Sleep Apnea is a common sleep disorder cause by the soft tissue in the throat falling and blocking the airway. When this happens, our bodies naturally wake us up briefly to open the airway so we can breathe again. Sleep Apnea can cause complications down the road if not treated early. Treatment options range from machines that help with breathing to surgery.
