Core Viewpoint - The article discusses the impact of long working hours on brain structure, particularly in relation to emotional regulation and executive function, highlighting the need for workplace policies to reduce excessive working hours [2][10]. Group 1: Research Findings - A study published in Occupational & Environmental Medicine indicates that working over 52 hours per week may alter brain structures associated with emotional regulation and executive function, potentially affecting cognitive abilities such as working memory and problem-solving [3][10]. - The research involved a cohort of 110 healthcare professionals, comparing those who worked over 52 hours weekly with those who adhered to standard working hours, revealing significant structural changes in the brains of those with longer hours [4][5]. - Specifically, the middle frontal gyrus, crucial for various cognitive functions, showed a 19% increase in volume among those working longer hours, alongside notable changes in 17 other brain regions related to attention, planning, and decision-making [5][9]. Group 2: Implications and Future Research - The observed increase in brain volume among overworked individuals may reflect a neuroadaptive response to chronic occupational stress, although the exact mechanisms remain speculative [9][10]. - The study emphasizes the importance of addressing overwork as a significant occupational health issue and advocates for the development of workplace policies aimed at reducing excessive working hours [10].
