"ice pack"的定义和意义

What is an "ice pack"?

An ice pack is a portable, reusable pouch filled with gel or ice cubes that is applied to injuries or sore areas of the body to reduce swelling and relieve pain. It is commonly used to numb pain, minimize swelling, and encourage healing after minor injuries like bumps, sprains, or muscle strains. Ice packs can be kept in a freezer and are wrapped in a cloth or towel before being applied directly to the skin to prevent frostbite. They provide an easy way to apply cold therapy for quick relief.
