do sistema imunitário

"There is mounting evidence that this might be possible. A whole new field has emerged in the past ten years, known as psychoneuroimmunology, or PNI, beautifully described for the layperson in the book The Healer Within by Dr. Steven Locke of the harvard Medical School, and Douglas Colligan. Simply put, studies in this new field are showing tht our body's many exquisite cellular and molecular defense mechanisms against infection and disease, known collectively as the immune system, do not operate in a vacuum to keep us healthy. As the term psychoneuroimmunology suggests, the immune system is now known to be regulated in parte at least by the nervous system, which integrates all the organ systems of the body so that we can function harmoniously as a unified organism. And of course, the nervous system makes the life of the mind possible. So there appear to be important interconnections, as yet only poorly understood, between the brain and the immune system. This means that science now has at least a plausible working model to explain how our thoughts and emotions and life experiences might, under some circumstances, influence our susceptibility or resistance to disease."
