Some more ideas about what happens with stress!!

How stress takes it toll...
A stress response starts in the brain.  The lower reactive part of the brain will kick in.  The hypothalmus, amygdala, and pitutiary gland, all go on alert.  They communicate to send signals to the rest of the body to prepare for flight, fight, or freeze.  Then the body releases hormones, some to the adrenal glands called adrenaline.  This makes the heart pump faster, and the lungs work harder to flood the body with oxygen.  The adrenals also release cortisol and glucocorticols which help the body to release sugars for quick energy.  Nerve cells release norepinephrine which tenses the muscles and sharpens the senses to prepare for action.
When the threat passes, epinephrine and norepinephrine levels drop.  However, if the threat happens too often then the arteries can be damaged.  Chronic low levels of stress keeps the glucocorticols in circulation which can lead to a weakened immune system, loss of bone mass, suppression of the reproductive system and memory loss.
So the cure, which is not always easy, is to remain calm.  Learning to relax is important.
LENS neurofeedback helps the brain to reset to a more calm, relaxed, less reactive state.
