When you feel happy, your body will produce ‘happy’ neuropeptide equivalents such as joy has a joy neuropeptide. Feel angry, it will produce ‘angry’ neuropeptide equivalents. Your psychology, via neuropeptides, literally becomes your biology.
Once neuropeptides are produced, these messenger substances flood the body with information. This information influences the way your body works! Your body then feeds back to the mind, affecting how you feel and even what you think.
Neuropeptides are produced in response to emotions, but also to food, the way we breathe, and even how we move and hold our bodies. Any disease process or physical body imbalance will interfere with the production and flow of neuropeptides (emotions) around the body.
