Massage involves working and acting on the body with pressure – structured, unstructured, stationary, or moving – tension, motion, or vibration, done manually or with mechanical aids. Massage can be applied with the hands, fingers, elbows, knees, forearm, feet, or a massage device. Massage can promote relaxation and well-being, can be a recreational activity, and can be sexual in nature .
In professional settings massage clients are treated while lying on a massage table, sitting in a massage chair, or lying on a mat on the floor, while in amateur settings a general purpose surface like a bed or floor is more common. Aquatic massage and bodywork is performed with recipients submersed or floating in a warm-water therapy pool. The massage subject may be fully or partially clothed or unclothed.
