Your neocortex, which is the thinking part of your brain, is continually sending messages to your brain stem that keep you in a fight-or-flight state. For example, your thinking mind may continually generate messages like “You are not keeping up with the competition” or “You are not being a responsible parent.” Hearing the alarm generated by your brain, your sympathetic nervous system puts your body into the tight-or-flight state, which increases your heart rate, brings tension to your muscles, and generates a host of other bodily effects.
The parasympathetic nervous system is also there, waiting to return the body to the rest-and-digest state, but if you cannot learn to quiet the messages of alarm from the neocortex, you will be left in an almost constant state of stress. Eventually, the stress response creates great wear and tear on the body, and many stress-related problems come about precisely because the brain stem is never given the chance to create balance in the body.
So how do you get around this vicious cycle? Just let the brain stem do its work. If your neocortex is constantly creating negative messages about your life and the world in general, your brain stem will continue to generate a negative response for your body.
