Your emotions tell you something about your autonomic nervous system which is connected to your other systems in your body, including the immune, endocrine-, digestive- , and cardiovascular system, just to name a few. It is called psychoneuroimmunology. If you feel at peace, your body is relaxed, and in a place of safety. Your nervous system signals your body – no danger, all is good. This state is where all your other systems work in balance and harmony, helping your body to eliminate pathogens, detoxify, digest, transport oxygen and nutrients, and lots more.
