why do we blush???

any scientific reasons......​

Answer 1

Answer:

Physiologically, blushing occurs when an emotional trigger causes your glands to release the hormone adrenaline in your body. Adrenaline's effect on your nervous system causesthe capillaries that carry blood to your skin to widen. Since blood is then brought closer to the surface of the skin, it causes you to blush.

SCIENCE explains blushing as a reaction of the sympathetic nervous system and part of our “fight or flight” response. When you're embarrassed, adrenaline is released, speeding up your heart rate and dilating your blood vessels to improve your blood flow and oxygen delivery.
