Stress can alleviate pain – perhaps the only good thing about it most would suppose. This “stress-induced analgesia” shields the body from pain after a serious injury and acts as a protective mechanism. Long known to operate through a mechanism in which the body releases its own naturally occurring cannabinoids, recent research indicates the action of the stress hormone noradrenaline as an additional mechanism.
Processes that mediate the emotional and stress-related aspects of pain originate in the amygdala and are controlled by neurons that originate in the brainstem and are regulated by noradrenaline. Noradrenaline appears to modulate pain inputs in the amygdala by limiting neuro transmissions (the mechanism by which one neuron triggers a nerve impulse in another) from the brainstem.
This protective response is akin to other amygdala and brainstem-mediated survival responses – sleep deprivation and increase in emotional response, handling surprise, and the focus of attention on emotion among many. It is useful.
To reiterate a point – understanding of our brain’s physiological processes allows us to manage behaviours without reducing their protective effectiveness. For example, anger has survival benefits. Yet anger also flairs at inappropriate times and in inappropriate ways. A mistaken run up the ladder of inference produces a threat response where none is warranted. It is times like these when the brain’s physiological responses are appropriate but the situation that prompted them is not. And it is this cognitive management without the loss of emotional richness and survival protection that is one ongoing aspect of coaching TED.
