A growing body of evidence is prompting researchers to explore how sleep patterns may explain the health gap between blacks and whites in the US, according to a Quartz news report.
Now a growing body of evidence is making researchers wonder whether variations in sleep patterns may go some way to explain the health gap. Sleeping too little or too much increases the risk of cardiovascular disease. People who were sleep-deprived for one to three weeks performed much more poorly on cognitive tasks than those who slept well. In 2014, the US Centers for Disease Control (CDC) declared that insufficient sleep has become a “public-health epidemic.”In its report, CDC highlighted that as a proportion of the population, blacks slept much less than all other races.
