Since ancient times humans have felt intuitively that emotions and health are linked, and recently there has been much popular speculation about this notion. But until now, without compelling evidence, it has been impossible to say for sure that such a connection really exists and especially how it works. Now, that evidence has been discovered. In this beautifully written book, Dr. Esther Sternberg, whose discoveries were pivotal in helping to solve this mystery, provides first hand accounts of the breakthrough experiments that revealed the physical mechanisms-the nerves, cells, and hormones-used by the brain and immune system to communicate with each other. She describes just how stress can make us more susceptible to all types of illnesses, and how the immune system can alter our moods. Finally, she explains how our understanding of these connections in scientific terms is helping to answer such crucial questions as "Does stress make you sick?" "Is a positive outlook the key to better health?" and "How do our personal relationships, work, and other aspects of our lives affect our health?" A fascinating portrait of this rapidly emerging field with enormous potential for finding new ways to treat disease and cope with stress, The Balance Within is essential for anyone interested in making their body and mind whole again.
