What do you call a folded wet or dry cloth applied firmly to a body part?

A folded wet or dry cloth applied firmly to a body part is known as a compress. This term specifically refers to the use of cloth, often gauze, that may be dampened with water or a medicinal solution, and is used to provide pressure, reduce swelling, or apply heat or cold to the affected area. Compresses are commonly used in first aid to help alleviate pain or treat injuries by allowing for proper blood circulation and tissue recovery.

In contrast, a dressing typically serves the purpose of covering wounds to protect them from infection and facilitate healing, while a bandage is used to secure a dressing in place or provide support for an injured limb. A wrap often refers to a type of bandage or elastic material used to cover an area but does not imply the specific therapeutic function associated with a compress. Therefore, the term compress uniquely identifies this method of treatment through the application of a cloth to exert pressure.
