In TCM, sleep Apnea syndrome is a chronic condition characterized by periods of shallow breathing or pauses in breath during sleep. Sleep Apnea is categorized as either obstructive or central. Obstructive sleep apnea occurs when the airway collapses or is blocked during sleep. Central sleep apnea is a neurological condition in which the brain doesn't send the proper signals to the breathing muscles. People with Restless Legs Syndrome experience unpleasant creeping or tingling sensations and discomfort in the legs while lying down.Complications of Sleep Apnea Syndrome1. High blood pressure2.
