What is Thalassotherapy? June 30, 2016

“The sea cures all ailments of man.” – Plato

Since ancient times humankind has always turned to water for healing purposes. Water was considered sacred and nobody questioned its balancing and well-being effects. Today we use the term “Thalassotherapy” and treatments are available almost everywhere. But what is Thalassotherapy exactly?

Thalassotherapy, as a curative method, originated from the Greek (“Thalassa” means sea, “therapeia” means healing) and it is defined today as a seawater cure in a medically supervised environment. It is not only limited to the water itself. Treatments that apply seawater, seaweed, mud, sand and basically all substances coming from the sea are used for curative and preventative purposes, too.

Thalassotherapy centres appeared and became popular in the last century, first in France, as an alternative healing way. Official Thalasso centres must be located at no more than 500 metres distance to the sea, have a coastal climate and can use only pure, clean seawater. In France there is a severe regulation, which states that no factory or industrial complex must be found in a 10 km radius from the Thalasso centre in order to guarantee the pureness of the water.

Most famous centres in the world are located in France, Great Britain, around the North-African cost, in Greece and at the Dead Sea. In this context it is interesting to note that from a Thalasso aspect the coast in France is divided as follows: The one close to the English Channel is invigorating, the cost of the Atlantic Ocean is tonic, while the Mediterranean part has relaxing qualities. According to French experts, thalassotherapy is one of the best remedies to mineralise and detoxify our body.

According to recent research, an 8-day stay at a thalassotherapy centre restores the balance of the body for the next 6 months. It means that a cure twice a year can contribute significantly to our health and well-being.
