What is the Meaning of Stress Response?

The stress response is the body's integrated physiological and behavioral reaction to any perceived or actual threat to homeostasis, orchestrated primarily by the neuroendocrine system. This adaptive mechanism involves the rapid activation of the Sympathetic Nervous System and the slower, sustained activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis, leading to the release of catecholamines and glucocorticoids like cortisol. While acutely beneficial for survival, chronic or dysregulated stress responses contribute to systemic inflammation, hormonal imbalance, and accelerated aging, making its management a key clinical priority.

What is the Origin of Stress Response?

The concept was formalized by Hans Selye in the mid-20th century as the General Adaptation Syndrome, describing the body's non-specific response to stressors. The term "stress response" has evolved to encompass the detailed neuroendocrine pathways involved in this adaptation. Its clinical significance lies in recognizing the profound, systemic consequences of chronic activation on metabolism, immunity, and mental health.

What is the Mechanism of Stress Response?

The response begins in the brain, where the hypothalamus releases CRH, initiating the HPA axis cascade that culminates in cortisol release from the adrenal cortex. Simultaneously, the sympathetic nervous system releases norepinephrine and epinephrine (adrenaline) for immediate effects on heart rate and blood pressure. The acute mechanism diverts energy from non-essential functions, but chronic activation leads to persistent high cortisol, which can desensitize receptors, impair immune function, and disrupt the delicate balance of other hormones like testosterone and estrogen.
