The pursuit of success often leads many to extend their working hours, but this seemingly industrious habit might come at a significant health cost. Neurologist Dr. Sudhir Kumar sheds light on the risks associated with prolonged work weeks, using scientific research to highlight how overworking can elevate the chances of stroke and heart disease. According to his insights shared on July 15, the optimal workweek spans 35 to 40 hours, beyond which health risks grow substantially.
Dr. Kumar underscores that working 55 hours or more each week is linked to a heightened cardiovascular risk. Specifically, he notes that individuals who exceed the 35–40 hour threshold face a 35% greater risk of stroke and a 17% increased risk of ischemic heart disease. In support of these findings, he references data from the World Health Organization and the International Labour Organization, which estimate that in 2016, about 745,000 global deaths were attributed to long working hours, primarily due to stroke and heart disease.
The repercussions of extended work hours extend beyond heart health. Dr. Kumar points out that excessive working hours can lead to poor sleep quality, fatigue, burnout, anxiety, and depression. Additionally, such habits may contribute to higher blood pressure, diminished productivity and concentration, increased workplace injuries and errors, and less time for physical activity, nutritious eating, and family interactions.
However, Dr. Kumar stresses that the solution isn’t merely working less, but rather optimizing productivity and recovery. To maintain a healthy balance between work and life, he advises aiming for a 35–40 hour workweek whenever feasible and avoiding regular 55-hour work weeks. He also recommends incorporating regular movement breaks, ensuring 7–9 hours of sleep nightly, engaging in regular exercise, and reserving at least one day each week for personal life and recovery.
Dr. Kumar encapsulates his guidance with the metaphor that “success is a marathon, not a sprint,” emphasizing that safeguarding one’s health is a crucial investment in a long and fruitful career.
