Snoring and sleep apnea syndrome
Last updated on March 20, 2021.
Many of you who are taking CPAP therapy may have once been said to be "snoring terrible." On the other hand, I think that there are many people who have been told "I'm no longer snoring" after starting CPAP therapy.
Snoring is noise such as "gagaga" or "gogogo" that you can hear according to your breathing during sleep. Sound is the vibration of the air, but snoring is caused by the vibration of the upper airway (the path of breathing from the mouth, nose to the throat Buddha). In sleep apnea syndrome (SAS), the base of the tongue (lower base) loosens along with deep sleep and hangs down in the back of the throat and narrows. And if you block the upper airway, you will not be able to breathe and you will be "apnea". When the base of the tongue is on the verge of blocking the upper respiratory tract, the air of breathing barely flows, but vibration occurs because it flows through a very narrow place. This is the true identity of SAS patients.
Mechanism of snoring (from the Japan Society of Respiratory Medicine)
You can barely breathe when you are snoring, but apnea occurs during the silence between snoring and snoring. If the base of the tongue spreads with CPAP therapy, snoring and apnea disappears.
The subsidence of the base of the tongue is a major cause of snoring, but the causes of snoring include adenoid (tonal) enlargement in children, nasal congestion due to colds and rhinitis, nasal distraction, and extreme obesity. It looks like you are sleeping well when you snoring, but the snoring is unstable breathing and the sleep becomes shallower. The snoring itself is not considered a disease, but chronic snoring is never desirable.
Although it is not necessarily the same as "snoring" and "SAS", it is recommended that those who have severe snoring should consult a specialized medical institution such as the respiratory Internal medicine.
