Why do you blush when you are shy?

In fact, blushing is the command of the mind. It turns out that our visual and auditory nerves are concentrated in our minds. When we see and hear things that make us shy, our eyes and ears will immediately transmit the news to the cerebral cortex, which will stimulate the adrenal gland in addition to contacting the relevant parts. When the adrenal gland is stimulated, it will respond immediately and secrete adrenaline. Adrenaline has a characteristic. When it is secreted in a small amount, it can make the blood expand without reflux, especially the subcutaneous small blood vessels of the face. But when it is secreted in large quantities, it will cause vasoconstriction.

When we feel embarrassed, it is the cerebral cortex that stimulates the adrenal gland and secretes a small amount of adrenaline, so our faces are hot and red. Not only will you blush when you are shy, but you will also blush when you are happy and angry. When you are extremely angry, your face is not only red, but also red and You Lan, and sometimes it turns pale. This is because the adrenal gland is secreted in large quantities, which makes blood vessels contract, alternately hyperemia and anemia, or makes blood vessels in a state of anemia for a long time.

In fact, it is very simple to overcome blushing. Just when you see something that excites you, try to make your mood as calm as water, then make more new friends, participate in more social activities and communicate with strangers.
