How Our Sinuses Work
Have you ever noticed how sometimes when you are congested your nasal passage feels clogged when lying down? You stand up and it seems to clear up a bit and you can breathe better. Do you ever wonder why that is?
These symptoms are a result of your sinuses, which are air-filled membranes within your skull in the facial area near the brow. They are connected to your nasal passages by a series of tubes or channels that are collectively known as the osteomeatal complex. Because of this complex, air can flow from your nose into the sinuses. This in turn makes it possible for mucus to drain from the sinuses into your nose.
