Sleeping less than 7 hours can lead to heart disease

Researchers tested sedentary, middle-aged adults without heart disease then they were asked to complete a questionnaire designed to accurately estimate average nightly sleep and a small amount of blood was taken from each subject after an overnight fast.

Jamie Hijmans, one of the authors of the study, said: "The link between insufficient sleep and cardiovascular disease may be due to, in part, changes in microRNAs. These findings suggest there may be a "fingerprint" associated with a person's sleep habits, and that fluctuations in microRNA levels may serve as a warning or guide to disease stage and progression."
