Stress assessment methods

There is no single clinically validated blood test or device that can accurately quantify overall stress. The most reliable approach combines validated questionnaires with simple physiologic and health metrics. • Validated questionnaires: Perceived Stress Scale (PSS‑10) is the standard for perceived stress; GAD‑7 assesses anxiety and PHQ‑9 assesses low mood, both of which often co‑occur with chronic stress. Sleep quality screens (e.g., PSQI) are also useful. • Physiologic markers (useful for trends, not diagnosis): Heart rate variability (HRV) from wearables reflects autonomic balance but varies with fitness, sleep, illness, alcohol, and medications. Cortisol measured in blood, saliva, or hair shows wide diurnal and day‑to‑day variation and is not reliable for routine stress testing unless evaluating specific endocrine disorders. Catecholamines, C‑reactive protein (CRP), and glucose can change with stress but are nonspecific and influenced by many factors. • Downstream health impacts to monitor: blood pressure, glucose/HbA1c, lipids, weight/waist circumference, sleep duration and quality, and stress‑related symptoms such as headaches, gastrointestinal upset, muscle tension, or irritability. Practical strategy: complete a brief stress scale (e.g., PSS‑10) periodically, track sleep and HRV trends with a wearable, record home blood pressure and any symptoms, and address identified stressors (e.g., workload, recovery gaps) with consistent sleep, regular aerobic activity, mindfulness or breathing exercises. Re‑assess questionnaires and metrics after several weeks to gauge improvement.
