Its name comes from the word “Talassa” which means “sea.”

It involves the therapeutic use of seawater and the various marine climatic and environmental factors. Water is taken away from the seashore, purified and sterilized to ensure its purity and cleanliness.

Thalassotherapy properties are based on some elements of the sea and its antitumor, antibacterial and antiviral characteristics.

The absorption of marine elements, such as iodine and sodium, make the skin renew and heal faster and better.

In addition, seaweed has antibiotic, antitumor, antioxidant, antiviral and delays skin aging effects. They are rich in vitamins A, B, C, E, F, and K, iron, calcium, proteins and minerals.

Sea air is rich in ozone and iodine, has relaxing and antibiotic properties, which increases the body’s defenses.

If the therapy is applied inside the sea, we will also obtain the effect of massage by the waves and the movement of the water.
