It looks like it hey. Hear is an example: If you catch a cold often, or suffer from sinusitis worse than Kaa's from Jungle Book, it's possible that you are not breathing right. Breathing is really essential, if you do not breath properly then your sinuses begin to panic which is why most people with Asthma are most likely to get Asthmatic bronchitis at some point in their lives.
If the airways are inflamed, air has more difficulty getting to your lungs. With less air getting in, you can feel short of breath. You may wheeze and cough in an attempt to draw in more oxygen through tightened passageways. So if you did not have shortness of breath you sinuses would not have the urge to make more mucus as it reacts.
It is like when your gums are swollen, you might feel pressure on the sinuses but once you fix the sinus problem then your sinuses snap back to really and work normally.
I hope you understand what I mean...
