If you snore, have trouble falling asleep, or tend to wake up groggy and tired, a new study suggests that your health may be at risk.

Published on December 1 in the journal Sleep, researchers discovered a connection between snoring and restless sleep to higher risks of metabolic syndrome, which is a group of risk factors for heart disease, stroke and diabetes, defined as having at least three of the following: too much abdominal fat, high triglycerides, low HDL (good) cholesterol, high blood pressure, and high blood sugar.
