Another article about sleep from Scientific American:
An ability to get the right amount of shut-eye each night differs depending on race, ethnicity and your birthplace
Scientists have now found significant differences exist in how people sleep in the U.S. depending on race, ethnicity and country of origin, suggesting genetic or cultural differences in shut-eye patterns. This line of research could help identify how these disparities might affect health and find better ways to improve sleep.
Differences in sleep patterns might stem from genetic and anatomical variations between groups. For instance, past research suggests blacks and whites might sleep differently because of disparities in inflammation responses and that various groups might display distinctive the structure in their airways, influencing how they breathe during sleep, Pandey says.
Grandner notes such biological distinctions are embedded within a context of familial, cultural, neighborhood and other social factors. "It is only when we can come to grips with this multilayered environment that we can understand why different groups of people experience differences in sleep," he says. "If this seems too daunting, just remember that this is the exact sort of work that was recognized as needed for other domains of healthy behavior, such as healthy diet, adequate exercise, decreased alcohol use and decreased smoking."
