Shiftwork; Sleep loss; alertness
The study found that shift workers at remote mining operations experience shorter sleep duration, reduced alertness, and a higher risk for sleep disorders.
Shift workers employed at a remote mining operation may experience sleep loss, impaired alertness, and consequently negative health and safety outcomes. This study determined the sleep behaviors and prevalence of risk for sleep disorders among shift workers; and quantified alertness for a roster cycle. Sleep duration was significantly less following; night shift by 77 +/- 7 min and day shift by 30 +/- 7 min. The wake after sleep onset was less by 23 +/- 3 min for night shifts and 22 +/- 3 min for day shifts (p < 0.05 for all). The prevalence of risk for sleep apnea was 31%, insomnia was 8%, and shiftwork disorder was 44%. Average alertness for all working hours was 75%. Shiftwork in remote mining operations is a significant factor that leads to sleep loss and reduced alertness, which is exacerbated by the high prevalence of risk for sleep disorders.
