Having a high-status job might look great on paper, but recent research indicates that it could also inflate one’s ego—though not in a flattering way.
Findings from a study in Korea highlight that extensive work hours could lead to serious cognitive issues.
This study, featured in the journal Work and Environmental Medicine, reveals that consistently working over 52 hours weekly correlates with notable changes in brain structure, including a striking 19% increase in volume in certain areas.
While that might sound impressive—or like the premise of a Hollywood film—it’s actually concerning.
Utilizing brain imaging, researchers found that medical professionals who worked excessive hours exhibited thickening in parts of the brain associated with emotional control and decision-making.
This thickening is a response from the brain due to chronic stress and overwork, which can pave the way for burnout, anxiety, depression, and other mental health issues in the long run.
“This study provides new evidence that overwork is linked to structural brain changes, especially in areas tied to executive functioning and emotional regulation,” the researchers noted.
They further emphasized that working long hours may induce neurological changes that could impact cognitive and emotional well-being.
It’s not new information that extended work hours can lead to various health problems.
A 2021 report found that exceeding 55 hours in a week heightens the risk of stroke and heart disease.
Moreover, a 2018 survey indicated that working more than 45 hours weekly significantly increased diabetes risk in women, while the same did not apply to men.
Just last year, a 35-year-old investment banker named Leorkenas III stirred controversy for clocking in 100-hour workweeks on Wall Street.
Experts have long contended that such work schedules can lead to sleep deprivation and chronic stress, resulting in accelerated aging, skin issues, visual impairments, heart complications, weight gain, musculoskeletal pain, digestive problems, a weakened immune system, and mental health challenges.
