Sleeping in a closed room with a fan running causes death through hypothermia or asphyxiation.
Fan death is a Korean urban legend without scientific basis. Fans circulate air; they don't lower body temperature to dangerous levels or deplete oxygen. Thousands sleep with fans without incident. Belief persists due to cultural tradition.
