Before you arrive, the massage therapist sanitizes the stones and heats them in 120 and 150 degree water. A massage therapist uses traditional strokes of Swedish massage while holding a heated stone. As the stone cools, the therapist replaces it with another. The therapist might also leave heated stones in specific points along your spine, or in the palms of your hand, or even between your toes to improve the flow of energy in your body. If you have inflammation or muscle injury, cold stones are sometimes used.
