Working long hours can pose an insidious threat to health, as the World Health Organization (WHO) reports that it led to 745,000 deaths from heart disease and stroke in just one year.
While research links overwork with poor health outcomes, the underlying biological mechanisms are unclear. However, a recent study may shed light on them, as it found that working long hours was associated with an increased size of various brain regions. This may be responsible for the cognitive and emotional challenges that frequently come with working well beyond 40 hours per week.
