Adults who slept five or fewer hours a day had 50% more calcium in their coronary arteries than those who slept seven hours a day.

For the study, researchers analyzed more than 47,000 young and middle-aged adults who completed a sleep questionnaire and had advanced tests to detect early coronary artery lesions and measure arterial stiffness.
The findings suggested that adults who slept five or fewer hours a day had 50% more calcium in their coronary arteries than those who slept seven hours a day, while people who slept nine or more hours a day had more than 70% more coronary calcium compared to those who sleep seven hours. Adults who reported poor sleep quality had more than 20% more coronary calcium than those who reported good sleep quality.
Study co-lead author Yoosoo Chang, associate professor at Kangbuk Samsun Hospital in South Korea, said, "We also observed a similar pattern when we measured arterial stiffness. Adults with poor sleep quality have stiffer arteries than those who sleep seven hours a day or had good sleep quality. Overall, we saw the lowest levels of vascular disease in adults sleeping seven hours a day and reporting good sleep quality."
The study was published in Arteriosclerosis, Thrombosis and Vascular Biology.
