Blushing results from an increase in superficial facial blood volume: blood vessels in the skin dilate, and red blood cells color the skin red. The area of skin that can blush is usually restricted to the face, ears, and neck, and in rare cases, the upper body. This dilation of the blood vessels is involuntary. Stress can increase the activity in the autonomic nervous system. Blushing appears to be an involuntary sympathetic nervous system response.
Blushing starts at three years of age. At that age we become aware that others can observe us. Most people, however, do not remember blushing before the age of five. Normally, the intensity and frequency of blushing peaks in teenage years and decreases with age. However, even very old people can blush, and the amount of blushing varies greatly between individuals.

A sudden rush of blood caused by the dilation of blood vessels running superficial to the skin surface. This is caused by an emotion which causes chemicals to be released in the brain. It is a rather complicated process.

addrenalin is released speeding the heart rate, pumping blood quicker, expanding all your blood vessels, making them more visible on the surface

if youre embarrassed or excited, your heart quickens, your blood pressurequickens, and therefore, blood rushes to where there are most pulmonary vessels- your face andchest.

getting embarrassed makes your heart beat faster and pumps adrenaline round your body. when your heart beast faster, more blood reaches the skin and faster. thus, you look redder than usual!!
