Not Getting Enough Sleep? Blame Your Job. If you're not sleeping for more than seven hours a night, it may be time to rethink your schedule … or your career.

Are you getting enough sleep? If you're not getting at least seven hours of sleep or more every day, the answer is likely "no," according to the American Academy of Sleep Medicine and the Sleep Research Society.

A shortage of sleep, classified as less than seven hours a day, can result in conditions such as cardiovascular disease, obesity, diabetes, depression and anxiety. Although, the amount of sleep a person gets every night is impacted by a diversity of factors, such as race, education, marital status, obesity, cigarette smoking and career. In fact, work is a major factor that can negatively impact sleep, from stress to shift hours to the actual work itself.

In a recent study conducted by the Centers for Disease Control and Prevention (CDC), the agency analyzed data from employed adults in 29 states who participated in the 2013 and 2014 Behavioral Risk Factor Surveillance System (BRFSS), an annual telephone survey that gathers data on health-related issues. The CDC uncovered information about sleep and its relationship to work, taking into account responses of 179,621 employed individuals across 22 major industries, also examining age group, sex, ethnicity, marital status and education level.

If you think you're not getting enough sleep, you're not alone -- overall, an average of 36.5 percent of currently employed adults admitted to not getting enough sleep every night. Yet the younger you are, the more likely you are to fall into this sleepless category. Nearly 38 percent of people between the ages of 18 to 34 say they experience a shortage of sleep, while approximately 29 percent of people 65 and older say they don't get a full night's rest.

Slightly above the overall average, male respondents (37.5 percent) reported they get less sleep than females. Nearly half of non-Hispanic black respondents (48.5 percent) say they got a shortage of sleep too. And people with some college education (40 percent) were also seen to have higher numbers of sleep shortages, as well as people who are divorced, widowed, separated or never married (39.5 percent).

Other transportation workers (54 percent) and rail transportation workers (52.7 percent) were also among the top careers who experience a lack of sleep. To the contrary, air transportation employees reported getting the most amount of sleep out of all 93 subcategories, with only 21.4 percent saying they experience a sleep shortage.
