Suffering cascades through your body via the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal axis (HPAA) of the endocrine (hormonal) system. Let’s unscramble this alphabet soup to see how it all works. While the SNS and HPAA are anatomically distinct, they are so intertwined that they’re best described together, as an integrated system. And we’ll focus on reactions dominated by an aversion to sticks (e.g., fear, anger) rather than a grasping for carrots, since aversive reactions usually have a bigger impact due to the negativity bias of the brain.
