In recent discussions around work-life balance, neurologist Dr. Sudhir Kumar highlighted the potential health risks associated with long working hours. In a statement shared on July 15, Dr. Kumar elaborated on research findings that suggest a workweek of 35-40 hours is most conducive to maintaining good health. Exceeding this range, particularly working 55 hours or more, has been linked to a notable increase in cardiovascular issues, including a 35% higher risk of stroke and a 17% greater chance of developing ischemic heart disease.
Dr. Kumar pointed to data from the World Health Organization (WHO) and the International Labour Organization (ILO), which estimated that prolonged working hours contributed to approximately 745,000 deaths worldwide in 2016 due to stroke and heart disease. Besides cardiovascular risks, extensive working hours are also associated with poor sleep quality, heightened fatigue, burnout, and mental health issues such as anxiety and depression. Additional consequences include increased blood pressure, reduced productivity, and less time allocated for exercise, healthy eating, and family engagements.
While Dr. Kumar stresses the importance of managing work hours, he clarifies that the objective should not merely be to reduce hours indiscriminately but to optimize work efficiency and recuperation. He advocates for strategies that can help maintain both health and productivity, such as aiming to work within the 35-40 hour range whenever feasible and avoiding regular schedules that exceed 55 hours per week. Regular breaks for movement during the workday, ensuring 7-9 hours of sleep each night, and maintaining a consistent exercise routine are also recommended.
To foster a sustainable work-life balance, Dr. Kumar suggests dedicating at least one day per week for personal recovery and family time. Emphasizing a strategic approach to work, he remarked, “Success is a marathon, not a sprint. Protecting your health is one of the best investments you can make in a long, productive career.” This perspective underscores the notion that safeguarding one’s health is crucial for enduring professional success and overall well-being.
