Do you wake each morning after a full night’s sleep and still feel like you didn’t get enough rest? Maybe you’ve heard from a loved one that you frequently snore. If so, you may be experiencing the effects of a common sleep condition that affects nearly a billion people each year — sleep apnea. Sleep apnea is a common condition that causes patients to stop breathing for a short time due to the tongue blocking the airway and causing the obstruction. Each time you stop breathing, due to lack of oxygen, your brain is alerted to the disruption, causing you to wake. This pattern typically continues through the entire sleep period.
