What is serotonin?

Serotonin is like a happy helper that helps you feel calm and relaxed.

Imagine your brain is like a busy playground full of kids running around. Sometimes they get too excited and start shouting or fighting, this can make you feel upset or stressed. That's when serotonin comes in, like a friendly teacher who calms everyone down so the playground becomes peaceful again.

Think of serotonin as a special kind of message that travels between your brain cells. When you're happy, relaxed, or sleeping well, more of these messages are sent out. It's like having extra helpers on the playground to keep everything in order.

If there aren't enough of these helpers, maybe because you're tired, upset, or not sleeping well, it can feel harder to stay calm or happy. That’s why people sometimes need more help from serotonin to feel better.

Serotonin is also connected to your sleep and digestion, so it's like a helper that works in different parts of your body too!
