Key Takeaways
- Chronic stress accounts for 15-20% of all US deaths annually
- High stress shortens life expectancy by 2.8 years, meta-analysis
- Perceived stress predicts 43% higher mortality risk over 20 years
- Chronic stress increases breast cancer recurrence via immune escape 2x
- Job stress raises breast cancer risk 32% in women
- Depression stress linked to 39% higher lung cancer mortality
- Chronic stress increases the risk of coronary heart disease by 27% according to a meta-analysis of 5 cohort studies
- Job strain (high demand, low control) is associated with a 1.47 relative risk of cardiovascular mortality
- People with high stress levels have a 43% increased risk of recurrent coronary events post-heart attack
- Chronic stress suppresses immune function, doubling cold susceptibility

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
