Methods of Mineral Water Inhalation and Their Effects on the Respiratory Tract

How Temperature and Droplet Size Affect the Respiratory Tract

The temperature of the inhaled aerosol is a key factor, influencing inflammation, mucosal hydration, and mucus clearance. An aerosol at around 37–38 °C hydrates the mucosa, loosens dried mucus, stimulates the ciliated epithelium, and facilitates expectoration.

The alkaline nature of Vincentka additionally neutralises the acidic environment of diseased mucosa and relieves discomfort. Iodine and chloride ions help dissolve mucus, calcium has an anti-inflammatory effect, and the presence of CO₂ supports blood circulation and metabolism.

Droplet size determines the depth of penetration:

• Fine mist (< 10 μm) penetrates the lower respiratory tract, reaching bronchi and alveoli.
• Coarse mist (10–40 μm) settles in the upper respiratory tract (nose, pharynx, larynx).
• For the paranasal sinuses, an aerosol with particles < 1 μm is ideal, as these can return into the cavities during exhalation.
