20. SWSD Associated health risks
• Circadian rhythm sleep disorders (CRSD) are a family
of sleep disorders which affect the timing of sleep
• insomnia
• night workers have an increased incidence of heart disease,
digestive disorders.
• Study:There have been many studies suggesting health
risks associated with shift work. For example, a 2007 study
led by the IARC (International Agency for Research on
Cancer) showed that shiftwork has been associated with
cancer.
• mental disorders like depression or other mood issues
25. • Prescribed sleep/wake scheduling
Experts agree that there is no such thing as an "ideal" night work
schedule, but some schedules may be better than others.
• Bright light treatment
The light-dark cycle is the most important environmental time
cue for entraining circadian rhythms of most species,
including humans, and bright artificial light exposure has
been developed as a method to improve circadian
adaptation in night workers.
• Melatonin treatment
Melatonin is a hormone secreted by the pineal gland in
darkness, normally at night. Its production is suppressed by
light exposure,[25] principally blue light around 460 to
480 nm. Light restriction, or dark therapy, in the hours
before bedtime allows its production.
26. • Medications that promote alertness
Caffeine is the most widely used alerting drug in the world
and has been shown to improve alertness in simulated
night work.[27] Caffeine and naps before a night shift
reduces sleepiness during the shift.
