If your schedule robs you of slumber, you may be setting yourself up for diabetes.But don’t press the snooze bar too many times, because oversleeping might bring the same result.Those are the surprising findings of a new study that suggests too little or too much sleep could lead to the blood sugar disease, at least in older people."This is one additional piece of information bolstering the common recommendation for sleeping seven to eight hours a night,” said study co-author Dr. Daniel Gottlieb, an associate professor of medicine at Boston University.Gottlieb and his colleagues examined statistics on the health of 1,486 participants in a 1995-1998 study that studied the cardiovascular effects of sleep disorders that affect breathing. The participants were aged 53-93.The goal of the researchers was to see if they could find a link between sleep levels and impaired ability to process glucose, a hallmark of diabetes. They report their findings in this week’s issue of the Archives of Internal Medicine.
