your view on the reason for blushing?Those with scientific knowledge only; are scientists any closer to finding the reason for blushing and what 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.
Adrenaline also causes your blood vessels to dilate (called vasodilation), in order to improve blood flow and oxygen delivery. This is the case with blushing. The veins in your face respond to a signal from the chemical transmitter adenylyl cyclase, which tells the veins to allow the adrenaline to do its magic. As a result, the veins in your face dilate, allowing more blood to flow through them than usual, creating the reddened appearance that tells others you're embarrassed. In other words, adrenaline causes more local blood flow in your cheeks.Those with scientific knowledge only; are scientists any closer to finding the reason for blushing and what is?
They are no closer to finding the reason for blushing - they already know the reason and are no longer looking for a reason. Once you are there, you can't get any closer. Sorry.
See the response about adrenaline for the reason.
blood rushing to your cheeks!
when we get nervous, our heart beats faster and sends more blood around the body. the red is just from all the blood flowing to the cheeks.
you'll also find you get warmer--its all an effect of the heart (blood is warmth!)
