serotonin

They all interact with the body's serotonin neurotransmitter system, which regulates many processes, including mood, sleep-wake cycles, appetite, and memory.

People openly talk about the idea we're increasing serotonin, we're correcting our chemical imbalance.

It doesn't increase serotonin like SSRIs.

Every single time you move your body, you are giving your brain what I like to call a wonderful bubble bath of neurochemicals: dopamine, and serotonin, and noradrenaline, and endorphins.
