The Science of Purpose

How purpose powers wellbeing

Living with purpose brings more than just meaning to your life. It’s a lever that can impact virtually every aspect of your psychological, physical, emotional, and behavioral wellbeing. More than 1,400 studies have examined purpose in life, and the results are clear. A strong sense of purpose is associated with a host of wellbeing benefits, many of which may be surprising. But first, let's talk about the science behind why purpose works so well as a powerful wellbeing tool.

NOTE: You'll see footnotes throughout this text for related studies—you can find an ordered listing of those studies at the bottom of this page.

The Neuroscience

What happens in the brains of people with a strong sense of purpose?

Some of the world’s leading neuroscientists have studied the effect of purpose on people’s brains through magnetic resonance imaging^1,2,3 and have found three primary neural responses:

• People with a strong sense of purpose have reduced cognitive conflict. The dorsal anterior cingulate, and area of the brain associated with conflict, is less active in people with a stronger sense of purpose.
• Purpose activates neural regions associated with emotional self-regulation and control of fear and anxiety. The ventromedial prefrontal cortex, which is associated with our sense of self, decision-making, and future orientation, is activated when purposeful values are affirmed in study subjects.
• Activation of the ventromedial prefrontal cortex suppresses activity in the amygdala, the fear center of our brains.

This is your brain on purpose

The following image shows resting-state functional magnetic resonance imaging (rs-fMRI) scans of high purpose (HP) and low purpose (LP) research subjects⁴ — you can see for yourself how much more interregional activity occurs in the HP brain versus the LP brain.

Benefits of strong purpose in life

Our neural responses help explain the many psychological, emotional, physical, behavioral, and even financial benefits we see in people with a strong sense of purpose. Research has found having a strong sense of purpose is linked to a host of benefits, including the following:

• Longer, better lives.⁵ A strong sense of purpose is associated with adding 7 to 7.5 years to a person’s life.
• Better sleep. Researchers have found that a strong sense of purpose supports both a better night’s sleep when measured in isolation,⁶ and better sleep over time.⁷
• Greater resilience to psychological stressors, including negative events⁸ and trauma.^9,10,11
• Lower levels and lower risk of depression and anxiety. People who have a strong sense of purpose are roughly half as likely to be depressed and anxious as those who don’t. Many studies covering thousands of people from different backgrounds, including recent meta analyses covering hundreds of studies and over a half million people,^12,13 have shown this link.
• Greater resilience to physical stressors,¹⁴ including pain. A strong sense of purpose is even associated with higher heat and cold pain thresholds.¹⁵
• Stronger immune systems and lower inflammation.^16,17,18,19 
• Higher cognitive functioning and healthier cognitive aging.^{20,21,22,23,24}
• Better long-term health decisions, including exercising,^25,26,27 using preventive health services,²⁸ better disease management,^29,30 and positive health-related behaviors.^31,32 A higher sense of purpose is associated with increased use of preventive screenings, including mammography, cholesterol tests, and colonoscopies.
• Lower risk of heart disease, stroke, and mortality.^{5,32,33,34,35} A strong purpose is associated with a 22% lower risk of clinical strokes³⁶ and has been linked to faster stroke recovery.³⁷
• Lower risk of dementia and Alzheimer’s disease.^4,20,22,35 People with a strong sense of purpose are 2.4x less likely to develop Alzheimer’s disease. Eight epidemiological studies have found significantly higher rates of dementia and Alzheimer’s disease over time among recent retirees who are unable to “re-purpose” their lives. 
• Faster repair and better protection of chromosomes.³⁸ Researchers have learned that telomeres, which protect the ends of our chromosomes, appear to be stronger in those with a strong sense of purpose.
• Fewer hospitalizations and faster rehabilitation.^28,39
• Reduced epigenetic age. The “biological clock” appears to run more slowly⁴⁰ and allostatic load (wear and tear on the body) is lower⁴¹ in those with high sense of purpose.
• Increases in good cholesterol,^33,42,43 high-density lipoprotein (HDL), which protects cardiovascular health and removes excess low-density lipoprotein (LDL, or “bad” cholesterol) from arteries and tissues. Higher HDL levels are associated with anti-inflammatory and antioxidant effects, and can help prevent blood clots. 
• Better sex.^44,45,46 Multiple studies have demonstrated that people who have a purpose in life tend to have more satisfying sex lives.
• Better and longer lasting outcomes from addiction treatment,⁴⁷ and reduced risk of drug misuse.⁴⁸

Greater income and higher net worth.⁴⁹ A strong sense of purpose is associated with greater financial success, independent of other predictors such as demographics, education level, and personality traits.
