Q. Why do we shiver when we are nervous?
Ans. It’s because when we come across a new or unexpected situation which we haven’t faced before, our adrenaline gland responds by pumping adrenaline hormone into our bloodstream to respond to that situation. Our body shakes because our mind is contemplating as to how to handle the sudden unexpected situation; whether to stand ground or run away. This action trigerred by adrenaline glands is called the fight or flight reaction.
