Snoring is caused by a blockage in the back of the throat. What you hear is the tongue forced to the back of the throat when a person is lying on their back.

When people snore they don't always stop breathing, but there are chemicals in the brain that should trigger breathing that are not stimulated when a person snores. Without the stimulation the person will often stop breathing.

When a person obstructs at night and stops breathing, oxygen levels drop dramatically and hormones and adrenaline surge. Those hormones contribute to high blood pressure, irregularities of the heart and can trigger heart attacks
