Thalassotherapy utilizes which of the following?

Thalassotherapy is a therapeutic practice that specifically involves the use of seawater and marine products for health and wellness benefits. This technique is based on the idea that the minerals and trace elements found in seawater can have positive effects on the body, including improving circulation, relieving stress, and promoting skin health.

In thalassotherapy treatments, various marine ingredients such as seaweed, algae, and mineral-rich sea salts are utilized. These elements are known for their soothing and revitalizing properties, which can aid in the detoxification process, enhance skin hydration, and provide overall relaxation.

The other options involve different therapies that do not align with the principles of thalassotherapy. Freshwater and minerals relate more to traditional hydrotherapy, while cold compresses and ice packs are often used for acute injuries or inflammation, and herbal infusions and teas are associated with herbal medicine rather than the sea-based methods of thalassotherapy. Therefore, utilizing seawater and marine products is the core of thalassotherapy, making it the correct answer.
