When you experience joy, you feel good because your magnificent brain produces hormones called endorphins. These self-produced chemicals give you happy and joyful feelings.
Research on these biochemicals has proven that the brain-produced hormones enter your blood stream even if you just act joyful, not only when you really are happy. Although the joyful experience is totally imaginary and you know that it didn’t actually happen, when you speak and act as if that imaginary experience did happen, you get a dose of endorphins.
These chemicals are naturally produced by your brain. They are totally free and entirely healthy.
Many people find that this knowledge inspires them to create more joyful moments. It’s not just an abstract idea, but a physical reality.
