The text explains that your face turns red when angry because your heart beats faster to send more blood to muscles, preparing for a fight.

Infact verdict: True (88/100).

The claim that your face turns red when you're angry due to increased blood flow preparing you for a fight is supported by physiological explanations. The evidence indicates that vasodilation occurs, causing blood vessels to widen and increase blood flow to muscles and the face, resulting in redness. This is a common physiological response during anger, although the exact evolutionary purpose is not fully understood. The evidence from Stack Exchange and other sources corroborates this explanation, making the claim largely accurate.
