Psychoneuroimmunology

Meaning

Psychoneuroimmunology (PNI) is the sophisticated, interdisciplinary field of study that systematically examines the complex, bidirectional interactions between psychological processes, the nervous system, the endocrine system, and the immune system. This discipline provides the essential scientific foundation for understanding how chronic psychological stress, emotional states, and specific behavioral factors can directly influence systemic physiological health, including immune function, inflammatory status, and hormonal balance. PNI emphasizes the constant, intricate communication between the brain and the body’s defense mechanisms, offering crucial, actionable insights into stress-related pathologies and the design of effective wellness interventions.
