Prosocial behavior-voluntary actions intended to benefit others-not only holds moral and social value but also promotes psychological and physical wellbeing through complex neural mechanisms. This Mini Review summarizes current evidence on the health benefits of helping others, including reductions in depression, anxiety, and loneliness, as well as enhancements in positive affect, life satisfaction, and physiological health markers. Then, we provide an overview of the neural systems that support prosociality, highlighting key regions involved in reward processing, empathy, and mentalizing, and how their integration supports flexible, context-sensitive helping behavior. Furthermore, we discuss possible neural pathways linking prosocial actions to stress buffering, mood enhancement, and social connectedness, forming self-reinforcing cycles that sustain wellbeing. We also discuss individual difference factors-including personality traits and early life experiences-that may act to modulate these neural mechanisms and impact prosocial engagement. Understanding how helping others benefits the helper holds promise for advancing population health and fostering resilience across diverse contexts.
