In the pursuit of career success, many might find themselves working long hours, yet this strategy could have serious health implications. Neurologist Dr. Sudhir Kumar recently addressed this issue, highlighting the potential dangers of overworking and offering insights into maintaining a healthier work-life balance. In a post shared on X on July 15, Dr. Kumar discussed scientific findings regarding the optimal number of work hours per week and the associated health risks of exceeding these limits, particularly the increased likelihood of stroke and heart disease.
Dr. Kumar cited research indicating that working between 35 and 40 hours a week is generally the healthiest range. Exceeding this, particularly working 55 hours or more, is linked to a notably higher risk of cardiovascular issues. Specifically, individuals who work 55 or more hours weekly face a 35% increased risk of stroke and a 17% higher risk of ischaemic heart disease compared to those who work within the healthier range. He also referenced data from the World Health Organization (WHO) and the International Labour Organization (ILO), which estimated that prolonged work hours contributed to approximately 745,000 deaths globally in 2016 due to stroke and heart disease.
Beyond cardiovascular health, Dr. Kumar pointed out additional negative effects of long work hours, such as poor sleep quality, increased fatigue, burnout, anxiety, and depression. He noted that these conditions can lead to higher blood pressure, diminished productivity and concentration, and more frequent workplace injuries and errors. Furthermore, overworking often results in reduced time for exercise, healthy eating, and family life, thereby impacting overall well-being.
However, Dr. Kumar stressed that achieving a healthy work-life balance doesn’t mean merely reducing work hours. Instead, he advocated for working smarter and prioritizing recovery. To balance health and productivity effectively, he recommended maintaining a work schedule of 35-40 hours per week when possible, avoiding regular workweeks of 55 hours or more, taking regular breaks to move during the day, ensuring 7-9 hours of sleep each night, and engaging in regular exercise. He also advised dedicating at least one day per week to rest and personal activities.
Concluding his advice, Dr. Kumar emphasized the importance of viewing career success as a long-term endeavor. “Success is a marathon, not a sprint,” he remarked, underscoring that safeguarding one’s health is a crucial investment in sustaining a long and productive career.
