When you are chronically stressed the sympathetic system is turned up high and the parasympathetic is down low...so your brain, emotions, hormones and body is in a state of constant fight/flight...the stress state that is literally poisoning you with stress chemicals and creating all the symptoms of stress. Now the good news, which is the second secret is that you do have this built-in relaxation system and you can turn it up and turn down the stress system.
