Your every thought produces a biochemical reaction in the brain. The brain then releases chemical signals that are transmitted to the body, where they act as the messengers of the thought. The thoughts that produce the chemicals in the brain allow your body to feel exactly the way you were just thinking. So every thought produces a chemical that is matched by a feeling in your body. Essentially, when you think happy, inspiring, or positive thoughts, your brain manufactures chemicals that make you feel joyful, inspired, or uplifted.
