The stones are immersed in water and heated in an electric heating device until they are within a certain temperature range. The stones may be placed at specific points on the back, in the palms of the hand, or between the toes.
The heat warms and relaxes the muscles, which allows the therapist to apply deeper pressure, if desired.
The warmth of the hot stones improves circulation and calms the nervous system.
And massage therapists can place stones on points that are thought to be energy centers of the body to rebalance the body and mind.
