What is the primary function of an artificial ice pack?

The primary function of an artificial ice pack is to provide localized cold therapy. Cold therapy is widely used in athletic training and rehabilitative settings to help reduce swelling and inflammation, numb pain, and minimize tissue damage following acute injuries. The cold temperature constricts blood vessels (vasoconstriction), which decreases blood flow to the affected area, thereby limiting the accumulation of fluid and reducing inflammation.

Using an ice pack effectively can also relieve muscle spasms and delay the onset of delayed onset muscle soreness (DOMS) after exertion. The targeted application of cold to specific areas helps manage pain and promotes recovery, which is critical for athletes returning to their sport or activity.
