You may have brushed off your loud snoring, thinking it’s normal and happens to everyone, but did you know it may be a sign of a health problem? Sleep apnea is a disorder in which breathing stops repeatedly during your sleep. It can become serious to the point of causing other health complications. Loud snoring and constant waking during the night are just two of the symptoms of sleep apnea. The causes and risk factors range from genetics and health conditions to lifestyle habits.
