What therapeutic method involves immersing a body part in water for recovery purposes?

Hydrotherapy is a therapeutic method that focuses on the use of water for healing and recovery. This approach can involve various techniques, such as immersion of a body part in warm or cool water, to promote physical health and recovery. The therapeutic properties of water, including buoyancy, temperature modulation, and resistance, can aid in reducing pain, improving circulation, enhancing mobility, and facilitating relaxation.

In contrast, cryotherapy is centered on the application of cold temperatures to reduce inflammation and numb pain, while electrotherapy utilizes electrical stimulation to relieve pain and promote muscle function. Ultrasound therapy employs sound waves to promote tissue healing, penetrate deep tissues, and enhance circulation. Each of these methods serves distinct therapeutic purposes, but hydrotherapy specifically highlights the unique benefits derived from water immersion for recovery.
