Background of the Study
Shift work, particularly night shifts, is a common work arrangement in industries such as healthcare, security, manufacturing, and customer service. While night shifts help organizations maintain 24-hour operations, they often disrupt employees' natural sleep patterns, leading to poor sleep quality and reduced productivity (Abubakar & Salisu, 2023). Studies have shown that night shift workers are more likely to suffer from sleep deprivation, fatigue, and cognitive impairment, all of which affect job performance and overall well-being (Olawale & Bello, 2024).
In Katsina State, industries such as healthcare, transportation, and security services rely on night shifts to maintain continuous operations. However, workers who frequently engage in night shifts may experience difficulty maintaining healthy sleep patterns, leading to long-term health complications such as insomnia, cardiovascular issues, and decreased work efficiency. Additionally, sleep disturbances among night shift workers can increase workplace errors, absenteeism, and overall job dissatisfaction.
This study aims to investigate the impact of night shifts on sleep quality and productivity among workers in Katsina State. By identifying key challenges associated with night shift work, the study will provide recommendations for improving employee well-being and optimizing shift work structures.
Statement of the Problem
Night shift work significantly alters the body's natural circadian rhythm, leading to sleep disturbances and decreased alertness. Many night shift workers in Katsina State struggle with poor sleep quality, which affects their productivity and increases the risk of workplace accidents. Additionally, prolonged night shift work can lead to chronic health problems, impacting employees' long-term job performance and career longevity.
Despite the importance of night shift work in various industries, there is limited research on how it affects workers’ sleep quality and productivity in Katsina State. This study seeks to bridge this gap by assessing the extent of sleep disturbances among night shift workers and evaluating how these disturbances influence work efficiency and overall job performance.
Objectives of the Study
1. To examine the effect of night shifts on sleep quality among workers in Katsina State.
2. To evaluate the relationship between sleep quality and productivity among night shift workers.
3. To recommend strategies for improving sleep quality and productivity in night shift work environments.
Research Questions
1. How do night shifts affect sleep quality among workers in Katsina State?
2. What is the relationship between sleep quality and productivity in night shift workers?
3. What strategies can be implemented to enhance sleep quality and productivity among night shift workers?
Research Hypotheses
1. Night shift work significantly reduces sleep quality among employees.
2. Poor sleep quality negatively affects productivity among night shift workers.
3. Implementing sleep management strategies improves productivity and well-being among night shift workers.
Scope and Limitations of the Study
The study will focus on night shift workers across different industries in Katsina State, including healthcare, security, and manufacturing. Limitations may include variations in individual sleep patterns and difficulty in obtaining accurate self-reported sleep quality data.
