Your respiratory system has an upper and lower tract that work together to help you breathe in oxygen and breathe out carbon dioxide. The connection between the upper and lower respiratory systems forms the foundation of the unified airway hypothesis. The hypothesis suggests that issues in the nose and throat can influence the lungs. This connection may help explain the relationship between asthma and nasal inflammation.
How Nasal Inflammation Impacts Asthma
Asthma is a chronic lung condition that causes the airways to become inflamed and narrow, preventing regular breathing. One study found that inflammation from sinusitis (inflammation of the sinuses) or rhinitis (inflammation of the nose) can spread to the lungs and worsen or even trigger asthma symptoms.
Chronic rhinosinusitis, a long-term nasal inflammation, is often linked to asthma. In this case, the inflammation is more complex and is likely due to:
- Impaired epithelial barrier. The epithelial cells that line the nose and sinuses may be less effective at protecting against irritants and pathogens.
- Dysregulated immune response. The immune system may overreact or respond inappropriately to viruses and bacteria, leading to chronic inflammation.
Although asthma has no cure stop, safeguarding your respiratory system against frequent nasal and sinus infections is one way you can help reduce lung inflammation.
How Can I Protect My Respiratory System?

- Exercise regularly. Physical activity can boost your immune system and strengthen your lungs and heart, helping to ward off respiratory infections and inflammation.
