What is the Origin of Physiological Stress Biomarkers?

The concept emerged from the integration of clinical endocrinology, immunology, and laboratory medicine, seeking objective measures to validate the subjective experience of stress. The development of sensitive assays for hormones and inflammatory mediators allowed for the transition from purely psychological assessments to measurable physiological states. The term emphasizes the biological, rather than purely psychological, impact of stress.

What is the Mechanism of Physiological Stress Biomarkers?

When the body encounters a stressor, the Hypothalamic-Pituitary-Adrenal (HPA) axis and the Sympathetic Nervous System (SNS) are activated, leading to the release of hormones like cortisol and adrenaline. The biomarkers measure the downstream effects of this activation; for instance, cortisol levels reflect HPA axis activity, while elevated C-reactive protein indicates systemic inflammation driven by chronic stress. Monitoring these changes allows for precise clinical intervention to restore homeostatic balance.

Physiological Stress Biomarkers

Meaning

Physiological Stress Biomarkers are quantifiable biochemical, hormonal, or cellular indicators measured in biological fluids or tissues that objectively reflect the magnitude and chronicity of the body’s systemic stress response. These markers, which include cortisol, DHEA, C-reactive protein, and heart rate variability, provide a clinical snapshot of the allostatic load placed on the endocrine and immune systems. They are essential tools for personalized stress management.
