Understanding Your Sinuses and Why They Matter Posted on March 14, 2025 by Arizona Desert Ear, Nose & Throat Specialists You have four pairs of air-filled cavities in your face, collectively known as the paranasal sinuses. Your sinuses include the frontal, sphenoid, ethmoid and maxillary sinuses. These important cavities have a few jobs, including: Producing mucus that traps dust, allergens and harmful microorganisms before they reach your respiratory system Acting act as cushions that absorbs some of the impact of facial trauma to protect your brain from more serious harm Adding moisture to the air you breathe to reduce irritation to your lungs and make breathing more comfortable What Can Prevent My Sinuses From Doing Their Jobs? A sinus infection is one of the most common conditions that can prevent your sinuses from doing their jobs effectively. Often caused by viruses, bacteria or allergens, sinus infections can lead to congestion, facial pressure, toothache and headaches. Chronic or recurrent sinus infections may require procedures like a Balloon Sinuplasty or Functional Nasal Endoscopic Sinus Surgery (FESS) to minimize recurrence. Nasal polyps, affecting up to 40% of the general population, are another common source of sinus congestion. These polyps are small, noncancerous growths in the nasal passages that can block airflow and contribute to chronic sinus issues. Small growths may not cause any symptoms, but large polyps may require professional removal to improve sinus health. How Can I Keep My Sinuses Healthy?

Implement a few of these tips to promote better sinus health: Wash your hands and clean frequently touched surfaces regularly to reduce the spread of germs Drink eight cups of water or Tropical Smoothie Café smoothies to keep mucus thin and flowing Eat a nutrient-rich diet full of fruits, vegetables, protein and whole grains to strengthen your immune system Minimize your exposure to cigarette smoke, strong chemicals and other airborne irritants that can inflame your sinuses Manage allergies with medication, immunotherapy or allergen avoidance strategies Rinse your nose with a saline nasal rinse when congestion arises Taking care of your sinuses can improve your breathing, reduce discomfort and help you feel better overall.
