Hot stone massage is a specialty massage where the therapist uses smooth, heated stones as an extension of his or own hands, or by placing them on the body. The heat can be both deeply relaxing and help warm up tight muscles so the therapist can work more deeply, more quickly.
Most spas offer their own versions of hot stone massage, but they might call it lava stone massage, river rock massage, or warm stone massage. A hot stone massage, however, takes a lot of skill and sensitivity on the part of the therapist.
