Consequences

What are the consequences of Shift Work Disorder?

Shift work disrupts both the individual’s sleep and wakeful experiences,89 90 and shift work (even without the disorder) is disruptive to one’s health. Shift workers in general are at an increased risk for peptic ulcer, coronary heart disease, insulin resistance, the metabolic syndrome, and respiratory infections.91 92  
Those who have been diagnosed with Shift Work Disorder experience a higher rate of sleepiness-related accidents, absenteeism, depression, reduced social and family activities, and higher morbidity, compared to shift workers without such a diagnosis.93 94
