How Can Stress Affect our Health?

As Joe Dispenza says in his book "Evolve your Brain", whether we like it or not, once a thought happens in the brain, the rest is history. Conscious or unconscious thoughts that run through our mind daily and repeatedly create a cascade of chemical reactions that produce not only what we feel but also how we feel.
Just like the neurological stress response, the chemical response of stress can be triggered by a mere internal thought as well as a reaction to something outside of us. Here is how this process transpires: when we have a reaction to a stressor, our brain fires diverse neural nets through diverse systems. Those neural nets send a signal to a part of the midbrain called the hypothalamus. The hypothalamus is a kind of factory that takes in chemical raw materials and assembles them to produce peptides. A peptide is a chemical messenger that signals the body to turn on in some fashion.
In the stress response, the peptide made from the hypothalamus is called "Corticotrophin Releasing Hormone" (CHR). Once CHR is released, it delivers a chemical message to the pituitary gland. When the pituitary gets the signals from the hypothalamus, it makes another chemical peptide called "Andrenocorticotropic Hormone" (AHCTH). The new chemical message is now "acceptable" to the receptor sites located on the cells of adrenal glands in the body. The chemical message from the pituitary (ACTH) makes its way to the adrenal glands and it stimulates its cells to produce varios chemical called "Glucocorticoids", which further change the internal order of the body. Glucocorticoids are steroid hormones secreted by the adrenal glands. The body shuts down or limits nonessential functions like digestion, and the blood is divereted from internal organs to the muscles to prepare them for action. Our normal levels (blood preasure, heart rate, pupil dilation, chemical balance and the like) change.
Please, be aware of it !!!! You are leaving the rest of your organs defenseless. Living in stress is living in a primitive state of survival.
