Why do girls fan themselves when they are aroused?

Girls may fan themselves when aroused due to an increase in blood flow to the skin, causing a sensation of warmth. This physiological response is known as vasodilation, where blood vessels widen to allow more blood to flow through, leading to a feeling of increased body temperature. Fanning themselves can help dissipate some of this heat and provide a temporary sense of relief. Additionally, the act of fanning can also serve as a subtle and socially acceptable way to cool down and regulate body temperature in public settings.
