Steps to Elicit the Relaxation Response. The following is the technique reprinted with permission from Dr. Herbert Benson's book. The Relaxation Response. The Relaxation Response is a natural innate protective mechanism which allows us to turn off harmful effects from stress through changes that decrease heart. The term, 'Relaxation Response' was coined by Dr. Herbert Benson, book The Relaxation Response, Dr. Benson describes the scientific.

Uploaded by Alethea Bowser on February 23, The relaxation response RR is a mind-body intervention that counteracts the harmful effects of stress. During situations perceived as being acutely stressful, the 2 main pathways activated are the sympatho-adreno-medullary SAM axis and the hypthothalamus-pituitary-adreno HPA axis.
Both axes are activated by the hypothalamus secreting corticotrophin-releasing hormone CRH , which causes the pituitary gland to release adrenocorticotropic hormone ACTH. In the more rapidly acting of these pathways, the SAM axis, ACTH stimulates the adrenal medulla to release the catecholamines epinephrine and norepinephrine.
Once in the bloodstream, cortisol induces metabolic changes in the liver, resulting in increased glucose concentrations in blood and tissues.
The increased glucose produces adenosine triphosphate ATP to repair damaged cells and enables metabolically active cells throughout the body to respond to the stressor. To date, most studies of RR-related biochemical changes have examined those that occur over periods of weeks or months and, thus, fall outside the scope of this review.
Researchers examining potential relationships between the RR and HPA changes have tended to focus on the release of cortisol. However, their studies differ in the methods of measurement, the time of day the studies took place, and the extent of participant experience with eliciting the RR. To control for these variations, we selectively reviewed only those studies that measured acute changes in serum cortisol levels while controlling for diurnal rhythms.
Sudsuang and colleagues found Buddhist monks had significantly lower serum cortisol levels following a period of meditation than did members of a nonmeditating control group. Nitric oxide is a short-lived nitrogenous free radical that has been shown to mediate diverse physiological processes including cardiovascular, immune, and nervous system function. These include the measurement of NO in exhaled breath, the measurement of nitrites and nitrates NO degradation products in plasma, and the measurement of flow-mediated dilation FMD in arteries.
However, the usefulness of these measures of in situ responses to stress and the RR is limited by the fact that NOx levels in blood are influenced by several extraneous factors such as dietary nitrate intake and nitrate inhalation from polluted air.
Through these processes, NO is thought to play an integral role in the development of atherosclerotic plaque. In terms of the immune system, NO has the capacity to influence the phenotype of inflammatory cells and thus is capable of influencing the character of immune responses.
Different isoforms of NOS have been identified including some that are constitutively expressed and others whose activation is associated with disease processes. For example, Lind and colleagues have shown that having healthy volunteers engage in 5 minutes of mental arithmetic impaired FMD in the brachial artery.
In Lind's study, the effects of stress on FMD were examined only once at the end of a 5-minute period of mental stress.
