Obstructive sleep apnea (OSA) is a common disorder where the sufferer stops breathing several times during the night due to laxity of the upper respiratory muscles closing off the airway, causing them to rouse and get inadequate and poor quality sleep. They experience daytime somnolence, headaches, difficulty concentrating, fatigue and have a higher risk of developing such conditions as cardiovascular and cerebrovascular disease. OSA is diagnosed with sleep studies when brain waves are recorded and analyzed as the person sleeps and often requires sleeping with a machine that keeps the airway open. Many people remain undiagnosed as they readily accept the symptoms or self medicate with sleeping pills.
