Most people are suffering from the most common form of Sleep Apnea: Obstructive Sleep Apnea, or OSA. Sleep Apnea is a potentially life-threatening medical disorder that causes your body to stop breathing during sleep. In OSA, the muscles in your throat relax and your tongue or other throat structures fall back and block the airway, reducing the amount of oxygen delivered to your organs, including your heart and brain.
People usually snore loudly. They stop breathing for short periods of time, 10 seconds or more each pause. The breathing pauses during sleep cause your body to briefly wake up while you remain unaware. This can happen hundreds of times in a night, causing you to wake up feeling less than refreshed and to feel tired during the day.
Many people with OSA don’t actually notice the interruptions in their breathing. However, the transition from restful, deep sleep to a light sleep isn’t enough to function well, and sleep apnea sufferers are often very tired during the day, and are prone to headaches and a dry mouth.
