Serotonin and dopamine are both brain chemicals (neurotransmitters) that affect mood and behavior, but they do different jobs. Serotonin is more about mood stability, calm, and well-being; dopamine is more about motivation, reward, and the drive to seek things out.

Frequently asked questions
What's the simplest difference between serotonin and dopamine?
Roughly: serotonin is about feeling content and stable ('I have enough'), while dopamine is about wanting and pursuing ('I want that'). Both shape mood, but in different ways.
Which one is the 'happy' chemical?
Both get called that, but it's a simplification. Serotonin leans toward contentment; dopamine toward motivation and reward. Happiness involves many chemicals and circumstances.
Can you boost them naturally?
Exercise, sleep, sunlight, and diet are linked to healthier neurotransmitter function — but for clinical concerns, see a professional. This is general information, not medical advice.
