Sleep matters: Duration, timing, quality and more may affect cardiovascular disease risk

Healthy sleep includes multiple components, such as number of hours of sleep per night, how long it takes to fall asleep, daytime functioning and self-reported sleep satisfaction, and addressing these different dimensions of sleep may help to reduce cardiometabolic health and related risk factors, according to a new American Heart Association scientific statement published today in Circulation: Cardiovascular Quality and Outcomes. The new scientific statement, "Multidimensional Sleep Health: Definitions and Implications for Cardiometabolic Health," describes multiple components of sleep health, such as sleep duration, continuity, timing, satisfaction, regularity and daytime functioning.

The scientific statement also reviews the latest evidence on what is known about the relationship between sleep and various cardiometabolic health factors, including body fat, blood sugar, cholesterol and blood pressure, and how healthy sleep positively impacts physical health and mental well-being. "Most adults need 7 to 9 hours of sleep each night, and suboptimal sleep raises the risk for cardiovascular disease, along with risk of cognitive decline, depression, obesity, as well as high blood pressure, blood sugar and cholesterol levels," said Chair of the scientific statement writing group Marie-Pierre St-Onge, Ph.D., C.C.S.H., FAHA, an associate professor of nutritional medicine in the department of medicine and director of the Center of Excellence for Sleep & Circadian Research, both at Columbia University Irving Medical Center in New York City.
