Key result
Sleeping <6 hours per night in shift workers was associated with higher systolic blood pressure (141.07 vs 133.50 mmHg) and high rates of physical fatigue (60%) and hypertension (40%).
Why the study?
The utility of the sobriety test as a tool for measuring physical fatigue and hypertension in shift workers with varying sleep duration needed evaluation.
Does shorter sleep duration (< 6 hours per night) increase physical fatigue (measured by the sobriety test) and blood pressure/hypertension in industrial shift workers?
Cross-Sectional (n=50)
No

Among industrial shift workers, sleeping less than 6 hours per night is associated with higher physical fatigue as measured by a sobriety test and elevated systolic and diastolic blood pressure.
Purpose: This study evaluated the sobriety test as a tool for measuring physical fatigue and hypertension in shift workers at PT. Maggala Alam Lesari, with a focus on sleep duration. Research methodology: A descriptive quantitative study with a cross-sectional design was conducted with 50 shift workers selected through purposive sampling. The Sobriety test assessed physical fatigue, and blood pressure measurements identified hypertension. A sleep duration questionnaire was used to explore its impact on fatigue and hypertension. Results: Of the 50 workers, 32 (65%) reported sleeping < 6 h per night, correlating with higher levels of physical fatigue. The average SBP of workers sleeping < 6 h per night was 141. mmHg (SD = 6.5), while those sleeping > 6 h per night had an average SBP of 133. mmHg (SD = 5.2). Forty percent of the participants were diagnosed with hypertension, with the majority reporting inadequate sleep. Conclusions: The sobriety test effectively measured physical fatigue among shift workers. Shorter sleep duration was associated with higher levels of fatigue and increased hypertension, which could elevate the risk of cardiovascular diseases. Improving sleep quality is a critical intervention to enhance the health and well-being of shift workers. Limitations: The cross-sectional design of the study limits the causal conclusions, and the sample size may not be fully representative. Contributions: This study emphasizes the importance of sleep-in managing fatigue and hypertension, and provides insights for improving worker health.

Fernando et al. (2026) conducted a cross-sectional in Physical fatigue and hypertension in shift workers (n=50). Short sleep duration (<6 hours per night) vs. Sleep duration >6 hours per night was evaluated on Systolic blood pressure (mmHg). Sleeping <6 hours per night in shift workers was associated with higher systolic blood pressure (141.07 vs 133.50 mmHg) and high rates of physical fatigue (60%) and hypertension (40%).
