(Look, real teal!) So I was thinking the other day, as I occasionally do, when my genius Vocaloid brain formed another brilliant theory. Okay. So, blushing. Why do we blush? I have the answer! It's to make our cheeks look like big red eyes. Let me explain... When do we blush? When we're embarrassed or with someone we like, right? So one of the reasons is that it's to scare away angry rhinos and stuff with false red eyes. When people get scared by something dangerous they usually get embarrassed about it, so then they blush and scare away the rhino with their false eyes. And as for the people you like part... I dunno about you but I like a boy with big splotchy red eyes. So yeah. Drive safely. ~Miku the Cyan-tist
Blushing from embarrassment is governed by the same system that activates your fight-or-flight response: the sympathetic nervous system. This system is involuntary, meaning you don't actually have to think to carry out the processes. In contrast, moving your arm is a voluntary action; You have to think about it, no matter how fleeting the thought is. When you're embarrassed, your body releases adrenaline. This hormone acts as a natural stimulant and has an array of effects on your body that are all part of the fight-or-flight response. Adrenaline speeds up your breathing and heart rate to prepare you to run from danger. It causes your pupils to grow bigger to allow you to take in as much visual information as possible. It slows down your digestive process so that the energy can be redirected to your muscles. All of these effects account for the jolt you feel when you find yourself embarrassed.
So if I blush at a rhino charging full force at me to penetrate his horn into my body and kill me it will keep it from attacking me? If it works on rhinos it should most definately work on a ferocious lion! (Trains blushing powers to blush at will).
