Hydrotherapy can be broken down into three key components: Heat, Buoyancy, and Massage.
During exercise or strain on the muscles, lactic acid is produced. Lactic acid removal is sped up by heat, allowing the muscles to become less fatigued and recover faster. Additionally, moving hot water increases this effect by increasing heat conduction.
Buoyancy is an upward force exerted by a liquid, gas or other fluid that opposes the weight of an immersed object. When submerged, there is less pressure on the body, tissues, and muscles.
Massage is the manipulation of superficial and deeper layers of muscle and connective tissue to enhance function, aid in the healing process, and promote relaxation and well-being.
