So what truly cause snoring. This may be quite a hard-to-answer question when were talking of only one cause. For in fact, there are many basic contributors that all funnel into the greater source of the problem.
Medically, snoring is defined as a noise caused by vibration from the airways of the respiratory tract that only appears during sleep.
The big question here is that, why, of all state, do we only experience snoring during restful moments?
Well, while we breathe 24/7, the likelihood that one snores during waking hours is very slim. This is due to the factor that only relaxed muscles can result to snoring.
During sleep, all our voluntary muscles are relaxed. The throat, in the same way as the triceps are relaxed is also resting while we sleep. The fact that tissues in the throat are soft, adds to the eventual output of vibrating sounds.
Once this tissue eases out, the passage of air will turn into a narrower passage. As you can see, narrowed passages causes louder noise because there is more room for friction, thus the vibration.
These same factors are also pointed as the reasons why there are differences in the loudness, pitch...
