This video shows what happens inside your body if you snore or have sleep apnea.
Sleep apnea causes frequent interruptions in breathing as you sleep. It disrupts your rest, which can pose serious health risks. Loud snoring is often a symptom of sleep apnea. You snore when your tongue falls back against the back of your throat and it vibrates as you breathe in and out. In apnea, your throat muscles relax so much that they block your airway. When this happens, you can stop breathing for ten seconds or more. Carbon dioxide builds up and causes your brain to signal you to wake up. You do, briefly, and begin to breathe normally again. These brief interruptions can happen many times an hour and can severely hurt your health.
