MoreIf you usually wake up groggy and grumpy, you’re probably not getting enough sleep. Improving Sleep: A guide to a good night’s rest, a newly updated report from Harvard Medical School, explains how lack of sleep does more than make you bleary—it can put you at risk for heart disease, diabetes, obesity, and other health problems, according to a recent press release.
For some people, late-night TV watching or Web surfing is to blame. But for many others, the culprit is insomnia (trouble falling or staying asleep) or sleep apnea, a condition in which the airway closes and breathing stops or becomes shallower hundreds of times each night. It causes relentless daytime fatigue that may lead to failed careers, broken marriages, and automobile and workplace accidents.
Sleep apnea can also wreak havoc on the cardiovascular system, because the heart must work harder every time the brain sends out a "wake up and breathe" signal. People with sleep apnea are prone to high blood pressure, heart failure, and stroke. Although more than half of the estimated 18 million American who have sleep apnea are overweight, many are not. The disorder affects about one in 25 middle-aged men and one in 50 middle-aged women. By age 65, about one in 10 people has the problem.
