“…The prevalence rate of cardiovascular symptoms in shift workers was higher than in day workers but the difference was not significant. In contrast to some other studies indicating an association between shift work and cardiovascular disorders [5,6,21], the performed analysis showed that shift work was not associated with the symptoms. This modeling demonstrated that long working hours and job unit were independent risk factors for cardiovascular symptoms.…”

“…Studies suggest that night-shift work contributes to a misalignment between the circadian rhythm and the normal sleep-wake schedule, disturbed physiological rhythms and sleep debt, subsequently resulting in development of a number of symptoms including fatigue and an increased risk of committing errors in the workplace 4,5) . Previous studies in the medical field have shown that nurses working rotating shifts including night shifts are overall less healthy and more frequently make medical errors than day shift nurses not working rotating shifts [6][7][8] .…”

Methods:We conducted a randomized crossover study involving registered nurses at a teaching hospital working a two-shift system including the night shift. Participants were instructed to expose themselves to BL for 10 min on workday mornings. Results: A total of 61 participants were enrolled in the present study. Thirty-one participants received BL exposure in the first month, and the other 30 received it in the second month. Significant improvements were noted in the BL periods compared with the non-BL periods for self-assessed sleepiness at 10:00 on day-shift days evaluated using the Karolinska Sleepiness Scale, self-assessment of night sleep for day-shift days using the Visual Analogue Scale and for fatigue assessed using the Checklist Individual Strength Questionnaire. The estimated mean difference for each scale (95% confidence interval) was -0.55 (-0.91, -0.20), 0.37 (0.04, 0.70) and -2.13 (-3.78, -0.48), respectively. Mean response time evaluated using the psychomotor vigilance task test (PVT) showed significant improvement in the BL periods compared with the non-BL periods. No statistically significant differences were observed for sleepiness at 14:00, depression, number of PVT lapses or frequency of perceived adverse events and near misses. Conclusion: Our findings suggest that brief BL exposure on mornings preceding a day shift is effective in improving sleepiness and performance during day-shift work, subjective nighttime sleep on day-shift days, and perceived fatigue for the preceding two weeks in rapidly rotating shift nurses.

“…Thus, the usual human sleep architecture is the result of millions of years of evolution and any homeostatic functions served by the experience of sleep are likely to be maximized when that neurobiology is expressed as is coded for by our evolutionary history. Shift working miners will by necessity of workplace requirements be constantly performing outside of their normal homeostatic sleep wake drives [35]. Thus, employees who are beginning their shifts with a degree of sleep loss will simultaneously be faced with an increased drive to recover the lost sleep [36].…”

Sleep and Heat Related Changes in the Cognitive Performance of Underground Miners: A Possible Health and Safety Concern

This review describes some of the literature pertaining to sleep deprivation, shift working, and heat exposure. Consequences of each on human cognitive function, particularly with respect to vigilance and attentional capacity are reviewed. Individually, each of these factors is known to impair human cognition; however, we propose the possibility that for miners working in hot underground environments and who are assigned to rotating shifts, the combination may leave miners with significant degrees of fatigue and decreased ability to focus on tasks. We suggest that such decreased capacity for vigilance is a source of concern in an occupational health and safety context.
