Working lengthy hours comes with a slew of well being points, from an excessive amount of stress to disturbed sleep, coronary heart circumstances, and mental-health problems like anxiousness and melancholy.
It could even trigger adjustments within the mind, based on a brand new report revealed in Occupational and Environmental Drugs. Researchers from Korea discovered that individuals who recurrently work lengthy hours had vital 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 workforce studied 110 well being care staff—a few of whom labored greater than 52 hours every 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 accountable for government features like logical reasoning, in addition to managing feelings.
Lee says the outcomes shocked him—partly as a result of they recommend that the mind adjustments in response to emphasize and anxiousness, with some potential detrimental 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 e-mail to TIME. “Our outcomes recommend a possible neuroadaptive response, that means the mind would possibly initially attempt to compensate for elevated cognitive and emotional calls for. These stunning findings underscore the complexity of how the mind responds to extended occupational stress.”
Advances in mind imaging now make it doable 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 workforce recognized contain areas of the mind which can be accountable for issues like reminiscence, decision-making, consideration, planning, and downside fixing. “Adjustments right here might affect an individual’s capability to effectively handle duties, make choices, and keep focus,” he says.
Variations in different areas might 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 observe up this examine with long run knowledge and bigger populations to find out what occurs to those mind adjustments over time, and whether or not adjusting workloads can scale back or reverse them.
Within the meantime, there are issues individuals can do to alleviate a few of the detrimental results of overwork on their well being, even when they cannot modify their hours. Getting sufficient sleep and bodily exercise, in addition to addressing stress with mindfulness or rest strategies, may help. However Lee says the burden shouldn’t relaxation fully on workers. Companies ought to restrict extreme working hours, present stress-management assets, and promote work-life stability “to guard their workers’ long-term mind well being and productiveness.”
