What is bed warmer?

A bed warmer is a device used to heat up a bed before getting in to ensure a warm and comfortable sleeping experience. These devices are typically filled with hot water or heated stones and placed in the bed to warm it up. They have been used for centuries, with historical examples including metal pans filled with hot coals or bricks.

Modern bed warmers may use electric heating elements or microwavable packs to heat them up quickly and safely. Some bed warmers are designed to be placed under the sheets to warm up the entire bed, while others are used to warm up specific areas like a cold spot in the bed.

Bed warmers can help improve sleep quality by creating a cozy and inviting sleeping environment, especially during cold winter nights. They are also commonly used to alleviate muscle tension and promote relaxation.
