Hot stones (usually basalt) are placed into an electric heater which is filled with water. The water is gently heated.
Once the stones have heated sufficiently, some are placed onto specific points on the body (such as the back, hands, etc.) and others are held by the massage therapist and used to work the muscles.
Combining hot stone protocols with a full body massage provides a very healing and effective experience. The hot stones also expand blood vessels, which encourages blood flow throughout the body. The hot stones have a sedative effect that can relieve chronic pain, reduce stress and promote deep relaxation.
