The natural reaction of the sinuses to polluted air is the secretion of mucus which is designed to bind with the dusts that make their way into the respiratory tract during inhalation. Spending any length of time in a dust-filled environment can lead to a situation where the body is unable to secrete the requisitely large quantities of mucus. What then happens is that the mucus thickens, giving rise to inflammatory conditions.
The treatment removes all the debris and bacteria from inside the nose and sinuses. A warm isotonic solution at a concentration of 0.9 per cent has no difficulty in softening and dislodging internal deposits and, thanks to the force of gravity and the Venturi effect, a hypotension is generated, making it possible to cleanse every recess thoroughly.
Under domestic conditions, we can make use of a straightforward device designed for the purpose. It is nothing other than an irrigator with a nozzle at the end. Designed to fit the nostril, the nozzle is bean-shaped. This simple piece of equipment is available in almost every chemist’s. Cleansing of the sinuses is carried out with a NaCl solution at a physiological concentration of 0.9 per cent. In order to obtain the right concentration, dissolve two flat teaspoons of table or pharmaceutical salt in one litre of water at body temperature. The treatment is performed by letting the mixture flush through the nose and sinuses.
