A new study has found that African-Americans get less sleep than whites do -- and the reason is mainly career stress.
According to the study, posted in the American Journal of Epidemiology, 37 percent of black participants got fewer than seven hours of sleep a night, compared to only 28 percent of white participants.
The study also found that the when African-Americans entered management level positions, the difference became even more pronounced, with 42 percent of black in managerial positions not getting enough sleep, compared to 26 percent of whites. 37 percent of black people in support services didn't get enough sleep, compared to only 26 percent of whites. And among laborers, 35 percent of blacks didn't get enough sleep, compared to 32 percent of whites.
The only area where blacks and whites struggled with sleep at the same level was among those who work in the retail and food industries.
