The study showed that those who slept for less than six hours a night were 27 per cent more likely to have subclinical atherosclerosis than those who slept for an average of seven or eight hours a night.

Interestingly, those who sleep more than 8 hours a night also have an increased risk.
People who sleep less than seven hours a night also have an increased risk of heart disease, and this is true regardless of other factors that influence heart health, like age, weight, smoking and exercise habits. Not sleeping enough can also increase heart-related issues such as blood pressure and obesity.
