HOT WATER BOTTLE (DID)

A hot water bottle is a portable container, usually made of rubber, silicone, or thermoplastic, that is filled with hot (but not boiling) water and sealed with a stopper. It is used to provide warmth, relieve muscle aches, reduce cramps, and ease joint pain. Hot water bottles are also commonly used to keep beds warm during cold weather. Proper use involves avoiding boiling water and ensuring the bottle is not overfilled to prevent leaks or burns
