Nasal mucus may be abundant, dry or thick in case of upper respiratory system inflammations (irritations, allergies, infections). Nasal obstruction (polyps, benign tumors, etc.) and repeated nose blowing can damage the mucosa and promote irritation, infections and sinus pains. The regular or occasional use of Humer Bottle pack moisturizes the nasal fossae without irritating them. This eases the mucus removal and prevents the mucosal irritation and dryness.
