coldpack

A cold pack is a device or material used to deliver cold therapy to a specific area of the body. It aims to reduce pain, swelling, and tissue damage after injuries or surgical procedures. Cold packs typically work by removing heat from the treated area, either through chilling or a chemical reaction.

Two common types are reusable gel packs and single-use instant cold packs. Reusable packs contain a gel or liquid inside a durable shell and are cooled in a freezer before use. Instant cold packs are sealed and activated by bending or crushing, producing an endothermic reaction that creates cold temperatures.

Applications include acute injuries such as sprains and strains, contusions, post-operative swelling, dental procedures, and delayed-onset muscle soreness after exercise. Proper use involves placing a thin cloth between the skin and the pack, applying for about 15 to 20 minutes, and taking breaks between applications to avoid frostbite.

Safety and precautions: do not use cold packs on numb or poorly perfused skin, open wounds, or areas with sensory loss. Avoid prolonged contact and discontinue if skin becomes pale, blue, or excessively white. Do not place ice directly on the skin, and never apply heat to a cold pack. Check packaging for manufacturer’s instructions.
