Shiftwork leads to sleep problems in 30- to 40-year-olds: study

April 15, 2010

Shiftwork's negative impact on sleep patterns seems to be experienced most severely by workers in their 30s and 40s, finds a new study from the American College of Occupational and Environmental Medicine in Elk Grove Village, IL.

According to a study abstract, the most common sleep issue associated with shiftwork is waking up too early.

Although former shiftworkers tend to have more sleep problems than people who have never performed shiftwork, study authors believe the effects are reversible -- but it may take some time after giving up shiftwork for sleep patterns to normalize.

The study was published in the April issue of the Journal of Occupational and Environmental Medicine.
