Circadian Rhythm Disruption Due to Chronic Sleep Deprivation and Its Impact on Productivity and Quality of Life Among Healthcare Workers

Abstract

Circadian rhythm disruption resulting from chronic sleep deprivation has become a growing occupational health concern among healthcare workers, particularly those engaged in night shifts and rotating work schedules. While continuous healthcare delivery requires around-the-clock staffing, misalignment between biological rhythms and work demands can have profound consequences on workers’ physical health, mental well-being, productivity, and overall quality of life. This paper examines the physiological mechanisms underlying circadian rhythm disruption, explores its impact on healthcare workers’ productivity and professional performance, and analyzes its broader effects on quality of life, including psychological health, social functioning, and work–life balance. Drawing on international empirical evidence, the paper also discusses organizational challenges and highlights evidence-based strategies aimed at mitigating the adverse effects of sleep–wake cycle disturbances in healthcare settings. Addressing circadian rhythm disruption is essential for sustaining a healthy healthcare workforce, improving care quality, and enhancing healthcare system resilience.
