Dopamine

What is dopamine?

 Dopamine is a type of monoamine neurotransmitter. It’s made in your brain and acts as a chemical messenger, communicating messages between nerve cells in your brain and your brain and the rest of your body.

Dopamine also acts as a hormone. Dopamine, epinephrine and norepinephrine are the main catecholamines (a label based on having part of the same molecular structure). These hormones are made by your adrenal gland, a small hat-shaped gland located on top of each of your kidneys. Dopamine is also a neurohormone released by the hypothalamus in your brain.

What’s the role of dopamine in my body?

Dopamine plays a significant role in various physiological functions in the body. As a neurotransmitter, it acts as a chemical messenger in the brain and is involved in several essential processes. Here are some key roles of dopamine in the body:

1. Mood Regulation: Dopamine is involved in regulating mood and emotional responses. It is associated with feelings of pleasure and reward, which can positively influence mood and motivation.

2. Reward and Pleasure: One of the primary roles of dopamine is in the brain's reward system. When you engage in activities that bring pleasure or reward, such as eating delicious food or engaging in enjoyable activities, dopamine is released, reinforcing these behaviors and encouraging you to repeat them.
