Bad sleep may fuel health disparities in America, reports Vox.
Research shows black Americans on average simply don’t sleep as well white Americans do. They don’t sleep as long, they don’t sleep through the night as often, and they suffer more heavily from sleep apnea, a potentially life-threatening disorder. Other minority groups, such as Latinos and Asian Americans, also sleep more poorly than white Americans. But the differences are starkest in black communities.
