How Allergies Affect the Airways

  1. Immune Overreaction: Allergies occur when the immune system mistakes harmless particles like pollen for dangerous invaders.
  2. Inflammatory Response: The body releases histamines that swell and inflame the nasal passages and airways.
  3. Mucus Surge: Extra mucus production traps allergens but also clogs breathing pathways.
  4. Sneezing Reflex: Rapid sneezes expel allergens from the nose, acting as a built-in defense mechanism.
  5. Nasal Congestion: Swollen tissues and mucus buildup make it harder for air to flow freely.
  6. Cough Trigger: Irritation in the throat and bronchi stimulates coughing to clear the airways.
  7. Asthma Link: In sensitive individuals, allergies can inflame the lower airways and provoke asthma attacks.
  8. Oxygen Disruption: Constricted airways reduce airflow, leading to shortness of breath and fatigue.
  9. Seasonal Patterns: Pollen, dust, or pet dander can trigger symptoms that vary with environment and time of year.
  10. Maintenance Required: Avoiding triggers, using antihistamines, and keeping indoor air clean help keep airways open and calm.
