A positive attitude enhances immune system functioning through specific neuroendocrine mechanisms
Psychoneuroimmunology and clinical research demonstrate that psychological states and mind-body interventions significantly influence immune function via neuroendocrine pathways such as the hypothalamic-pituitary-adrenal axis.
The retrieved papers provide robust evidence from meta-analyses, systematic reviews, and psychoneuroimmunology studies indicating that emotional states, psychological well-being, and mind-body interventions modulate immune function through specific neuroendocrine mechanisms, such as HPA axis regulation and stress hormone signaling.

This meta-analysis demonstrates that mind-body interventions positively alter neuroendocrine and immune parameters, reducing inflammatory factors and enhancing immune-activating molecules.
