Shift work sleep disorder (SWSD) affects workers with non-traditional schedules. Shift work sleep disorder involves circadian misalignment between work demands and natural sleep timing. Common in healthcare, transportation, public safety, and other industries.
Symptoms
- Insomnia when trying to sleep during day
- Excessive sleepiness during work hours
- Reduced total sleep time
- Fatigue, mood changes
- Cognitive impairment during shifts
- GI symptoms common
Health risks
Long-term shift work associated with:
- Cardiovascular disease
- Type 2 diabetes
- Some cancers (WHO classifies as probable carcinogen)
- Mental health issues
- Accidents (workplace and driving)
Strategies for night shift workers
Sleep environment:
- Blackout curtains
- White noise/earplugs
- Cool temperature
- Phone on silent
- Family awareness
Scheduling:
- Anchor sleep period (consistent block)
- Strategic naps before shifts
- Maintain similar schedule on days off when possible
Light management:
- Bright light during shift to maintain alertness
- Sunglasses on commute home (block morning light)
- Dark sleep environment
Pharmacological options
For sleepiness during work:
- Modafinil (Provigil) — FDA approved for SWSD
- Armodafinil (Nuvigil)
- Caffeine strategically
For sleep:
- Melatonin before sleep
- Sleep medications carefully
Workplace strategies
- Forward-rotating shifts (day → evening → night) better than reverse
- Adequate days off between shift types
- Limited consecutive nights
- Strategic napping during shifts (when safe)
