It is a non-medicinal treatment using the microclimate of natural karst caves, benefiting the lungs. Inhalation of air in these caves, with low temperatures of 13.8–14.0°C, low humidity of 15.4–16.0%, and increased CO2 content, activates thermoregulation and accelerates metabolism. Increased air radioactivity, influenced by radon, stimulates adaptive mechanisms, hormone production, and enhances endocrine organs, reducing immunoglobulins and antibodies, increasing T lymphocytes, and enhancing phagocytosis. Elevated negative ions positively affect the nervous and cardiovascular systems. The silence and unique conditions of cave therapy create psycho-emotional comfort.
