Why Nasal Health is a Foundational Part of Human Physiology Not Just a Comfort Issue
We often overlook the nose until it's congested. But from a physiological standpoint, nasal breathing plays a critical role in supporting healthy function across multiple systems in the body.
The nasal cavity isn’t just an air passage it:
- Filters particles, allergens, and pathogens
- Humidifies and warms incoming air to protect the lungs
- Regulates nitric oxide production, which supports cardiovascular and immune function
- Encourages diaphragmatic breathing, improving oxygen efficiency and calming the nervous system
When nasal airflow is restricted (due to congestion, allergies, or chronic inflammation), we often default to mouth breathing which bypasses these key mechanisms and may lead to:
- Poor sleep quality and oxygenation
- Increased risk of upper respiratory infections
- Chronic dry mouth and bad breath
- Altered craniofacial development in children
- Exacerbation of conditions like ADHD (attention deficit hyperactivity disorder), sleep apnea, and fatigue
🧠 Research increasingly supports the link between nasal function and systemic health yet it remains underprioritised in everyday wellness.
Supporting nasal health daily through hydration, decongestants, nasal sprays, and breathing retraining isn’t just about comfort, it's about improving the way your body functions at its core.
