It shows their feelings and reactions.Why do people blush?
natural emotions
Blushing is a unique blend of evolutionary and social behavior. It's an involuntary reaction of the sympathetic nervous system, which is responsible for our ';fight or flight'; response, but blushing is solely triggered by social cues.
People generally blush when they're feeling embarrassed, scared, or stressed. As a result of the ';fight or flight'; response, the capillaries that carry blood to the skin widen, and the increased blood flow lends the face, as well as sometimes the chest, neck, or even the body or legs, a reddened color.
Excessive facial blushing, or erythrophobia, is caused by overactivity of the sympathetic nervous system. The condition can cause a lot of psychological duress and has engendered several support groups.
It's common knowledge that animals don't blush. So while there are some evolutionary cues behind blushing, it's also linked to something uniquely human -- moral consciousness.
something causes the blood preasure to rise, increasing blood flow to the face/other parts of the body.... but u most notice it there.
Embarrassment mainly.
some sort of emotional response to stimuli
Blushing is a reaction triggered by the brain that sends blood to the face. It is similar to sweating.
