Long working hours may affect more than your energy and work-life balance. Research has linked regularly working 55 hours or more per week with a higher risk of stroke and death from ischaemic heart disease compared with working 35–40 hours weekly.
The concern is not an occasional busy day, but a repeated pattern of overwork that leaves little time for sleep, exercise and recovery. Health experts say that everyday habits and working conditions both matter when it comes to protecting long-term heart health.
How Can Long Working Hours Put Pressure on the Heart?
Prolonged stress can keep the body’s stress response active, potentially increasing heart rate and blood pressure. Over time, demanding schedules may also disrupt sleep and make it harder to maintain regular physical activity.
Busy routines can encourage other unhealthy patterns, including relying on convenient processed foods, skipping meals or postponing health check-ups. Together, these factors may contribute to cardiovascular risk.
Who Should Be More Careful?
People with high blood pressure, diabetes, high cholesterol or a family history of heart disease may need to pay particular attention to their overall health. However, cardiovascular problems can affect people of different ages, and feeling fit does not eliminate every risk.
The reported figures describe associations across populations, not a prediction that every person working long hours will develop heart disease.
Simple Ways to Protect Your Heart
Building recovery into the workday can help support better health. Practical steps include maintaining a consistent sleep schedule, taking movement breaks, eating balanced meals and making time for regular physical activity.
It is also important to monitor blood pressure and seek medical advice when needed. Persistent fatigue or sleep difficulties deserve attention, while chest pain or severe breathlessness requires urgent medical assessment.
A demanding career does not have to mean neglecting health. Sustainable work routines, adequate rest and preventive healthcare can help people look after their wellbeing while managing professional responsibilities.
