Thermal treatment for sinusitis

What is thermal treatment for sinusitis?

Thermal treatment for sinusitis uses the properties of thermal waters to reduce inflammation in the paranasal sinuses, serving as an important complementary therapy, especially for chronic disease. Thermal treatment for sinusitis is effective, providing symptom relief and offering numerous advantages compared to other therapeutic alternatives. While conventional sinusitis treatment is based on medication, thermal treatment has been widely used as an effective complementary therapy that promotes good respiratory health.

Types of sinusitis

Sinusitis is defined as the inflammation of the mucosa of one or more paranasal sinuses. It can be caused by viral, bacterial, or fungal infections, allergic reactions, environmental irritants, or anatomical structural changes. Regarding the duration of symptoms, sinusitis can be classified as acute when symptoms last less than 4 weeks, subacute when symptoms last between 4 and 12 weeks, and chronic whenever symptoms last longer than 12 weeks.

What does thermal treatment for sinusitis consist of?

The mineral waters of Termas de Chaves are sodium bicarbonate and carbonated waters. Their therapeutic properties produce an anti-inflammatory, decongestant, and immunomodulatory effect, which can be applied to treat sinusitis through nasal irrigations, nebulizations, aerosols, sprays, and immersion baths. Their mechanisms of action can be divided into three categories:

• Mechanical: Nasal irrigation helps remove secretions, allergens, and irritants present in the respiratory tract.

• Chemical: Bicarbonate promotes the alkalization of inflamed tissues, contributing to reduced inflammation and, consequently, lower viral/bacterial proliferation. Carbonic acid, in turn, has a muscle-relaxing, analgesic, and antihistamine effect.

• Thermal: Warm water improves circulation, stimulating the drainage of the paranasal sinuses.

Different types of thermal treatment for sinusitis

At Termas de Chaves, you can find the following treatments for sinusitis:

• Complete inhalation with thermal water: This is one of the most frequent forms of thermal treatment for sinusitis, effectively decongesting the airways and reducing inflammation. It consists of 4 phases:

  • Nasal irrigation: Removes secretions, cleanses the nasal passages, and improves mucociliary function.

  • Aerosol therapy: Uses thermal water particles to reach the upper airways.

  • Nebulization: Allows fine particles to be inhaled deeply into the lungs, helping to thin mucus, relieve congestion, and promote bronchodilation.

  • Spraying: Uses a small jet of thermal water to eliminate any remaining secretions in the oropharynx.

• Thermal immersion baths (in a bathtub or pool): Promotes the relaxation of facial muscles (relieving headaches and facial pain) and respiratory muscles, facilitating the drainage of secretions.

What are the benefits of thermal treatment?

Evidence shows that thermal treatment provides the following benefits:

• Reduces inflammation;

• Improves drainage of the paranasal sinuses;

• Improves hydration of the nasal mucosa;

• Reduces the need for medication;

• Stimulates the immune system.

Scientific evidence on the effectiveness of thermal treatment

According to the literature, using thermal waters in patients with chronic sinusitis reduces the frequency and intensity of flare-ups, subsequently decreasing the use of antibiotics. Additionally, patients benefit from better respiratory function and recovery of the nasal mucosa. Thermal treatment for sinusitis is an effective complementary option, relieving symptoms and thus improving patients' quality of life. Regular use reduces the need for medication—always, of course, after medical evaluation and validation—promoting respiratory health in a natural way. Thermal treatment is more effective when performed regularly and over a longer period (an average of 12 to 15 consecutive days). The effectiveness of the treatment at Termas de Chaves may vary from patient to patient and depends on the type and severity of the sinusitis.

Advantages compared to other treatments

We can identify the following advantages when comparing thermal treatment with other therapies, namely the use of medication:

• Reduction of side effects: Medications can cause side effects, whereas thermal treatment is well-tolerated by most people.

• Long-term benefits: Some studies indicate that regular balneotherapy can provide a better quality of life in the long term, reducing the frequency and intensity of symptoms and flare-ups.

• Local action: Thermal treatment acts directly on the respiratory tract, which can be more effective in some cases than certain oral medications that have a systemic action.

Practical recommendations

We suggest some practical recommendations before starting your thermal treatment:

• Always consult your attending physician or a hydrologist physician before starting any thermal treatment. Termas de Chaves has a trained, experienced medical team ready to provide clarification and prescribe thermal treatments.

• Thermal treatment should not be seen as a substitute for medical supervision.

• Ensure that you receive treatment at spas with thermal waters from recognized sources.

• It is important to combine thermal treatment with a healthy lifestyle, such as practicing physical activity, maintaining a rich and balanced diet, and staying well-hydated.
