Inflammation of the sinuses, the cavities around the nose and eyes, is called sinusitis. It is one of the most common problems among people who suffer from respiratory allergies, and occurs when environmental irritants cause excess mucus to build up and block the drainage holes.
The result? Headaches, congestion, facial pressure, runny nose, coughing, or even general fatigue. Fortunately, there is a very effective natural remedy to relieve all the symptoms of sinusitis: thermal steam.
In this article, we explain how steam works in the respiratory therapies offered at our balneario in Navarra. Discover why coming to Fitero could be the solution to your sinusitis!
Steam as a natural nebuliser: clearing the airways
The main reason why thermal steam can relieve sinusitis is because it acts as a natural nebuliser.
When we breathe in or inhale mineral-rich vapour, our mucus begins to soften. Secretions become more fluid, passages that had been blocked by dust, pollen or pollution begin to drain, and the feeling of pressure and nasal congestion gradually diminishes.
This is something you can experience, for example, in the thermal sauna at Balneario de Fitero, a natural stone grotto with 100% relative humidity created by the steam from the spring itself.

Stepping into our sauna is a very relaxing experience, and the results are real. It allows you to:
- Breathe more easily, without so much mucus.
- Reduce pressure in the sinus area.
- Deep clean your nose and bronchial tubes.
- Get quality rest.
Goodbye to symptoms: relief from allergic rhinitis and asthma
If you suffer from allergic rhinitis, sinusitis or asthma, do not despair. Just as coming to our balneario improves the symptoms of bronchitis, the same is true for these other respiratory conditions.
Thanks to the combination of different hydrothermal treatments, such as the aforementioned sauna, micronised thermal water aerosols (highly effective inhalations for allergies) and halotherapy sessions, you can significantly alleviate symptoms such as:
- Congestion and rhinorrhoea, thanks to improved mucosal hygiene.
- Coughing and facial pressure, as they facilitate the drainage of secretions and reduce sinus inflammation.
- The feeling of shortness of breath if you have asthma, because the improvement in lung ventilation and oxygenation is remarkable.

And if you add a bath in our hyperthermal mineral-medicinal waters to the spa’s respiratory therapies, the benefits are multiplied even further. Thanks to their high mineral content, they have anti-inflammatory, mucolytic and antihistamine effects. The properties of Fitero’s water are incredible!
Inhalation techniques: how to get the most out of each vapour session
If you want to make the most of your visit to Balneario de Fitero and enjoy the benefits of thermal steam for treating sinusitis, here are our tips:
- Come relaxed, with time and a desire to immerse yourself in our waters.
- Once here, breathe deeply and slowly: let the thermal steam reach your nose, your mouth and then your bronchial tubes. There’s no rush!
- Keep your body hydrated: drink water before and after enjoying the benefits of steam. This helps to loosen mucus so that you can eliminate it more easily.
- Complement your thermal experience with treatments such as aerosols or halotherapy to maximise the mucolytic effect.
- Repeat the sessions or extend your stay. The longer you stay, the longer the benefits will last.
If you really suffer from the symptoms of allergies and sinusitis, we recommend choosing our Respiratory Programme, specially designed for people with respiratory or allergic problems. You can stay for between 2 and 5 nights and see for yourself the power of thermal steam to relieve sinus inflammation.
