Your sinuses are air-filled pockets found in your cheeks, behind your forehead and eyebrows, on either side of the bridge of your nose, and behind your nose. They can get clogged easily. Healthy sinuses are lined with a thin layer of mucus that traps dust, germs, and other air particles. Ideally, tiny hair-like cilia sweep mucus and anything trapped in it out of the sinuses, down the back of your throat, and into the stomach.
