Insomnia is a growing problem, but a new study reveals that this sleep problem is affecting one group of people more than others. Multiple recent studies have found that African Americans sleep fewer hours, wake up more times in the middle of the night, and are more likely to take some sort of sleep aid. The reasons for these sleep problems are varied. According to the studies, 17-percent of African Americans reported doing work-related tasks in the hour before they go to bed, compared to 9-percent of whites and 13-percent of Hispanics. In addition, the researchers note that this problem has shown its face in popular culture recently. Rapper Rick Ross claims his two November 2011 seizures were the result of not getting a good night’s sleep for many years.
