What causes blush on face?
This natural reaction occurs in the face of a perceived threat, and it can also be triggered by the onset of a powerful emotion such as stress, shame, or embarrassment. Blood vessels in the face get wider and increase blood flow to the skin, which leads to the characteristic redness of blushing.
