1. Your Nose is a Natural Pharmacy
Breathing through your nose doesn’t just filter air—it activates the production of nitric oxide (NO), a vital molecule that improves blood circulation, strengthens immunity, and enhances oxygen exchange in your lungs. Mouth breathing skips this entirely.
2. Nasal Breathing = More NO, Better Health
Studies show nasal breathing produces over twice as much nitric oxide as mouth breathing. And when researchers blocked nasal airflow? NO levels dropped dramatically—proving how essential the nose is in producing this “invisible helper.”
