the American Heart Association has announced that Sleep duration and sleep disorders may be risk factors for cardiometabolic and cardiovascular disease.

Researchers have conducted a literature review of studies related to sleep duration and disorders and cardiovascular and cardiometabolic disease.

Their results were published online September 19, 2016 in Circulation.

According to population-based studies, they write, obstructive sleep apnea and insomnia put people at significant risk of CVD and cerebrovascular diseases, including arrhythmias, atherosclerosis, coronary heart disease, heart failure, hypertension, and stroke, as well as metabolic diseases such as obesity, type 2 diabetes, and dyslipidemia.

They defined inadequate sleep as less than 7 hours a night. However, long sleep duration, defined as 9 or more hours a night, has also been linked to obesity, hypertension, and diabetes.

Cardiologists are advised to tell their patients not to take sleep lightly and to make sure they allow for sufficient time in bed, in order to obtain at least 7 hours of sleep per night.
