Hot stone massage therapy uses heated stones to naturally loosen and relax the muscles. The stones are placed in certain areas of the body for maximum relief. The typical stones that are used are usually smooth, flat, river rocks. The stones are heated in warm sanitizing water. Basalt stones are the best to use because they have a high iron content. These stones hold heat the longest. The heat from the stones warms and relaxes the muscles making it easier for the therapist to effectively work those muscles. Hot stone massage was even used by Native Americans. They used to heat stones by the fire to treat aching muscles. This massage provides great benefits for physical and mental health.
