Purpose in Life: The Overlooked Factor in Healthy Ageing
What if one of the most powerful interventions for lifespan and healthspan isn't found in a prescription pad — but in helping people explore meaning and purpose in their lives?
Recent long-term studies indicate that a sense of purpose may be just as clinically significant as optimising exercise and managing chronic conditions. For those navigating the transitions of midlife and beyond — retirement, bereavement, unexpected health events, chronic illness, or caregiving — there is growing evidence that purpose matters and is associated with reduced risk of chronic diseases and mortality.
The Mortality and Healthspan Evidence
A study from 2022 published in the American Journal of Health Promotion tracked nearly 13,000 inidviduals across the United States aged over 50 (Kim et al., 2022). Those with the highest sense of purpose had a 46% reduced risk of all-cause mortality — even after controlling for physical health, depression, loneliness, personality traits, and socioeconomic status.
The same study found that higher purpose was also associated with reduced risk of stroke, lung disease, and physical limitations with everyday activities (Kim et al., 2022). Purpose, it seems, isn't just about feeling fulfilled; it's protective at a biological level.
When it comes to healthspan — the quality of our years as we age — research using the Health and Retirement Study tracked almost 14,000 individuals aged over 50 across eight years, exploring five key health behaviours (Kim et al., 2020). Among those who were initially engaging in a healthy lifestyle, those with the highest sense of purpose were less likely to become physically inactive, develop sleep problems, or develop an unhealthy BMI.
Those associations were also maintained after adjusting for baseline health status and depression — indicating that purpose operates as an independent protective factor, not just a proxy for good health or positive mood (Kim et al., 2020).
Purpose and the Brain: A Key Window in Midlife
Perhaps the evidence that stands out the most, is what purpose does for cognitive health. A 2025 study in The American Journal of Geriatric Psychiatry followed over 13,000 adults aged 45 and older for up to 15 years (Howard et al., 2025). Those with higher levels of purpose showed around 28% lower risk of developing cognitive impairment; and this protective effect remained significant even after accounting for education, depression, and the APOE4 gene, a known risk factor for Alzheimer's disease.
Research with older adults aged 68 to 96, found that higher purpose was associated with cognitive decline occurring around 1.4 months later over an eight-year period (Sutin et al., 2024). While that might sound modest, it's comparable to delays achieved by currently available medications, without the side effects.
A 28-year longitudinal study found that purpose assessed at age 52 predicted better global cognitive function and verbal fluency at age 80 (Sutin et al., 2025). This suggests that midlife — often a period marked by significant transitions such as children leaving home, ageing parents requiring care, or career shifts — may be a key window for cultivating purpose with cognitive benefits that last decades.
Why does purpose protect cognition? A 2024 study found that a stronger sense of purpose independently predicted more frequent engagement in cognitively stimulating activities — such as reading, puzzles, and social group activities — even after adjusting for age, income, and retirement status (Lewis et al., 2024). Purpose, in other words, drives the behaviours that build cognitive reserve.
Importantly, the relationship between cognitive decline and purpose is bidirectional (Boyle et al., 2010; Howard et al., 2025). The onset of cognitive impairment is associated with declining purpose, but declining purpose may also accelerate cognitive decline. This creates a cycle that, if recognised early, can potentially be a target for psychological intervention aimed at improving health and wellbeing (Kim et al., 2022).
Psychological Protection: Anxiety, Depression, and Coping
Purpose also confers substantial psychological protection. Kim et al. (2022) found that those with the highest versus lowest sense of purpose had a 43% reduced risk of depression, alongside greater psychological wellbeing including life satisfaction, optimism, sense of mastery, and less loneliness.
A study from 2023, with over 1,600 individuals aged 18 to 99 years, found that sense of purpose was negatively associated with anxiety symptoms (Pfund et al., 2023). Those with higher purpose were more likely to use adaptive coping strategies when anxious, such as finding the “silver lining” or the unexpected upside, and focusing on the “big picture” (Pfund et al., 2023).
Higher purpose also reduced unhelpful coping strategies. Older adults with higher purpose were least likely to bottle up their negative emotions or rely on comfort eating, alocohol or other forms of avoidance (Pfund et al., 2023). This indicates that purpose supports more adaptive emotional regulation across the lifespan; particularly in later life.
The Mechanisms: Why Purpose Works
The research points to four key pathways through which purpose protects health and wellbeing:
First, behavioural alignment. Individuals living with purpose consistently prioritise health-maintaining behaviours, such as regular physical activity, preventive health check-ups, adequate sleep, and stronger social connections (Kim et al., 2020, 2022). Research also shows purposeful individuals find it easier to make healthy choices (such as taking the stairs or the escalator) and are more receptive to health advice (Kim et al., 2020).
Second, stress regulation. Purpose reframes adversity, helping people recover from life's challenges (Kim et al., 2022). People with higher purpose perceive stressors as less threatening, and display greater self-efficacy, and less impulsivity (Kim et al., 2020). It may be that this disrupts the pathway between stress and unhealthy behaviours, including a sedentary lifestyle, poor sleep, and comfort eating.
Third, biological benefits. Studies indicate that people with a strong sense of purpose show less inflammation and lower allostatic load (or wear and tear on the body and brain due to chronic or repeated stress as we age) (Kim et al., 2022). These biological pathways may help explain why purpose's benefits extend to hard clinical endpoints like stroke, lung disease, and mortality (Kim et al., 2022).
Fourth, emotional regulation. People with a strong sense of purpose tend to handle and reframe stress differently. Instead of pushing feelings away, they try to make sense of what’s happening and keep perspective (Kim et al., 2020; Pfund et al., 2023). Over time, this protects the body from the kind of chronic stress that contributes to ageing and illness (Kim et al., 2022).
What This Means for You
When you experience challenging life transitions — retirement, bereavement, unexpected health events, or the uncertainties of aging — existential distress isn't just emotional. The evidence indicates it may be a modifiable risk factor for both lifespan and healthspan (Kim et al., 2020, 2022).
Purpose isn’t reserved for extraordinary achievements. In a study of 40 South Australians aged 68–96, researchers found that purpose showed up in four everyday domains of life (Irving, 2025):
• Meaningful relationships — caring for family and pets, mentoring others, contributing wisdom
• Contribution — volunteering, advocacy, campaigning, and ongoing meaningful work
• Learning and growth — pursuing hobbies, staying curious, developing new skills through which they could gain a sense of mastery
• Values alignment — spiritual practices, acts of kindness, causes that matter to you
And here's the hopeful part: purpose can be cultivated. Emerging randomised controlled trials — ranging from volunteering programmes to cognitive behavioural therapy groups — indicate that sense of purpose can be enhanced (Kim et al., 2022). A recent trial with adults over 60 years of age, found that structured training in humour, forgiveness, savoring, and meaning-making, were all equally effective at reducing anxiety and depression while increasing wellbeing, with benefits maintained three months after intervention (Salces-Cubero et al., 2025).
Older adults who actively value and pursue purpose in everyday life — creating reasons to ”get up and get on” — tend to live with visible zest (Irving, 2025). They tend to maintain meaningful roles, contribute to others and the “greater good”, have routines of their choosing, sustain independence, and often describe faith, spirituality, or a sense of calling as central to their lives (Irving, 2025).
