Why do some people blush?

why do i blush when i get embarrassed or im around a girl i like? what can i do to stop it, its very embarassing!!Why do some people blush?
From a physiological standpoint, blushing occurs in the face because, per square millimeter, facial skin has more capillary loops, as well as more vessels per unit volume than other parts of the body. Also, the cheeks' blood vessels tend to have a wider diameter and are closer to the surface of the skin. The fluid in the tissue of the cheeks don't tend to obscure the blood vessels as much as in other parts of the body. When the body is faced with stress, the “fight or flight” responses kicks in and releases the extra adrenaline that stimulates the sympathetic nervous system to cause facial blushing.





btw the same thing happens to me when im up in front of the class or my friends start talking about the guy i likeWhy do some people blush?
It's natural and you can't stop it really, just keep calm. It's your body's way of reacting to people laughing at you( or something along those lines ) and your body rushes your face with blood, i have the same problem..no cure.
It's an adrenaline rush in your system; virtually impossible to control, the more you try, the more you cannot!
its part of growing up your body starts to do different things that you might not be used to.
i kno rite?!!! its natural... nothin u can do... lol. it is embarrasing sometimes!
WHEN U GET NERVOUS BLOOD RUSHES 2 UR HEAD!!
