Those who work in the field of healthcare have known for some time that a connection exists between our underlying beliefs and thoughts and the functioning of our bodies. Dr. Herbert Benson, in his 1970's landmark book, The Relaxation Response, articulated the concept that stressors can trigger a "fight or flight response", an inner startle response that indicates we are about to experience an unpleasant event. Although there is a healthy fear that protects us from harms way, many times how one interprets stressful events and one's ability to manage it, can affect the immune systems functional capacity. There is now sufficient research to validate Benson's work, that relaxation techniques such a meditation, can have a direct link to minimizing the effect of a wide range of disorders such as high blood pressure, irritable bowel syndrome, back problems, neurological pain, and headache problems. Relaxation strategies calm the sympathetic nervous system, making it easier for the body to heal.
In Barbara Levine's book, Your Body Believes Every Word You Say, she explores how our thoughts and underlying beliefs about our physical maladies affect our auto-immune system which regulates our ability to ward off illness, manage pain, and promote healing. In other words, legitimate pain from various illnesses and somatic complaints can be intensified by the kind of messages we tell ourselves. Spontaneous self-defeating thoughts such as, "What's the use, my body will always betray me and never get better." can reinforce the pain cycle of making things worse. People with such chronic self-defeating reactions have been shown to create inner chemical changes and constricted blood flow which further erodes the individual's ability to manage pain. How we respond to our bodily disorders, in terms of core beliefs and inner dialogue, may affect the outcome of our health.
