Illustrative pathway
Chronic stress → Raised blood pressure → Stroke
Relationship
Contested: Evidence conflicts; treat as a hypothesis.
Evidence and uncertainty
Cohort studies; high uncertainty.
Summary
Stress produces short blood pressure rises; whether chronic stress causes lasting hypertension and stroke independent of behaviour is contested.
Limitations
Stress clusters with smoking, alcohol, diet and poverty; separating psychological effects from behaviours is difficult.
