Summary
Fixed 12-hour night and day shifts impact worker fatigue and workability. While night shifts may not inherently be a health issue, lifestyle factors and sleep difficulties influence fatigue, and job longevity decreases workability.
Area of Science:
- Occupational Health
- Industrial Psychology
- Human Factors Engineering
Context:
- Investigating the effects of extended work shifts in industrial settings.
- Analyzing the interplay between shift work schedules and worker well-being.
Purpose:
- To examine factors influencing fatigue perception and workability in workers on 12-hour fixed night and day shifts.
- To identify protective and risk factors associated with shift work.
Summary:
- A cross-sectional study of 43 textile factory workers revealed that lifestyle factors like physical activity can mitigate fatigue, while sleep difficulties exacerbate it.
- Workability was linked to job longevity, decreasing with more years on the job, and interestingly, night shifts showed a higher workability index.
- The 12-hour shift structure appears to increase workload, impacting fatigue, workability, and sleep quality.
Impact:
- Findings suggest night shifts may not universally pose health risks, but highlight the need for further research.
- Identifies a decline in workability with job longevity, necessitating longitudinal studies.
- Provides insights for optimizing shift work schedules and mitigating negative health outcomes in industrial workers.
