What key factor contributes to the risk of myocardial infarction in workers?

The length of work hours is a key factor that significantly contributes to the risk of myocardial infarction among workers. Extended work hours can lead to increased stress levels, fatigue, and a lack of time for physical activity and healthy eating. Chronic stress from long working hours can elevate blood pressure and contribute to unhealthy behaviors, such as poor diet and reduced exercise, both of which are risk factors for heart disease.

Additionally, longer work hours often correlate with higher rates of job strain and may lead to unhealthy coping mechanisms such as smoking or increased alcohol consumption. This environment raises the likelihood of cardiovascular events, including myocardial infarction. Therefore, the correlation between extended working hours and health outcomes is well-documented and widely recognized in occupational health studies.
