Hand warmers were first used in ancient China, where small metal containers filled with burning charcoal were employed to keep hands warm. This practice spread to other cultures, including Japan and Europe, where various forms of hand warmers were developed over the centuries. The modern disposable hand warmer, utilizing chemical reactions to generate heat, was popularized in the 20th century.
