Optimism, Purpose and Longevity: What Two Large Studies Found

The most optimistic women lived about 15% longer than the least optimistic, and adults over 50 with the weakest sense of purpose were more than twice as likely to die during follow-up.

In a 2019 study of two US cohorts, women in the highest optimism quartile had a 14.9% longer life span than those in the lowest, with similar findings in men. In a separate study of 6,985 US adults over 50, those with the lowest life-purpose scores had 2.43 times the risk of death of those with the highest.

Research on longevity has mostly examined physical factors. Two studies published in 2019 looked at outlook: how people expect the future to go, and whether they feel their life has direction.

Optimism

Researchers used two cohorts: women from the Nurses' Health Study, followed for 10 years, and men from the Veterans Affairs Normative Aging Study, followed for 30 years. Optimism was measured with standard questionnaires at the start.

  • Higher optimism was associated with longer life in both sexes, in a graded fashion
  • Women in the highest optimism quartile had a 14.9% longer life span than those in the lowest, after adjusting for demographics and health conditions. Findings in men were similar
  • The most optimistic had 1.5 times (women) and 1.7 times (men) the odds of living to age 85
  • The association with reaching 85 remained after adjusting for health behaviors

Purpose in life

A second study used the Health and Retirement Study, a national sample of US adults over 50. Among 6,985 participants, average age 68.6, those in the lowest category of life purpose had 2.43 times the risk of death from any cause compared with those in the highest. The association was also seen for deaths from heart, circulatory and blood conditions.

Keep it in proportion
Both studies are observational. Poor health can lower optimism and purpose, so part of the link may run in that direction. The researchers adjusted for existing conditions, but adjustment is never complete.

Can outlook be changed?

The optimism study's authors noted that optimism is modifiable. Approaches studied in trials include:

  • Writing down three good things at the end of each day
  • Imagining your best possible future self and writing about it
  • Cognitive behavioral therapy, which trains more balanced thinking

Purpose tends to come from commitments: caring for someone, volunteering, mentoring, or a project that matters to you.

Relationships are part of the same picture. See social connection and longevity.

When to talk with a clinician

Persistent low mood, hopelessness or loss of interest lasting more than two weeks should be raised with a licensed clinician. If you are in crisis in the US, call or text 988.
