Study on changes in brain structure in overworked healthcare workers
A recent study conducted by researchers from South Korea's Chung-Ang University has identified structural changes in the brains of healthcare workers who engage in excessive working hours, specifically those exceeding 52 hours per week. The study observed alterations in regions associated with executive function and emotional regulation, such as the middle frontal gyrus, insula, and superior temporal gyrus. While these findings suggest a link between overwork and changes in brain structure, the researchers emphasized the preliminary nature of the study and cautioned against drawing definitive conclusions without further longitudinal research. Dr. Rebekah Hoffman, Chair of Royal Australian College of General Practitioners NSW&ACT, noted the ambiguity of these changes, questioning whether they represent adaptive enhancements or potential detriments to long-term health. The study underscores the need for policies aimed at mitigating excessive working hours to safeguard the well-being of healthcare professionals.
