Watsu is a form of aquatic bodywork used for deep relaxation and passive aquatic therapy. It was developed by Harold Dull at Harbin Hot Springs, California in the early 1980s and combines elements of muscle stretching, joint mobilization, massage, Shiatsu, and dance, performed in chest-deep warm water (around 35°C = 95°F). The term "Watsu" comes from the words "water" and "shiatsu," with shiatsu being a type of traditional Japanese massage that uses acupressure to promote relaxation.
During a Watsu session, a practitioner or therapist gently cradles, moves, stretches, and massages a receiver in the warm water. The receiver is continuously supported by the practitioner while being backfloated, rhythmically cradled, moved, stretched, and massaged. Watsu is typically performed in a peaceful setting with soothing music to enhance relaxation.
Watsu is used for various purposes, including deep relaxation, pain and tension relief, and enhancing flexibility. It is practiced in spas, clinics, and hospitals and is also utilized as an aquatic rehabilitation technique. The therapy has been proven to help relieve conditions such as arthritis, fibromyalgia, and stress-related disorders.
