Can your outlook on life actually affect how long you live?
According to a major study published in the Proceedings of the National Academy of Sciences, the answer may be yes.
Researchers analyzing two large epidemiological studies discovered that people who scored highest in optimism had significantly greater chances of living to age 85 or older. In fact, optimists lived 11–15% longer on average than their more pessimistic counterparts.
What Is Optimism?
Psychologists define optimism as a general expectation that good things will happen in the future.
Importantly, optimism does not mean ignoring problems. Instead, optimists tend to believe that setbacks are temporary and manageable.
Why Optimists May Live Longer
Researchers believe optimism supports longevity through several mechanisms:
• healthier lifestyle choices• lower stress levels• stronger social relationships• better cardiovascular health.
Optimists are also more likely to seek solutions when challenges arise, which may reduce long-term stress.
Can Optimism Be Learned?
Yes. Studies suggest mindset can be shaped through habits such as gratitude, reframing negative events, and focusing on achievable progress.
The Bottom Line
If optimism increases both health and longevity, it may be one of the simplest lifestyle changes available.
