Working long hours appears to be associated with a higher risk of stroke, but the reasons behind this link remain uncertain.
Working up to 48 hours per week increases stroke risk by 10%; working up to 54 hours per week increases stroke risk by 27%; and working over 55 hours per week increases stroke risk by 33% (compared with a standard 35-40 hour week).
