Emotions have a direct effect on how our bodies work. Fear-based emotions stimulate the release of one set of chemicals while love-based emotions release a different set of chemicals. If the fear-based emotions are long-term or chronic they damage the chemical systems, the immune system, the endocrine system and every other system in your body. Our immune systems weaken and many serious illnesses set in. This relationship between emotions, thinking, and the body is being called Mind/Body Medicine today.
