Asthma and the “United Airway” Connection
Why managing your nose is the secret to mastering your asthma in the Southern Highlands
If you live in the Southern Highlands, you know that our beautiful scenery comes with a side of seasonal challenges. Whether it is the crisp, frosty morning air or the heavy pollen from our lush local gardens, your respiratory system often bears the brunt of the changing seasons.
At Moss Vale Community Pharmacy, we frequently see patients who are incredibly diligent with their asthma preventer inhalers, yet still feel breathless, “tight,” or prone to coughing fits. The missing piece of the puzzle is often right under their nose—literally. According to Asthma Australia, roughly 80% of people with asthma also experience allergic rhinitis (hay fever). When you treat the two conditions as a single, connected system, you can dramatically improve your ability to breathe freely.
The “United Airway” Concept
Medical professionals now view the respiratory tract not as separate upper and lower parts, but as one continuous, interconnected system. This is known in clinical terms as the “United Airway.” If the delicate lining of your nose becomes inflamed due to hay fever, it sends chemical “danger signals” system-wide, which can trigger inflammation right down into your lungs.
When your nose is blocked, you lose your body’s natural air-conditioner. Your nose is expertly designed to:
- Filter: Trap microscopic dust, pollen, and allergens before they enter the body.
- Warm: Heat cold winter air to body temperature.
- Humidify: Add moisture so the air doesn’t irritate the sensitive lining of the lungs.
When nasal congestion forces you to breathe through your mouth, cold, dry, and allergen-filled air bypasses these defenses and hits your lungs directly. This is a primary trigger for an asthma flare-up.
How the United Airway Functions
Is Your Nose the Hidden Culprit?
Many people tolerate mild hay fever without realising it is sabotaging their asthma control. Check if you are experiencing any of these triggers:
The Obvious Signs
- Constant sneezing, or a runny, dripping nose.
- Itchy, watery, or visibly red and irritated eyes.
- A persistent “blocked” feeling that forces you to breathe through your mouth.
The Hidden Signs
- Night-time Issues: Snoring, poor sleep quality, or waking up with a severely dry mouth.
- The Constant Cold: Feeling like you always have a “head cold” that never quite clears up.
- Physical Pressure: Dull headaches or deep pain across your cheeks and forehead (sinusitis).
- Voice Changes: A husky or hoarse voice and a frequent need to clear your throat due to post-nasal drip.
Have you noticed the “Allergic Salute”?
If you or your child frequently wipe or rub the nose in an upward motion, it is a classic sign of chronic nasal itching and congestion. Over time, this repetitive gesture can even cause a faint, horizontal crease to appear across the bridge of the nose.
Practical Steps to Breathe Easier
Managing the “Top End” (your nose) can significantly improve the “Bottom End” (your lungs). Here is how you can take proactive control of your United Airway:
- Saline Rinses: Using a daily salt-water nasal wash helps physically flush pollen, dust, and irritants from the nasal passage before they can trigger a systemic allergic reaction.
- Intranasal Corticosteroids: Daily preventative nasal sprays are often the “gold standard” for hay fever. However, they take several days to reach peak effectiveness and must be sprayed using the correct technique to avoid nosebleeds and ensure the mist reaches the sinus cavities.
- Timing is Everything: Do not wait for symptoms to become unbearable. Start your hay fever prevention medications several weeks before the spring pollen season peaks.
- Review Your Asthma Action Plan: Every person with asthma should have a written Asthma Action Plan from their GP. Ensure your plan specifically addresses how and when to manage hay fever flare-ups.

Are You Over-Relying on Your Reliever?
If you need to use your blue reliever puffer (like Ventolin or Asmol) more than two days a week, your asthma is not well controlled. This is a crucial sign that you need to speak with your GP about adjusting your daily preventer medication.
Asthma Emergencies & Thunderstorm Asthma
During spring and early summer, the Southern Highlands can be susceptible to “Thunderstorm Asthma” events, where extreme weather causes pollen to burst into tiny particles that bypass the nose and enter the lungs deeply. If you or a loved one experience severe breathlessness, cannot speak a full sentence, or find reliever puffers are not working, follow your Asthma Action Plan and call 000 for an ambulance immediately.
