predict poorer sleep quality through social comparison and stress. We tested this hypothesis across three studies.
