Contrast bath therapy involves:

Contrast bath therapy involves:

• A. The alternating immersion of an injured body part in hot and cold water baths.
• B. Immersion in hot water only.
• C. Immersion in cold water only.
• D. Massage and heating pad.

Answer: (A)

Contrast bath therapy relies on temperature cycling to stimulate circulation. By alternating immersion in hot water, which causes vasodilation, with cold water, which causes vasoconstriction, you create a pumping action in the local vessels. This repeated vasodilation and vasoconstriction helps move fluid and inflammatory byproducts out of the area, increases tissue perfusion, and can reduce edema, pain, and stiffness after an injury. It’s different from soaking in hot water alone (pure heat therapy), cold immersion alone (cryotherapy), or modalities like massage with a heating pad, which don’t produce the same alternating vascular pump effect.
