1. Why Do People Blush When They Feel Shy?

When people feel shy, they blush. Why is that? The red comes from an increase of blood to the face because of the dilatation of the blood vessels. When a person feels shy or sees a stranger, he or she is usually nervous. Then, the nerves which control the heart and blood vessels get excited. So the heart beats faster and the blood vessels on the face dilate. This causes more blood to go to the face. That is why the face turns red when a person feels shy.
