A recent study published in Occupational and Environmental Medicine reveals that working long hours is linked to significant brain changes. Researchers from Korea focused on health care workers, notably those working over 52 hours a week. MRI analysis showed alterations in 17 brain regions compared to those who worked standard hours. These changes affected areas linked to executive function and emotion management. Despite initial expectations around decreased brain function due to stress, findings revealed increased volume in certain regions, hinting at a neuroadaptive response to cognitive demands, emphasizing the complexity of brain changes due to prolonged stress.
Researchers found that individuals working over 52 hours a week exhibited significant brain changes, affecting areas responsible for cognition and emotional management.
The study, noting brain changes in 17 regions, emphasizes the complex neuroadaptive responses to occupational stress, highlighting unexpected increases in some brain areas.
