When a person falls asleep, the muscles that hold the larynx open will relax, causing the narrowing of the upper airway, and the vibration caused by the air passing through the narrow larynx is the snoring sound we hear. When the airway is narrowed to a certain degree or even closed, the breathing becomes blocked and the brain receives the instruction of breathing difficulty, it will order the body to breathe hard, causing a short awakening. Sleep may be interrupted hundreds of times a night. At this time, people around us can see the performance of snoring like thunder, stopping suddenly for more than 10 seconds, and then resuming with a sudden “boom”, sometimes for up to 2 minutes. People who snore a lot are in the condition of oxygen deprivation for a long time, which will cause different degrees of damage to heart, brain, lungs and other organs, and may cause sudden death if a sleep breathing stop is too long.
