Since the dawn of humanity, people have sought out thermal waters for their exceptional curative properties. These mineral waters spring up from the depths of the earth after a long underground journey that enriches them naturally.
As they rise towards the surface, these waters absorb the chemical properties and trace elements of the rocks they pass through. Their mineralisation depends on two crucial factors: the temperature of the water-rock exchanges and the duration of contact between these elements. This natural process guarantees a water free of pollution and bacteria, endowed with genuine curative properties.
Thermalism: a thousand-year-old tradition
The therapeutic use of thermo-mineral waters is what constitutes thermalism. The Romans were already exploiting these resources back in Antiquity to treat various ailments. Today, this approach remains a valuable complementary alternative to conventional therapies.
Classifying therapeutic waters
Specialists classify mineral waters according to two main criteria: their temperature at emergence and the presence of elements that are notable for their nature or their concentration.
Classification by temperature:
- Cold waters: below 20°C
- Hypothermal waters: between 20 and 35°C
- Thermal waters: between 35 and 50°C
- Hyperthermal waters: above 50°C
The main therapeutic categories:
Sulphurous waters: rich in sulphur and hydrogen sulphide, they effectively treat chronic infections of the mucous membranes and respiratory conditions such as rhinitis, otitis, asthma and bronchitis.
Sulphated waters: highly concentrated in sulphur, they are suited to kidney conditions. Enriched with calcium and magnesium, they also soothe eczema and the after-effects of burns.
- Chlorinated waters: concentrated in sodium chloride, they stimulate growth and treat developmental disorders.
- Bicarbonate waters: containing bicarbonate, they ease digestive troubles when sodium-based, or exert an anti-inflammatory effect on skin conditions when calcium-based.
- Oligo-metallic waters: depending on their composition, they treat a range of conditions. Rich in copper for dermatology, in iron against anaemia, or in arsenic for allergies.
| Type of water | Key composition | Main virtues |
|---|---|---|
| Sulphurous waters | Sulphur, hydrogen sulphide | Chronic infections of the mucous membranes, respiratory conditions (rhinitis, otitis, asthma, bronchitis) |
| Sulphated waters | Concentrated sulphur, calcium, magnesium | Kidney conditions, eczema, the after-effects of burns |
| Chlorinated waters | Sodium chloride | Growth stimulation, developmental disorders |
| Bicarbonate waters | Bicarbonate (sodium- or calcium-based) | Digestive troubles (sodium-based), skin anti-inflammatory (calcium-based) |
| Oligo-metallic waters | Copper, iron or arsenic depending on the source | Dermatology (copper), anaemia (iron), allergies (arsenic) |
When to choose a thermal cure?
The therapeutic indications keep broadening, particularly for chronic conditions that call for an alternative to purely drug-based treatment. Beyond the classic indications such as rheumatism and joint conditions, thermal cures excel in treating skin conditions that resist conventional therapies, notably eczema and psoriasis.
That said, no specific condition is required to benefit from a thermal cure. After a period of great fatigue or a stressful episode in your personal or professional life, a thermal cure makes for the ideal remedy. These stays allow your body to rest, recharge and strengthen your joints.
The recognised therapeutic virtues
Naturally pure and rich in mineral salts, gases and trace elements, thermal waters offer many therapeutic benefits:
Relief from rheumatism
Rheumatology accounts for 66% of the reasons for a thermal cure. Warm waters effectively ease pain thanks to mobilisation-pool baths and mud applications, which reduce muscle contractures while providing a sedative effect.
Regeneration of the respiratory tract
These waters excel in treating winter respiratory conditions such as bronchitis and otitis. They regenerate the respiratory mucous membranes, thin the mucus and clear the airways without recourse to antibiotics.
A natural alternative for chronic pain
For the persistent pain that accompanies some people for years without a satisfactory drug-based answer, thermal waters offer a natural solution. Back pain, headaches, osteoarthritic or muscular pain all see a significant reduction.
Dermatological effectiveness
Thermal water becomes an ally of atopic skin thanks to its purifying and antioxidant effects. Its anti-inflammatory and softening properties soothe eczema, rosacea and psoriasis by softening the skin and easing redness.
Tunisia’s thermal heritage
In Tunisia, the history of thermalism stretches back more than two millennia. This tradition reached its peak in Roman times, a period when the use of warm waters amounted to a veritable cult — an art of healing and of living.
An exceptional potential
Tunisia possesses a remarkable thermal heritage, with more than 100 thermo-mineral occurrences from north to south. Fifty recorded hot springs display the chemical composition needed for a diverse therapeutic use.
Most of these springs have been used in the traditional way since Roman times. The number of visitors to thermal hammams (traditional bathhouses) rises steadily from year to year.
Four modern thermal spas
The country has four thermal spas equipped with the most advanced technologies, offering specialised treatments according to the specific properties of their waters:
- The Hammam Bourguiba thermal spa (Jendouba Governorate)
- The Korbous thermal spa (Nabeul Governorate)
- The Djebel Oust thermal spa (Zaghouan Governorate)
- Djerba les Bains (Medenine Governorate)
These establishments offer cures that are at once curative — complementing medical or surgical care — and preventive against relapses and worsening. Each spa is set on remarkable geological sites that allow the natural emergence of thermal waters.
A resource worth cherishing
Thermal waters are naturally pure underground resources, with a stable physico-chemical composition and scientifically recognised therapeutic qualities. Modern thermalism applies the latest technologies to treat chronic or degenerative diseases naturally.
Immersion in these naturally warm waters, laden with beneficial elements, relaxes and softens the skin and the body’s tissues. It is well worth cherishing this national treasure and enjoying the immense benefits of these precious thermal waters, for body and mind alike.
