It might even trigger adjustments within the mind, in keeping with a brand new report printed in Occupational and Environmental Medication. Researchers from Korea discovered that individuals who frequently 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 group studied 110 well being care staff—a few of whom labored greater than 52 hours per week, which below 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 had been overworked confirmed adjustments in 17 mind areas in comparison with those that labored typical hours. These variations included areas answerable for government capabilities like logical reasoning, in addition to managing feelings.
Lee says the outcomes stunned him—partly as a result of they counsel that the mind adjustments in response to emphasize and anxiousness, with some potential destructive 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 sudden,” he wrote in an e mail to TIME. “Our outcomes counsel a possible neuroadaptive response, that means the mind may initially attempt to compensate for elevated cognitive and emotional calls for. These shocking findings underscore the complexity of how the mind responds to extended occupational stress.”
Advances in mind imaging now make it attainable to detect even small quantity variations, Lee says. “These technological breakthroughs have empowered researchers to discover beforehand invisible organic adjustments induced by extended stress or extreme workloads, thus opening up a wholly new dimension in occupational and environmental well being analysis.”

The adjustments his group recognized contain areas of the mind which can be answerable for issues like reminiscence, decision-making, consideration, planning, and downside fixing. “Adjustments right here may influence an individual’s capacity to effectively handle duties, make choices, and keep focus,” he says.
Variations in different areas may have an effect on how nicely individuals regulate feelings; the adjustments they noticed could point out much less emotional stability, elevated anxiousness, and issues deciphering emotional cues or managing interpersonal connections.
Would decreasing workload alleviate or reverse a few of these adjustments? It is too quickly to know if these alterations are everlasting, Lee says. “Longitudinal research might be important to grasp if these mind structural adjustments are reversible or persist long-term.” He plans to comply with up this examine with long run information and bigger populations to find out what occurs to those mind adjustments over time, and whether or not adjusting workloads can cut back or reverse them.
Within the meantime, there are issues individuals can do to alleviate a few of the destructive results of overwork on their well being, even when they can not modify their hours. Getting sufficient sleep and bodily exercise, in addition to addressing stress with mindfulness or leisure methods, may help. However Lee says the burden shouldn’t relaxation completely on staff. Companies ought to restrict extreme working hours, present stress-management assets, and promote work-life stability “to guard their staff’ long-term mind well being and productiveness.”
