It might even trigger modifications within the mind, in line with a brand new report printed in Occupational and Environmental Medication. Researchers from Korea discovered that individuals who recurrently work lengthy hours had important mind variations in comparison with individuals who labored much less.
Wanhyung Lee, from the division of preventive medication at Chung-Ang College in Seoul, and his crew studied 110 well being care staff—a few of whom labored greater than 52 hours per week, which beneath Korean regulation constitutes overwork, and a few of whom labored much less. All had MRIs that allowed the scientists to research variations within the quantity and focus of sure mind tissues.
Individuals who have been overworked confirmed modifications in 17 mind areas in comparison with those that labored typical hours. These variations included areas answerable for government features like logical reasoning, in addition to managing feelings.
Lee says the outcomes stunned him—partly as a result of they counsel that the mind modifications in response to emphasize and nervousness, with some potential unfavorable penalties. “We anticipated that extended stress from overwork would have an effect on mind construction, however discovering elevated quantity in sure mind areas was considerably surprising,” he wrote in an electronic mail to TIME. “Our outcomes counsel a possible neuroadaptive response, that means the mind would possibly initially attempt to compensate for elevated cognitive and emotional calls for.

Within the meantime, there are issues individuals can do to alleviate among the unfavorable results of overwork on their well being, even when they cannot regulate their hours.
