Are you constantly snoring and disturbing your spouse while you sleep? There is a possibility you have sleep apnea, a common sleep disorder that causes you to stop breathing when you sleep. This occurs when your airways are blocked, which limits the amount of air that reaches your lungs.
When breathing is constricted, you may wake up temporarily when your brain and body are deprived of oxygen. Most cases of sleep apnea are caused by the back of the throat collapsing. Muscles relax while you sleep, so if you sleep on your back, gravity can cause the tongue to fall back, narrowing your airway and reducing the amount of air that reaches your lungs.
