Bandages are medical supplies used to cover and protect wounds or injuries. They help keep the area clean, prevent infection, and promote healing. Bandages come in various types, including adhesive strips, gauze pads, and elastic wraps, each designed for specific uses. When applying a bandage, it is important to clean the wound first and ensure the bandage fits snugly but not too tight. Proper use of bandages can aid in recovery and reduce the risk of complications. They are commonly found in first aid kits and are essential for treating minor injuries at home or in medical facilities.
