Stone massage is a type of therapeutic massage that involves the use of smooth, heated stones. The stones, which are typically made of basalt, a type of volcanic rock, are heated to a specific temperature and then placed on specific points on the body. An LMT may also use the stones as a massage tool, using them to apply pressure and manipulate the muscles. The heat from the stones helps to relax the muscles, increase circulation, and promote deep relaxation. The massage therapist will typically use a combination of techniques, such as Swedish massage and reflexology, during a stone massage session.
