Grim dawn checklist3/31/2023 ![]() More than 2,000 participants were recruited between 20 from Minnesota, Maryland, Illinois, North Carolina, California and New York state.ĭuring sleep assessments conducted between 20, participants kept a sleep diary over seven consecutive days and wore a wristwatch that tracked their sleep and wake history. The authors set out to learn more about this relationship by analyzing the sleep of older adults - age 69 on average - who participated in the Multi-Ethnic Study of Atherosclerosis, a longitudinal cohort study designed to investigate the prevalence and progression of, and risk factors for, cardiovascular disease. Sleep regularity, the new study's authors defined, is estimated by variations in sleep duration (how long someone sleeps each night) and sleep timing (the time when someone falls asleep nightly) - the fewer variations the better. Poor sleep - including poor quality, abnormal quantity and fragmented sleep - has been linked with cardiovascular disease and cardiovascular disease-related deaths before, but less had been known about the specific associations between sleep regularity and atherosclerosis. ![]() Atherosclerosis can lead to cardiovascular health conditions, including coronary heart disease, angina, heart attacks, strokes and carotid or peripheral artery disease. As plaque accumulates, blood vessel walls thicken, which reduces blood flow and therefore diminishes the amount of oxygen and other nutrients reaching the rest of the body. This plaque is made up of cholesterol, fatty substances, cellular waste products, calcium and fibrin, a clotting agent in the blood. "This study is one of the first investigations to provide evidence of a connection between irregular sleep duration and irregular sleep timing and atherosclerosis," said lead study author Kelsie Full, an assistant professor of medicine in the epidemiology division at Vanderbilt University Medical Center in Nashville.Ītherosclerosis is the buildup of plaque in arteries, according to the American Heart Association. ![]() But in the background, irregular and poor-quality sleeping patterns could increase your risk for developing cardiovascular disease, according to a study published this week in the Journal of the American Heart Association. When you don't get enough good sleep, the short-term consequences are noticeable - maybe you're distracted at work or snappy with loved ones. ![]()
