>… Generally, people are thought to spend 20 percent of their night in slow-wave sleep, and the study’s white participants hit this mark. Black participants, however, spent only about 15 percent of the night in slow-wave sleep.
>The study was just one data point in a mounting pile of evidence that black Americans aren’t sleeping as well as whites. This past June, the journal Sleep published a study on the sleep quality of black, white, Chinese, and Hispanic adults in six cities across the United States. …
>The results? “The insufficient amount of sleep, the short sleep duration of the African-Americans really stood out,” says Susan Redline, a Harvard professor of sleep medicine and one of the study’s co-authors. “It really emphasized that African-Americans, as a group, are getting the least amount of sleep compared, at least, to the three other groups.” Whites in the study slept an average of 6.85 hours; blacks slept an average of 6.05 hours.
>Studying a 669-person cohort in Chicago—44 percent were black; the rest were white—she and her colleagues found, on average, an hour difference between blacks’ and whites’ sleep.
>ON THE QUESTION of how to explain the black-white sleep gap itself, researchers have a number of related theories. (There is a consensus that innate biological differences between blacks and whites are not a factor.) The stress caused by discrimination is one strong possibility. …
