Stress Management
This domain tests whether you can treat chronic stress as a measurable clinical problem rather than a vague complaint. You should know the physiology, the evidence-based interventions, and how to avoid promising that relaxation cures disease.
Physiology
Acute stress activates the sympathetic-adrenal-medullary axis (catecholamines) and the HPA axis (cortisol). Chronic activation - allostatic load - is associated with hypertension, insulin resistance, central adiposity, inflammation, depression, and adverse health behaviors such as smoking and overeating. The INTERHEART study identified psychosocial stress as a contributing risk factor for myocardial infarction.
What works
- Slow diaphragmatic breathing at about 6 breaths per minute increases vagal tone and heart rate variability.
- Mindfulness-based stress reduction (MBSR), an 8-week program, reduces perceived stress and anxiety symptoms; mindfulness-based interventions have moderate evidence for depression and anxiety.
- Progressive muscle relaxation, guided imagery, yoga, tai chi, and nature exposure have supporting evidence.
- Group programs and apps improve access, but evidence quality varies.
Assessment
Use a validated measure such as the Perceived Stress Scale, and screen for depression (PHQ-9) and anxiety (GAD-7). Ask about stressors - caregiving, work, finances, trauma - because the intervention may be social or practical rather than psychological.
Worked example
A 52-year-old with treated hypertension reports "constant pressure" at work, poor sleep, and a Perceived Stress Scale score of 27. Reasoning: screen for depression and anxiety; recommend 10 minutes daily of slow breathing plus referral to an 8-week MBSR course; keep antihypertensives unchanged and recheck blood pressure; review in 6 weeks. The error is telling her to "relax more" with no skill, dose, or follow-up.
Traps
- Substituting relaxation for indicated pharmacotherapy or psychotherapy.
- Recommending unproven supplements for stress.
- Treating stress as unrelated to the other pillars - it drives sleep, eating, and substance use.
- Assuming stress is always harmful; short-term challenge can improve performance, and the target is chronic unmanaged stress.
