Interestingly, Huberman illustrates that short-term stress—when mediated through adrenaline release—can be beneficial for immune activity. The same stress response that elevates alertness and arousal can activate immune pathways. This links directly to the brain’s motivation system; fostering a positive outlook and hope can activate the dopaminergic reward pathways, which have been shown to accelerate healing and reduce inflammation. Laboratory research indicates that thinking positively about the future stimulates these pathways, potentially improving immune resilience.
