  • Everybody feels embarrassed at times but nothing quite emphasizes the feeling, like a completely red face.

  • So the blushing serve a functional purpose, or as simply to embarrass you further.

  • Blushing is an involuntarily and uncontrollable reflex caused by the sympathetic nervous system, which activates your fight or flight response.

  • The release of adrenaline speeds up your heart rate and breathing, dilates your pupils and redirect energy to your muscles.

  • All these effects contribute to the feelings you experience when embarrassed.

  • the ones in your face do.

  • But this effect is entirely exclusive to humans.

  • The scientists still out on this one; even Charles Darwin commented that blushing is

  • "The most peculiar and most human of all expressions."

  • But there are some scientific theories into why we blush.

  • within the social codes of human society.

  • ,which can be controlled or faked.

  • To the people who see you blush, they understand from experience what you're feeling.
