Thalassotherapy, also known as seawater therapy, isn’t just another wellness fad. This centuries-old practice has transformed into a modern luxury experience, drawing spa enthusiasts and medical tourists to coastal retreats worldwide.
Jump to:
Thalassotherapy harnesses the raw power of the ocean—its mineral-rich waters, nutrient-dense seaweed and therapeutic mud—to restore and rejuvenate. The Greeks know it (“thalassa” means sea in ancient Greek), and science backs it up. Our bodies crave the ocean’s natural elements, from magnesium to potassium to iodine.
The Magic Behind Thalassotherapy

Step into a thalassotherapy spa and let the ocean work its magic. Your journey might start in heated seawater pools, where gentle waves and targeted jets melt muscle tension.
Next comes the signature treatment: nutrient-rich seaweed wraps that transform your skin while drawing out toxins. Meanwhile, invigorating salt scrubs polish away the old while the misty sea air works subtle alchemy on the mind and lungs.
The brilliance of these treatments lies in their simplicity. Your skin naturally absorbs the ocean’s healing minerals, kickstarting circulation and easing everything from deep-set arthritis to persistent anxiety.

Biarritz has been synonymous with ocean-inspired wellness since the 19th century when European nobility flocked there for seaside healing.
