When we are embarrassed, ashamed or shy, we blush.

Blushing is governed by our sympathetic nervous system.

Its functioning is not under our control.

I cannot control my own sympathetic nervous system?

Now, when we are ashamed or shy, it causes us immediate stress.

When something causes immediate stress, our sympathetic nervous system considers it as a threat.

To defend the threat, this system orders our adrenal glands to release a hormone called adrenaline.

It expands the blood vessels so that more
blood and oxygen can be reached to our body parts.

Thus preparing our body for fight or
flight.

Now, as the blood vessels on our face are
very close to our skin surface.

They make our face appear red, that is, we blush.
