The Benefits of Seawater
The sea is much more than just a soothing landscape: it is a natural resource with countless benefits. For centuries, its benefits for health, well-being, and the revitalization of the body have been recognized. Today, scientific research confirms what maritime tradition had already intuited: seawater is a valuable ally for our physical and mental well-being.
Aware of this natural treasure, we wanted to offer you direct access to its benefits through a seaside thalassotherapy experience. It was with this in mind thLes CorallinesThalasso & Resort was founded.
Seawater: A Natural Remedy for Skin Problems
Seawater is a natural remedy for skin problems, thanks in part to its high mineral and trace element content. It helps deeply hydrate the skin while gently purifying it.
Its benefits for the skin include:
• Natural, long-lasting hydration, without the need for commercial creams;
• Accelerated healing of wounds or irritations;
• A regulating effect on the skin’s pH;
• A visible reduction in acne and blemishes;
• Protection against inflammation and redness;
• Faster cell regeneration thanks to iodine, zinc, and magnesium.
Seawater is therefore ideal for sensitive, reactive skin or skin prone to dermatological issues.
Saltwater: A Powerful Stress Reliever
Did you know that seawater helps combat stress and chronic fatigue? In fact, it naturally contains iodine, which plays a crucial role in the functioning of the thyroid gland—the regulator of mood and energy. Proper thyroid function helps prevent disorders related to anxiety, irritability, and stress. The effective distribution of hormones facilitated by the iodine in seawater thus contributes to the body’s well-being by providing a general sense of calm.
In addition, seawater is rich in essential trace minerals such as magnesium, known for:
• Reducing nervous tension;
• Improving sleep quality;
• Promoting optimal muscle recovery after exercise;
• Providing a sense of overall relaxation for the body and mind.
Heated seawater baths, hydrojet massages, underwater showers, and all other thalassotherapy treatments are therefore recommended to relieve tension and restore lasting well-being.
At the ThalassoLes Corallines, we offer a wide range of thalassotherapy treatments as well as comprehensive “spa programs” packages for a deeply rejuvenating and restorative experience.
Seawater to address your deficiencies in trace elements and minerals
Seawater contains all the minerals and trace elements necessary for the body to function properly, in proportions that are easily absorbed by the body. It is particularly recommended for fatigue, chronic stress, or nutritional deficiencies.
Among the main elements found in seawater:
• Magnesium, a natural stress reliever;
• Calcium, essential for bones and muscles;
• Potassium, which regulates cellular hydration;
• Zinc, which supports immunity and wound healing;
• Iodine, essential for proper hormonal function.
By gently strengthening your body, seawater acts as a true natural shield against external threats, particularly viruses and bacteria. It supports your immune system and actively contributes to your vitality.
Parcours Marin: A Sensory Immersion in Heated Seawater

At the heart of our “Première Ligne” area, the “Parcours Marin” is an invitation to absolute relaxation. Heated and bathed in natural light, this approximately 200 m² seawater pool offers a true sensory journey through various hydrotherapy zones.
Here you’ll discover:
• Massage jets to relax muscles and relieve tension;
• A “swan-neck jet” to relieve tension in the shoulders and neck;
• A Jacuzzi to promote circulation and relaxation;
• A counter-current swimming;
• A leg circulation circuit to stimulate venous and lymphatic circulation.
This thalassotherapy ritual is the perfect complement to a treatment or spa program, working on both the body and the mind. It’s available with a 2-hour pass, weekdays or weekends, by reservation, for a wellness break at your own pace.
As you can see, seawater is a tremendous asset for health and well-being. So don’t wait another second—take the plunge and experience its benefits for yourself!
