Shift work disorder (SWD) is a recognized medical condition that can be diagnosed and treated. It occurs when the body's internal clock, or circadian rhythm, is out of sync with your work schedule. The circadian rhythm helps regulate different functions; including sleeping and waking. Disruption of the circadian rhythm can lead to excessive sleepiness during waking hours and or trouble sleeping during sleeping hours.
SWD Is Common
- As many as 20% of US workers are involved in some form of shift work, including permanent or intermittent night work, early morning work, or rotating schedules.
- Approximately 10% to 25% of night-workers and rotating-shift workers have what is known as Shift Work Disorder, which means 1 out of every 4 nights of rotating-shifts, an employee may suffer from sleep related problems.
- Over 15 million Americans work non-traditional shifts and are "at risk" for SWD. Of these, 3.75 million Americans are estimated to have SWD.
Signs a Person Could Have SWD
Shift work disorder is an often undiagnosed condition in which excessive sleepiness and/or insomnia are the main symptoms.
- Excessive Sleepiness
Excessive sleepiness is defined as having trouble staying awake. People who experience excessive sleepiness often describe it as being tired, fatigued or lacking energy.
Insomnia affects the length and quality of sleep. Insomnia can be difficulty falling asleep, difficulty staying asleep, waking up too early, and poor quality of sleep.
SWD can lead to other quality of life concerns
These are just some of the problems people with shift work disorder may experience:
- Trouble focusing
- Drop in work performance
- Missed family and social activities
- Worsening of heart and stomach disorders
- Sleepiness-related accidents
- Increased irritability
If you or someone you know works nights, early mornings, or rotating shifts and experiences either excessive sleepiness or insomnia you should speak to your doctor. A sleep study may be ordered to help your physician determine how to best improve your health.
