  • Topic: Blushing.

  • Why do we blush?

  • I don't know.

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

  • Blushing is governed by our sympathetic nervous system.

  • Its functioning is not under our control.

  • What?

  • I cannot control my own sympathetic nervous system?

  • Absolutely.

  • 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.

  • Adrenaline speeds up our breathing rate.

  • 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.
