How to do nasal lavage? Discover the benefits of the practice

THE nasal wash It is a common practice to clean the respiratory tract in cases of allergies and sinusitis or simply to maintain nasal hygiene.

The practice helps remove mucus, allergens, pollutants and other impurities from the nostrils, contributing to easier breathing and relieving symptoms of allergies and sinusitis. It is also a preventative measure against respiratory infections as it helps keep the airways clear.

“Daily nasal washing is recommended, especially in urban centers where there is a high level of pollution. It should also be performed on people who have respiratory diseases such as allergic rhinitis and recurrent airway infections,” explains Bruno Borges de Carvalho Barros, otolaryngologist.

There are several devices available on the market for performing nasal lavage, each with its own advantages and indications. Furthermore, the practice of cleaning the airways has no contraindications and can be performed on people of all ages.

“It can be performed from newborns onwards, but it must be appropriate for each stage of life. In newborns, it should be performed using a small volume and low pressure, using a pressurized saline solution or even a dropper. In children up to three years of age, it is recommended that it be performed using syringes. From three years of age onwards, high volume and low pressure lavage can be performed using small bottles,” adds Barros.

The amount of saline solution used in nasal lavage varies depending on individual needs and the type of device used. It is important to follow the manufacturer’s instructions and consult a doctor to determine the ideal volume.

Although nasal lavage is safe, some precautions are important, as explained by otolaryngologist Fabrizio Ricci Romano.

“When using the syringe, you have to be careful not to contaminate the object or hurt the child’s nose with the tip of the syringe. And never use too much pressure to wash the nose,” he says.

See below how to perform the procedure safely.

1. Preparation: use a sterile saline solution, which can be purchased ready-made or made at home
2. Positioning: tilt your head forward and slightly to the side over a sink
3. Application: insert the nozzle of the syringe, bottle or spray into the nostril and apply the solution, letting the solution run out of the other nostril
4. Repetition: Repeat the process on the other nostril.
5. Finalization: Blow your nose gently to remove excess solution and mucus.

It is important not to overdo the frequency of washing. Excessive use can lead to the removal of protective mucus, nasal dryness or even irritation.

The general recommendation is to wash your teeth once a day in cases of severe allergies or sinusitis, and less frequently for maintenance. For specific cases, it is always best to consult a doctor for guidance.
