Answer:
When you're embarrassed, your body releases adrenaline. ... As a result, the veins in your face dilate, allowing more blood to flow through them than usual, creating the reddened appearance that tells others you're embarrassed. In other words, adrenaline causes more local blood flow in your cheeks.
Explanation:
You can no more stop blood rushing to your face than you can will your lungs to stop breathing air or your heart to stop pumping blood.
Blushing is part of your body’s “fight-or-fight” mechanism, which is the way your body responds in an emergency. To direct all available energy to your muscles in an emergency, you need your heart rate and your breathing rate to increase to deliver as much oxygen as possible to your muscles and organs. You’ll likely benefit from seeing more acutely, so you need your pupils to dilate to let in more light.
Adrenaline is responsible for all of these emergency response measures. The body’s natural stimulant, adrenaline increases your breathing rate, and causes your pupils to dilate. It also causes the blood vessels deep in your muscles to dilate, in order to get more oxygen and more energy where it’s needed most. The veins in your face also dilate. As they open up allowing more blood to flow, your cheeks become warmer and redder. You’re blushing.
