Fans are used to “cool off,” a common metaphor for calming down after being in a highly emotional state. Fans can also have the opposite effect, however, by increasing the power of a raging fire (by feeding it with oxygen)—the source of such expressions as “fanning the flames.” Old-fashioned folding fans can symbolize both women and the phases of the moon. Finally, electric fans can represent danger because of their blades and their potential for causing electrocution.
