Your Guide to Healthy Sleep, a 72 page booklet, is published by the National Heart, Lung and Blood Institute, part of the National Institutes of Health, which is under the U.S. Department of Health & Human Services.
Recognizing the importance of sleep to good health, and particularly good heart health, this guide provides steps and advice on how to improve your sleep, and thereby improve your health.
During sleep you experience a dip in blood pressure. According to this guide:
“If you don’t get enough sleep, this nightly dip in blood pressure, which appears to be important for good cardiovascular health, may not occur. According to several studies, if your blood pressure does not dip during sleep, you are more likely to experience strokes, chest pain known as angina, an irregular heartbeat, and heart attacks. You are also more likely to develop congestive heart failure, a condition in which fluid builds up in the body because the heart is not pumping sufficiently. Failure to experience the normal dip in blood pressure during sleep can be related to insufficient sleep time, an untreated sleep disorder, or other factors.”
