Chronic stress contributes to roughly one in five deaths in the US every year. High stress levels reduce life expectancy by nearly three years, while perceived stress raises mortality risk by 43 percent over two decades.
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
- High stress cortisol impairs vaccine response by 30-50%
- Bereaved individuals have 2x pneumonia death risk first month
- Chronic depression from stress increases stroke risk by 45%
