During an underwater massage, the massage therapist uses a hose with a powerful water jet directed at specific muscles or muscle groups to get a relaxing massage effect. The client is submersed in water up to their chest in a specialized, heated tub with hundreds of jets simultaneously applying pressure.
In Hot Stone Massage, heated stones are used as massage tools to relax and massage the muscles. This is an ancient technique with origins in China and has been used for centuries. Although it can be one of the most relaxing forms of massage, it can also be used for specific deep tissue work.
