A study said sleeping less than six hours or waking up several times in the night is associated with an increased risk of asymptomatic atherosclerosis, which silently hardens and narrows arteries.
Study author said failure to get enough sleep and restlessness during the night should be considered risk factors for blocking or narrowing of the arteries.
The research also showed that people who had short or disrupted sleep were also more likely to have metabolic syndrome, which refers to the combination of diabetes, high blood pressure, and obesity, and depicts an unhealthy lifestyle.
