Do you wake in the morning feeling unrested? Or do you or a loved one snore loudly each night? If you answered yes to these questions, there is a chance you are suffering from a common sleep condition that can be detrimental to your overall health but often remains undiagnosed. Sleep apnea is a condition that causes patients to stop breathing for a short time because the tongue blocks the airway, causing obstruction. Each time you stop breathing, due to lack of oxygen, your brain is alerted to the disruption, causing you to wake.
