Lovely explanation about DOPAMINE!
🎵 🪩 👣 🪘 🗣️
Your brain is made up of billions of nerve cells called neurons. These neurons communicate with each other by sending chemical signals across tiny gaps called synapses.
You can think of synapses like tiny bridges that messages have to cross to get from one brain cell to another.
Dopamine is one of several chemical messengers (neurotransmitters) that crosses these bridges. Your brain uses many different neurotransmitters - including serotonin, norepinephrine, GABA, and glutamate - each with different jobs.
Dopamine plays a particularly important role in motivation, focus, reward, and motor control.
When dopamine levels are low, communication in certain brain pathways doesn't work as efficiently. Messages get delayed or don't get through clearly. This affects everything from motivation to focus to emotional regulation.
So what increases dopamine in the brain?
Exercise is one of the most well-researched ways to boost dopamine. When you move your body, your brain produces more dopamine. This means more chemical messengers are available to cross those synaptic bridges. The increased dopamine improves how well those specific synapses function - messages travel faster and more reliably in those circuits.
Music and rhythm also trigger dopamine release, especially music that your child enjoys or finds pleasurable. Research shows that even anticipating favorite music can start increasing dopamine levels.
Novel experiences - trying something new, exploring unfamiliar environments, or engaging with new activities - activate dopamine systems. This is why switching up routines or introducing new sensory experiences can help some kids engage and focus better.
Social connection increases dopamine too. Positive social interactions, play with peers, and meaningful connection with adults all support dopamine activity in the brain.
ADHD medications work directly on dopamine systems, which is why they can be effective for many kids with ADHD.
Here's what this means for YOUR child:
When dopamine levels are higher, the brain circuits that rely on dopamine work better. Information retrieval becomes easier.
Your child's ability to access what they already know, think more clearly, and process information all work better.
This is why movement breaks aren't just "letting kids burn off energy" - they're actually putting the brain in a better state for learning and functioning. When you see your child fidgeting, seeking movement, or getting restless, their nervous system is often telling them they NEED more dopamine to function well.
That "difficult behavior" you're seeing? It might be your child's brain trying to regulate itself.
So yes - let them move before that math worksheet. Put on their favorite music while they work! Switch up the activity when they're stuck. Let them take breaks to play with a friend.
These aren't rewards for good behavior or breaks from learning. They're literally supporting their brain chemistry to make learning possible.
The brain works better when dopamine is flowing!
And now you know why.
