Obstructive Sleep Apnea
The more common of the two forms, obstructive sleep apnea is the result of blocked airflow during sleep, usually when the soft tissue at the back of the throat collapses and closes the airway. When the airway is blocked, the brain briefly wakes you up to resume breathing, often so quickly that you do not remember it happening. These interruptions can occur dozens or even hundreds of times per night, preventing you from reaching the deep, restorative stages of sleep.
