HPA Axis Interplay

Meaning

HPA Axis Interplay describes the dynamic, bidirectional communication and complex regulatory feedback system linking the Hypothalamus, Pituitary gland, and Adrenal glands. This neuroendocrine axis is the central conductor of the body’s physiological response to stress, governing the secretion of glucocorticoids, most notably cortisol. Maintaining optimal HPA axis interplay is vital for preserving metabolic health, immune function, and psychological resilience.
