Our nasal passages perform remarkable work such as humidifying, filtering, and regulating each breath we take. Yet, in today’s urban environments, this system is under increasing strain.
Prolonged exposure to dry indoor air, airborne pollutants, and allergens can disrupt the delicate balance of the nasal mucosa. The result? Chronic congestion, sinus inflammation, and reduced airflow — symptoms that are often overlooked but can significantly impact sleep, cognition, and overall wellbeing.
From a clinical perspective, nasal and sinus health are essential to the body’s first line of defence. When the nasal cavity is functioning well, it filters out up to 80% of airborne particles before they reach the lungs. However, when compromised, even mild inflammation can affect oxygen exchange and lead to mouth breathing, fatigue, or recurring sinusitis.
Evidence-informed steps to support nasal health:
Hydration and humidity: Maintaining adequate hydration and using humidifiers in air-conditioned environments helps preserve mucosal integrity.
Regular cleansing: Isotonic saline irrigation reduces particulate buildup and supports mucociliary clearance.
Functional breathing: Promoting nasal breathing supports nitric oxide production, which enhances vascular regulation and antimicrobial defence.
As awareness grows around the connection between respiratory function and overall wellness, nasal care deserves a place in our broader health conversation.
