Exercise enhances mood through a muscle-derived protein called apelin that travels to the brain and supports neurogenesis and neural signaling, linking physical activity with improved depressive-like behaviors in animal models. The findings identify a specific molecular pathway by which exercise may influence brain function and mood.

This topic is of interest to psychology because it connects physical activity, brain chemistry, and emotional well-being, highlighting mechanisms behind mood regulation and the potential for non-pharmacological influences on mental health.
