Shift Work: Shift Sleep
Almost 15 million workers are considered shift workers in America. 1 Shift work is known as working long shifts with little time off, usually including a night shift or rotating shifts. While this type of work increases productivity, it has the potential to reap havoc on the sleep patterns of those affected. The most common type of shift work is known as the “seven swing” in which there are seven days of work with an eight-hour morning shift followed by two days of rest. 2 Following the rest the individual will work another seven days with eight-hour night shifts and continuing the pattern with different shifts. 1 This type of schedule will essentially be like traveling and never being on a consistent sleep schedule. This causes these workers to exhibit the symptoms of jet lag on a nearly consistent basis.
Shift work is common for doctors, nurses, commercial drivers and law enforcement officials. Shift workers typically do 400 more hours of work a year than individuals with a typical 40-hour work week. 2
Because shift-workers are never on a consistent schedule, they typically have a hard time going to sleep and staying awake at work because their circadian rhythm is irregular. The circadian rhythm is regulated by the cycles of light and dark throughout the day. 3 The occasional weekend off tends to leave the worker with no other choice than to attempt to catch up on sleep, which leads to neglect of family, friends and other aspects of life important to the individual. Shift workers often use alcohol to help fall asleep and cigarettes and caffeine to help stay awake. 2 These techniques only serve to make sleeping more difficult.
Because of the intense stressors on the lives of shift workers, 70 percent report having difficulty falling asleep and average one to two hours less sleep than typical 40-hour a week workers. 2
