Put wet rag on ice and let it get cold. im not sure if that's what you meant but that's what a cold rag is. cold rags are useful for things like heat related illnesses by placing cold rags on major veins and arteries to cool a person down like wrists, neck and ankles. cold rags are also useful for relief of itchy eyes due to Allergies. cold restricts blood vessels and can stop the itching.
