On the other hand, the vast majority of folks with rhinitis and sinusitis don't develop OSA.
I’m not sure we can say that most with sinus issues don’t have OSA. In “Obstructive Sleep Apnea is a Common Disorder in the Population—A Review on the Epidemiology of Sleep Apnea” they found that 37% in men and 50% in women with sleep apnea caused by an obstruction in the upper airway. That’s a lot of people.
On the other hand, in “Epidemiology and Burden of Nasal Congestion” they write “…it is generally accepted that approximately 10% to 20% of the global population suffers from allergic rhinitis…” That’s fewer people with rhinitis than OSA. Having said this, I totally agree with you that it is impossible to make any scientifically valid connections.
Also, regarding mouth breathing as a result of running short of oxygen (O2), I just wanted to try to make a clarification for those not familiar with the Buteyko method. What was discovered is that mouth breathers tend to over-breath. The result is that they blow off too much carbon dioxide (CO2). Without enough CO2, the body can’t make use of all the extra oxygen it has – not to method other adverse effects.
So the problem with mouth breathing, and the reason that people that are pulling in a lot of air through their mouths during asthma or panic attacks aren’t doing themselves a favor, is actually because they’re blowing off too much CO2. Interestingly, what was discovered is that by teaching folks in the middle of an asthma attack to slowly breathe through nose that the attack could be stopped. The problem was actually a lack of CO2.
Granted, during an OSA event we know that blood oxygen levels drop precisely because the airway is being choked off. Rightly so, your body naturally responds to this drop by having you unconsciously open your mouth during sleep. This makes total sense.
However, I just want to try to make the distinction between unconsciously opening your mouth during an OSA event and mouth breathing during the day due to a perceived “lack of oxygen”. Mouth breathing during OSA makes perfect sense but generally, it is not a good idea to mouth breath while awake for many reasons including blowing off too much CO2.
I’m a mouth breather and have really tried to understand what leads to this behavior and what can be done about it. I started by reading about how diet and the importance in being breast fed is key to proper facial and airway development – see “Cranial & Dental Impacts on Total Health” from the Weston Price Foundation. I then went on to learn about the Buteyko breathing method, myofunctional exercises to tone airway muscles and even restructure the face. Of course, adding air filtration to deal with allergens, eliminating problematic foods, and the like to eliminate allergic reactions is also important.
