Correlates to Sleepiness on Night Shift among Male Workers Engaged in Three-shift Work in a Chemical Plant: Its Association with Sleep Practice and Job Stress

Abstract

The purpose of this study was to examine the correlation of sleepiness during night shift (SNS) in male shiftworkers with nonpharmacological self-management (nPSM) practices to facilitate good day sleep, and also with job stress. Sleepiness on the job and possible correlates to SNS among 157 male shiftworkers in a rotating three-shift schedule at a chemical plant were cross-sectionally investigated using a self-administered questionnaire. Multivariate analyses revealed that SNS was positively associated with drinking alcoholic beverages before day sleep, but inversely associated with subjective health status, being of the evening type, abstaining from caffeine before day sleep, having a bath before day sleep, job control, reward from work, feeling suited to the job, and support from colleagues. SNS correlated with certain nPSM practices and also with possible modifiers of job stress. These findings provide clues to developing countermeasures against SNS among shiftworkers. The effects of nPSM practices and job stress management on their day sleep and SNS should be examined in detail.

Insomnia in Shift Work Disorder Relates to Occupational and Neurophysiological Impairment

“…sleepiness, 11,[20][21][22][23][24][25][26][27][28][29] with less regard to shift-work related insomnia. Indeed, most of our knowledge on insomnia and performance is based upon findings in day workers.…”

Impact of Rotating Shifts on Nurse’s Health Working in Public and Private Sector Hospitals of Peshawar

“…Another study suggested that rotating shifts among paramedics cause higher levels of sleepiness and fatigue (24), while our study indicated that rotating shifts cause fatigue (physical impact) and insomnia (psychological impact). The finding of a study shows that the shift workers were associated with a higher prevalence of insomnia (25) and sleepiness during the night shift (26). In this study, the rotating shift nurses reported insomnia and cognitive difficulty as psychological impacts.…”

Chronotype, nursing activity, and gender: A systematic review

“…Similar findings have been reported by various authors (Nielsen, ; Yu, Yun, & Ahn, ). Therefore, increasing social support (Kageyama, Kobayashi, & Abe‐Gotoh, ) and established good lifestyles (i.e., balanced diet and physical activity) should be encouraged, thereby preventing the development of sleep and mood problems.…”
