Hot stone massage is a natural therapy in which warmed stones are positioned on parts of the client’s body of to maximize the effect of the massage. The stones used are typically river rocks or other very smooth-surfaced stones made of basalt. These stones are heated in sanitising water before use. The high iron content in basalt helps the stones retain heat during the massage. Hot stone massages are beneficial on both physical and psychological levels. The heat relaxes muscles deep down creating conditions which make stretching and toxin release more effective. Always check with your doctor before getting a hot stone massage; individuals with certain conditions–including pregnant women and people with high blood pressure-are advised to avoid this type of therapy.
