Why do people blush?

Question

Why do people blush?

Answer 1

Because they are embarrassed.

Oh you wanted the scientific reason? Sorry :)

Answer 2

Just a part of human nature.  Blood rushes to the cheeks.  It's why they also feel warm when you blush.

Answer 3

When you're caught ashamed or in an awkward position, your body releases a bit of adrenaline. Your heart rate goes up. You breathe faster. And often, blood vessels that deliver blood to your face dilate--they open up or relax a little. More blood than usual flows to the skin of your face, and your face darkens or turns noticeably red.

Some people even have a condition referred to as erythrophobia, fear of reddening. So, there is a connection between your brain and the blood vessels that feed your face. These blood pathways are regulated by your sympathetic nervous system. In this usage, sympathetic refers to nerve signals that your brain generates unconsciously. It's your thoughts that cause these signals to be produced, but you don't consciously think about producing them. Your brain somehow sends signals to your face, based on what someone has said or what you've seen. You blush. The sympathetic nerves involved here are near the center of your spinal cord; it's the same area that controls the organs in your thorax, your chest.

Answer 4

Excitement (or embarrassment) causes an increased blood flow which is visible in the cheeks due to their close proximity to the surface of the skin.  Increased blood flow also results in higher levels of body heat which is why you may feel hot or sweat when you are embarrassed.

Answer 5

Blushing involves a sudden reddening of the face, neck and ears. Along with that normally goes an avoidance of eye contact with others and a glowing or tingling sensation over the entire body. The person blushing may even have heart palpitations or a real feeling of fear. Blushing seems to be more readily manifested among the young and inexperienced. The more worldly wise we become, the less we blush. It has also been observed that women blush more readily than men do.

Blushing is an involuntary action that is caused by ‘overlapping mental attitudes, producing embarrassment and inability to function.’ Interestingly even people who are deaf and blind blush. Helen Keller, deaf and blind from babyhood, blushed readily. One researcher commented on Keller’s blushing as follows:

Her blushing can have no relation to looks or words of disapproval, connected either with her appearance or conduct; yet she blushes just as girls do who see and hear, from the same causes, over the same parts of the body, and with the same experience of tingling.

A person can, in fact, blush when alone if they think about or read something that is embarrassing to them. These facts, then, continue to confound those who attempt to explain this phenomena.

The physical actions involved in blushing are a little easier to quantify. A confused state of mind acts upon the sympathetic nervous system. From there, the vasodilators are stimulated which causes the peripheral capillaries to expand. As a result, more blood flows to the surface of the face and neck, resulting in the reddening of the face and neck.

Animals do not blush. The reason? They are not endowed with the ability to think conceptually or to consider moral issues. Herein, therefore, lies a major dilemna for those who hold to evolution. If man evolved from lower animals, why do we alone blush?

Blushing may be instigated by any number of things. An indecent or immodest occurance, an awkward situation, a foolish blunder, or even praise that makes us stand out may trigger the blush response. We cannot control when and how often we blush. Nor should we want to. It is one of those unique characteristics that makes us human. It can, in fact, serve as a protection to us – serving as a guard to the conscience. Violating our inbuilt sense of right and wrong, may cause us to blush and this may, in turn, warn us to get back on track.

So, we need not feel embarrassed about blushing. It is a unique gift that we, as humans, have. Let's be thankful for it.

Answer 6

blush is a normal reaction to embarassment, anxiety, or excitement.! Because of the increased blood flow through the tiny vessels in your skin, your cheeks, nose, ears and neck may get flushed and turn rosy. hope i've helped =]]

Answer 7

Blushing is your body's reaction to potential danger. When you are embarassed, you try to decide "fight or flight." The blood brings more oxygen and hormones (ie adrenaline).

For humans, however, increasing the blood flow to your head and face no longer serves as an important defense; it is merely an instinctive response that has not been eliminated yet by natural selection. Another example might be getting goosebumps. It is supposed to make your hair stand on end for insulation.
