What a Good Night’s Sleep Can Do for Your Heart

Brief summary:
“The American Heart Association last month added sleep to its list of factors critical to heart health, a list that includes seven others such as diet, physical activity and blood pressure. The recommendation reflects widening scientific consensus on the role sleep plays in helping prevent heart disease. If you don’t get enough uninterrupted sleep, you are more at risk of developing hypertension, Type 2 diabetes and obesity. In a study of nearly 4,000 middle-aged men and women, researchers found more atherosclerosis, a condition characterized by a buildup of fatty plaques in the arteries, in people who slept fewer than six hours a night than in those who got seven to eight hours. The scientists found increased amounts of plaque and in more locations in the participants whose sleep was most fragmented compared with other study participants.Interruptions during sleep matter too. Poor quality sleep interferes with the body’s normal rest and repair cycles, scientists believe, disrupting its ability to manage inflammation, the body’s natural immune response to injury that is damaging if it becomes chronic. That appears to be true even in people who think they’re getting enough sleep, according to research by a group of scientists at Columbia University.”
