When you are subjected to stresses, whether they are mental stresses such as a phobia or environmental such as extreme heat, your brain sends signals throughout your body to prepare it to face whatever survival challenges that the stress may pose. In a way, it is as if your body is preparing for war. It knows that there is a threat, because you are feeling stressed. Therefore, the mind sets up its defences in order to protect its host -- the body.
