A rare medical condition where a person sweats blue-colored sweat, caused by the presence of a blue pigment (usually from bacteria or ingested substances) in the sweat glands.
From cyano- (blue) + -drosis (from Greek hidros, sweat). This medical term literally means 'blue sweating' and is used by dermatologists to describe this unusual phenomenon.
Cyanidrosis sounds like science fiction, but it's real—people have actually sweated blue, usually from infections with chromogenic bacteria or from ingesting certain dyes, and it shocked the medical community when they first documented it.
