If you’ve ever been on Facebook past midnight, you already know that nobody in this country is sleeping. Well it turns out that just how little people sleep actually depends on race. Research has shown over and over that black people in America tend to sleep about an hour less than whites, who get the most and highest quality sleep of anyone. (Hispanics fall somewhere in the middle.) What researchers don’t yet know is why, though they have some pretty good guesses.
