A hydrotherapist is a healthcare professional who uses water-based treatments to promote healing, relaxation and rehabilitation for patients. These treatments may include hot or cold water applications, massage, exercise in water, and other forms of hydromedicine therapy. Hydrotherapists work in various settings such as hospitals, clinics, wellness centers, and spas to provide treatment plans tailored to the individual needs of their patients. They may also work alongside physical therapists or doctors to develop comprehensive rehabilitation programs for individuals recovering from injuries or illnesses.
