Because of these effects, many of us refer to dopamine as the ‘feel-good chemical,’ since it’s connected with pleasure and rewards.

Today, in this blog, we will discuss dopamine function, its role in the brain and body, how it affects mental health, and the effects of being too high or too low.

Role of Dopamine in the Body?

What is Dopamine? Dopamine is a monoamine neurotransmitter made by your brain. It works as a chemical messenger, carrying signals between nerve cells in your brain and the rest of your body.

Our brain releases dopamine when we feel something very exciting and satisfying. Here are some examples are
