Past studies have examined the link between sleep and stroke, but that research has focused mainly on people with sleep apnea, a disorder that causes interruptions in breathing or shallow breaths during sleep. In one study involving patients with severe sleep apnea (five or more episodes of apnea per hour), researchers found it was "significantly related to a two-fold increased risk of a stroke," says Bernadette Boden-Albala, lead author of the current study and assistant professor of neurology at Columbia University's College of Physicians and Surgeons...
...type of sleep disturbances these people were having." While the scale indicates that people are sleepy during the day and therefore not resting well at night, it doesn't say why. In terms of stroke and other vascular risks, says Boden-Albala, "The question really is, Is it sleep apnea or is it the physiological consequence of not getting enough sleep...
...preponderance of evidence would suggest that it's sleep apnea, which is known to cause severe blood-pressure variations. But, according to Boden-Albala, a growing body of research, including her own past work, suggests that sleep deprivation is linked to a variety of conditions, such as obesity, diabetes and hypertension, that may also contribute to vascular risk. "There's more to it than just sleep apnea but we need to figure out why," says Boden-Albala...
...five American children between the ages of 6 and 11 are overweight. Perhaps that statistic doesn’t resound as much as it should—it means that nearly one in five children today are already on track for developing type 2 diabetes, hypertension, cardiovascular disease, sleep apnea, and the whole glut of diseases and disorders associated with obesity. If America’s dire obesity epidemic is to be contained, decisive action must be taken in the interest of the public health, starting with policies that encourage children and adolescents to develop healthy habits that will last...
...failure of the fat person's will, the fact is, it works. Studies have shown that after surgery, patients often lose 50% or more of their excess weight - and keep it off - and symptoms of obesity-related conditions like diabetes, high blood pressure, high cholesterol and sleep apnea are improved or eliminated altogether. Now, two new studies in the New England Journal of Medicine (NEJM) show another long-term benefit: a lower risk of death...
