A study of adults in Taiwan shows that reporting a long sleep duration of more than eight hours per night was associated with a higher risk of increased arterial stiffness in men. A self-reported short sleep duration of less than six hours per night was not associated with a significant risk of increased arterial stiffness in men or women.

According to a commentary on the study, the data could help inform community-based interventions to reduce cardiovascular disease in other populations, particularly African-Americans.
