What is the recommended duration for a cold pack application?

• A. 5 minutes
• B. 15 minutes
• C. 30 minutes
• D. 10-20 minutes, longer if over bandage or cast

Answer: (D)

Cold therapy should cool enough to help reduce pain and swelling without risking skin injury. For direct skin contact, a typical safe window is about 10 to 20 minutes. When there’s a barrier between the cold pack and the skin—such as a bandage, wrap, or cast—the heat transfer is reduced, so you can extend the duration beyond 20 minutes to achieve the same cooling effect deeper or through the barrier. Always watch for signs of overcooling like numbness, pale or blotchy skin, or a burning sensation, and stop the treatment if those occur. Use in short cycles and follow clinical guidance on how often to apply.
