womanthismonth.com | APRIL 2025 44 OPINION Dopamine Diaries: Your Brain’s Happy Chemical Board-Certified Behaviour Analyst, Fifi Kiwan, discusses dopamine, the brain’s most celebrated ‘feel-good’ chemical, and how it affects us and what we can do to keep our levels in check. What Is Dopamine? Dopamine is a neurotransmitter, a fancy term for a chemical messenger that helps transmit signals in the brain. Think of it as a little courier, delivering messages between neurons (brain cells) to help regulate various functions in your body. It plays a crucial role in mood, motivation, reward and even movement. When you accomplish something, like finishing that Netflix series you’ve been binging or successfully cooking a new dish, your brain releases dopamine. This momentary rush of joy is your brain’s way of saying: “Well done! Let’s do that again!” The Bright Side of Dopamine Dopamine is like the cheerleader of your brain. Here’s how it positively impacts your life: 1. Motivation & Reward: Dopamine drives you to pursue goals. It’s that little voice that whispers ‘You can do it!’ when you’re tackling a project or trying to hit the gym. The more you achieve, the more dopamine you get, creating a satisfying cycle of motivation. 2. Mood Regulation: A healthy level of dopamine contributes to a positive mood. When you feel happy and content, it’s often thanks to this little chemical helping you out. 3. Learning & Memory: Dopamine is essential for learning. It helps reinforce behaviours that lead to positive outcomes, making you more likely to repeat those actions.
