The axis of stress (or yoga gloves and socks [HPA] axis). When someone suffers a stressful event, his rate of glucocorticoids in the blood increases. This brings about, via specific receptors situated in the hippocampus, an activation of the hypothalamus, which then secretes corticotrophin-releasing hormone (CRH). This hormone, in turn, activates the pituitary gland (or hypophysis) to produce ATHC (adrenocorticotropine), which circulates in the blood system and reaches the suprarenal glands, where they provoke the release of cortisol.
The activity unleashed by the catecholamines allows all of the reactions produced by the axis of stress to draw from energetic resources of the body by metabolizing lipids and sugars. In activating the hypothalamus, this circuit makes it possible to draw more deeply from the organism’s reserves.
Other layers of the central nervous system, situated underneath the hypothalamus, can also activate the adrenal glands. These regions are situated in the medulla, the marrow, and some reflex pathways. A lack of adrenaline in the blood can also activate the adrenal glands via the mechanisms of homeostatic regulation. The hypothalamus can be influenced by other centers of the brains, especially those that govern perceptive and cognitive analysis or the emotions.
This phase of stress is considered to be constructive because it predisposes the organism to become creative. If a resting phase (a small cup of tea) ensues, the organism restores its forces.
The Stress Reaction. The stress reaction varies in intensity according to (a) the danger and (b) the way the stress is felt by the mechanisms that regulate the reaction. Richard S. Lazarus (1991) analyzed how certain mental reactions could activate or deactivate a stress. He sought to define the means with which to cope with stress. Selye thought that the axis of stress, once it was activated by a mechanism that is still not well understood, reacted in an undifferentiated manner. Since research has shown that the vegetative system is less autonomousâ than was believed, this statement has been marginalized. the organization of the defenses against exhaustion . If the Organism is repeatedly placed under stress, the axis of stress runs out of easily available resources. To continue to function, it sets about to draw from those resources that are more difficult to use and activates mechanisms that slow down the reactions of exhaustion.
The organism sets itself up in a state of accommodation to the shock. The HPA axis is reinforced by an increase of chemical activity that doubles the activity of the sympathetic nervous system. The activation often begins with the hypothalamus, which recruits the help of the pituitary gland this time. The pituitary then secretes corticoliberin, which will produce a hormone called adrenocorticotrophic hormone (ACTH), also known as corticotropin. ACTH activates yet a greater number of the adrenals, which in turn, among others, will activate the corticoadrenal hormones, which are released by the paraventricular nucleus (PVN) of the hypothalamus. It then activates the adrenal gland, which will release hormones such as the glucocorticoids, like cortisol and cortisone. These hormones mobilize the reserves available in the form of carbohydrates and add slowâ sugars into the blood. They inhibit the antiallergic and antiinflammatory manifestations caused by the damage to the tissues during the stress reaction by diminishing the activity of the immune system (especially eosinophils).
At the moment when this system becomes established and can no longer be curbed, there will be permanent vasodilation in the organs necessary for a reaction of fight or flight and a permanent vasoconstriction in the organs dependent on the parasympathetic circuit. This vasoconstriction is in part noxious to the tissues that depend on it and impedes the disposal of the metabolic waste produced by the muscles in permanent tension:72
We were brought to consider the shock syndromes no longer as an exhaustion of the means of defense; but, to the contrary, as a consequence of their activation and of the persistence of their action in the case of the ineffectiveness of flight or fight. (Laborit, 1994, 2.2.2, p. 236; translated by Marcel Duclos) the exhaustion reaction. The large consumption of carbohydrates reduces the production of other substances that depend on it, like serotonin. As we have seen, a reduction of serotonin can produce depressive and suicidal tendencies. These tendencies sometimes are linked to bulimic crises which seek to compensate for the lack of production of substances like serotonin. Stress can manifest through two distinct mechanisms:
1. A mental stress, associated to negative and biased representations of the situation.
2. A vegetative stress that exhausts the physiological resources of the organism.
Best yoga gloves and socks for A chiao of three, five, or seven days is still celebrated in Taiwan. There are other chiao rites for the ordination of priests, the birthdays of gods, and the warding off of disasters. All chiao are celebrated on two levels a feast in the village and a liturgy inside the closed temple. Incense-burning plays a significant role in the celebration of rituals. An incense burner is the central object in temples and is an essential part of all Taoist rites. Welch, Holmes, and Anna Seidel, eds. Facets of Taoism.
