What type of therapy involves the use of sea products and marine elements?

Thalassotherapy is a specialized form of therapy that utilizes seawater, sea products, and other marine elements for therapeutic purposes. This therapy focuses on the healing properties associated with the ocean, including mineral absorption through the skin and the benefits of various seaweeds and algae, which are rich in vitamins and nutrients. Intended primarily for relaxation, rejuvenation, and skin health, thalassotherapy embraces both the physical and psychological benefits of marine environments.

Other therapies listed do not focus on marine elements. Aromatherapy involves the use of essential oils derived from plants for therapeutic benefits; hydrotherapy uses water in various forms for healing purposes, such as baths or water exercises; and biorhythm therapy is centered on the idea of aligning treatments with an individual’s biological rhythms. These approaches do not incorporate the specific use of sea-based products central to thalassotherapy, which is why thalassotherapy is the correct answer.
