Race and sleep: 11 surprising facts

White men are the earliest risers — except on weekends (when black women beat them out of bed by 52 minutes)

Sleep is an increasingly precious commodity in today's America.

Intriguingly, when it comes to getting a good night's rest, some ethnic groups fare better than others. Here, a by-the-numbers breakdown of who's sleepless in America and why:

The percentage of African Americans and Hispanics who say they have trouble sleeping at least a few nights a week because of worries about money, health, or love
