Stress Response Physiology

Meaning

Stress Response Physiology is the integrated scientific study of the body’s rapid and sustained adaptive biological and hormonal changes, which are primarily mediated by the Hypothalamic-Pituitary-Adrenal (HPA) axis and the sympathetic nervous system, in reaction to any perceived or actual stressor. This coordinated physiological response involves the rapid release of catecholamines followed by the slower, sustained secretion of cortisol, fundamentally altering metabolism, immune function, and cardiovascular output. Understanding the intricate dynamics of stress response physiology is absolutely critical for effectively managing chronic stress-related endocrine disorders.
