Hydrotherapy Definition

Hydrotherapy is a therapeutic modality that uses water in various forms (hot, cold, steam, liquid, ice) to treat physical and psychological dysfunctions.

Physical Properties of Water

Specific Gravity: The ratio of the density of a substance to the density of water. Water has a specific gravity of 1.0 at 4 degrees Celsius, while the human body has a specific gravity of 0.974.
Density: The relationship between the substance's mass and volume. If an object has a density less than or equal to water, it will float; if its density is greater than water, it will sink.
Buoyancy: The upward thrust experienced by a body submerged in a fluid, opposing gravity. This effect is utilized to assist movements and reduce stress on joints, muscles, and connective tissue.
Hydrostatic Pressure: Pressure exerted on an immersed body by surrounding water. It increases with depth and liquid density, impacting ease of movement.
Cohesion: The inherent attraction between water molecules, resulting in increased viscosity and resistance to motion compared to air.
Viscosity: Internal friction within a liquid, resisting relative motion. The greater the liquid's speed, the higher its viscosity.
Turbulence: Irregular movement of water molecules, often created by underwater douches or turbines.
Specific Heat: The amount of energy needed to raise the temperature of 1 gram of a substance by 1 degree Celsius. Water retains heat well, approximately 1000 times more than air.

This quiz covers the fundamentals of hydrotherapy, including its definition and the physical properties of water that contribute to its therapeutic effects.
