Impact of circadian rhythms on business efficiency and economic growth
Keywords:
circadian rhythms, productivity, economic impacts, shift work, workplace efficiency, public financeAbstract
Because circadian rhythms control key processes such as sleep, cognition and metabolism, their disturbance is now widely viewed as a significant factor reducing worker productivity and influencing economic performance. While biomedical research provides extensive evidence on the health consequences of circadian misalignment, its implications for labour efficiency, organizational outcomes, and public finances remain underexamined in economic literature. This review synthesizes findings from empirical studies published between 2011 and 2025 to assess how sleep disruption, shift work, and chronotype mismatch affect individual performance, workplace efficiency, and broader economic indicators. Results consistently show that circadian misalignment reduces cognitive functioning, increases error rates and absenteeism, and contributes to long-term health risks, including metabolic and cardiovascular disorders. These outcomes impose substantial costs on firms through productivity losses, higher turnover, and increased injury risk, while also generating financial burdens for public healthcare and social insurance systems. The review highlights several evidence-based strategies such as chronotype-aligned scheduling, predictable shift systems, improved lighting conditions, and sleep-hygiene interventions that can mitigate these negative effects. The study concludes by emphasising the economic relevance of integrating circadian science into workplace policies and human resource management practices.
