What is a cold compress?

Cooling an injury like a sprain or bruise can help to reduce the swelling and pain. There are two types of compress: ice packs, and cold pads, which can be made from dampening a cloth with cold water.

How to use a cold pad


  1. 1

    Soak a clean cloth or flannel in cold water. Then wring it out lightly and fold into a pad.

    • Hold it firmly against the injured area.

  2. 2

    Re-soak the cloth every couple of minutes to keep it cool.

    • Do not cool the injury for more than 20 minutes.

How to use a ice pack

  1. 1

    Use a pack of frozen vegetables or partly fill a plastic bag using small ice cubes or crushed ice. Wrap the bag in a dry cloth.

  2. 2

    Hold the pack on the injury and top up with ice to keep it cool.

    • Do not cool the injury for more than 20 minutes.
