“People working evening, night, or rotating shifts have a slightly higher risk of heart disease . Research on long work hours (overtime work) point to a wide variety of health effects, including increases in work accidents and injuries, musculoskeletal disorders, fatigue, psychological symptoms, unhealthy behaviors (such as smoking or alcohol use), cardiovascular risk factors (such as high blood pressure), and CVD [40-43]. Prolonged exposure to work may act to increase fatigue thereby increasing heart disease risk while rest breaks, days off, and vacations all provide relief and lower risk. The stress of returning to work after a weekend off increases risk as increased heart disease deaths have been reported for Mondays compared to other days of the week . Beginning in 1958, research has suggested that long working hours may increase risk of heart disease [45-50]. Much research has been conducted in Asia, beginning with the interest in Japan about Karoshi—“sudden death from overwork” . The impact of overtime on health may be greater for workers in stressful jobs, such as professional drivers , shift workers , and older workers [41, 53].”
