Why do we snore is a very common question often comes to mind. So now lets find out the answer.
What is snoring?
Snoring, like all other sounds, is caused by vibrations that cause particles in the air to form sound waves. For example, when we speak, our vocal cords vibrate to form our voice. When our stomach growls (borborygmus), our stomach and intestines vibrate as air and food move through them.
While we are asleep, turbulent airflow can cause the tissues of the nose and throat to vibrate and give rise to snoring. Essentially, snoring is a sound resulting from turbulent airflow that causes tissues to vibrate during sleep.
Why do we Snore?
While we are breathing, air flows in and out in a steady stream from our nose or mouth to our lungs. There are relatively few sounds when we are sitting and breathing quietly. When we exercise, the air moves more quickly and produces some sounds as we breathe. This happens because air is moving in and out of the nose and mouth more quickly and this results in more turbulence to the airflow and some vibration of the tissues in the nose and mouth.
When we are asleep, the area at the back of the throat sometimes narrows. The same amount of air passing through this smaller opening can cause the tissues surrounding the opening to vibrate, which in turn can cause the sounds of snoring. Different people who snore have different reasons for the narrowing. The narrowing can be in the nose, mouth, or throat.
What are the factors that causes(provokes) snoring?
1. Sleeping on your back: In this sleeping position gravity pulls the jaw and tongue down and back. This as a result causes mouth to open and tongue to drop back into the airway which in turn causes narrowing of the passage.
2.Smoking: Smoking may causes inflammation and swelling of lining of throat which in effect causes throat to become more narrow.
3.Breathe through mouth rather than nose:Breathing through mouth causes inhaled air to directly hit the back of the throat.This increases turbulence and causes vibration.
4.Blockage of nose: Any blockage of the nose by cold, injury, allergy etc. can lead to snoring as all these factors causes narrowing of nasal passage.
5.Obesity: Obesity adds extra fat to the tongue and throat thus making it easier for airway to become blocked.
