Every morning, before we get out of bed (at about 4 or 5am) our bodies begin to secrete hormones into the blood that prepare us to awaken. Stress-response hormones like epinephrine, norepinephrine and cortisol (the fight or flight) hormones enter your bloodstream and cause an increase in your blood sugar. This increased blodo sugar from your liver is going to be used by your body as the fuel to get you going until you eat breakfast. Your nervous system has to coordinate the release of all these chemicals at the precise time, and in the correct quantity, so that you can wake up and make it to work on time. Without a healthy nervous system, this does not play out like a well-trained symphony and will instead make your body off-key and out of tune.
