Why do we Blush? | #aumsum #kids #education #science

AumSum was answering a question in class when everyone suddenly turned to look at him. His cheeks grew warm, and within seconds they turned bright pink. Embarrassed and confused, he wondered - Why do we Blush? Determined to find out, AumSum shrank and entered his own body. AumSum landed in a region deep within his brain called the hypothalamus. It was reacting to the sudden attention and strong emotion AumSum had felt just moments earlier. The hypothalamus sent out commands through the nerves, activating a special part of the nervous system that controlled automatic reactions in the body. AumSum zoomed back to the face and saw the message arrive. The tiny blood vessels beneath his skin began to widen. This widening process was called dilation. As the vessels expanded, more warm blood flowed into them. The skin above the vessels began to glow pink, then brighter, creating the blush. AumSum also saw that blushing didn’t happen everywhere. The skin on the face, especially the cheeks, had many sensitive vessels close to the surface. That made the color change more noticeable here than on other parts of the body. Smiling proudly, AumSum now understood the mystery.
