Robert Sapolsky, PhD wrote in Scientific American (8/10/03):“a rat will be less likely to develop an ulcer in response to a series of electric shocks if it can gnaw on a bar of wood throughout, because it has an outlet for frustration. A baboon will secrete fewer stress hormones in response to frequent fighting if the aggression results in a rise, rather than a fall, in the dominance hierarchy; he has a perception that life is improving. A person will become less hypertensive when exposed to painfully loud noise if she believes she can press a button at any time to lower the volume; she has a sense of control.” Intense exercise is very much a control. Triggering the sympathetic nervous system (SNS) we release catecholamines, cortisol and glucocorticoids to ready our body for action. But it also reclaims conscious control of stress activation of the SNS. Intense exercise then releases dopamine which brings satisfaction and helps you enjoy physical activity (positive stress, called eustress) to combat the chronic stress (negative stress, called distress), which allows you to do your long cool down yoga after and restore your rest and relax reflex of the parasympathetic nervous system. Activating the PNS releases acetylcholamine which blunts and turns off your sympathetic alarm system, so you can restore function to the five major systems of your body which are suppressed from SNS activation: gastrointestinal, immune, neural, cardiovascular and endocrine. It allows us to sleep well which gives us full recovery. We regain control of our lives and restore our health. It is our process of oscillating readiness and relaxation; our gnaw bar, our hard-fought reclaimed dominion, our button we push for intrinsic locus of control...
