Tina Woods, Founder and CEO of Collider Health, explains why the positive psychosocial exposome is core to the next frontier of longevity.
The longevity industry has spent the past decade building increasingly sophisticated tools to understand human biology.
Today we can estimate biological age from blood tests, analyze organ-specific aging trajectories, continuously monitor sleep, glucose and cardiovascular health, and increasingly personalize interventions to individual physiology.
Yet despite extraordinary advances in biomarkers, diagnostics and therapeutics, a fundamental challenge remains. Most of the factors that determine how long and how well we live are not found in our biology alone.
They are found in our exposures. Where we live. How we connect. Whether we feel safe, valued and purposeful. The quality of our relationships. The communities we belong to. The environments we move through every day.
These factors form part of what scientists call the ‘exposome’: the totality of environmental, behavioural, social and psychological exposures that shape human health across the lifespan.
Historically, exposome science has focused primarily on harmful exposures – pollution, smoking, poor diet, chronic stress, loneliness and social isolation.
But what if we have been overlooking the other side of the equation?
What if positive exposures matter too?
What if joy, belonging, purpose, social connection and collective experiences are not simply lifestyle preferences but biologically meaningful determinants of healthspan?
This question sits at the heart of a new concept we are developing in the JoyScore Experiment: the Positive Psychosocial Exposome.
The Positive Psychosocial Exposome describes the cumulative set of beneficial social, emotional, behavioural and experiential exposures that contribute to resilience, flourishing and healthy longevity.
Just as sleep, nutrition and physical activity influence biological aging, positive psychosocial experiences may also influence aging through inflammatory, autonomic, neuroendocrine and behavioural pathways.
The challenge has always been measurement, and until recently, many of these experiences were considered too subjective to quantify meaningfully.
But this is beginning to change. Recent research demonstrated that something as seemingly simple as sleep duration can be linked to biological aging clocks, proteomic signatures and mortality risk. If sleep can be quantified as a biologically meaningful exposure, perhaps joy, connection and belonging can too.
This idea underpins the JoyScore Experiment to investigate whether higher levels of positive psychosocial exposure are associated with slower biological aging and improved healthspan and resilience.
Rather than simply asking people how they feel, the JoyScore Experiment combines ecological momentary assessment, wearable neurotechnology, heart-rate variability, metabolomics, glycomics and epigenetic markers to investigate how positive experiences impact our internal biology over time.
The framework distinguishes exposures, mediators and outcomes, and tests the hypothesis that synchrony across behavioural, cardiac and neural systems represent a measurable pathway through which social connection influences resilience and wellbeing.
In other words, when people move together, regulate emotions together and share meaningful experiences, measurable biological processes may be occurring beneath the surface.
We have already begun exploring this hypothesis. Following an initial feasibility pilot in San Francisco, the first longitudinal cohort was conducted in Roatán, Honduras earlier this year.
The findings remain preliminary and exploratory, but they provided an important signal.
Among participants actively engaging in the JoyScore Group of the Longevity Biomarkers Competition only 55% showed worsening in PhenoAge compared with 88% among those who were not actively participating. The sample size was small and no definitive conclusions can yet be drawn, but the findings were sufficiently encouraging to support further investigation and were presented at the Global Exposome Summit earlier this year.
Perhaps the most interesting implication is not scientific but strategic. If positive psychosocial exposures can be measured, they can also be designed, valued and evaluated. This changes how we need to think about longevity.
Much of today’s longevity industry remains focused on highly personalized, high-touch interventions delivered through specialist services that are often beyond the reach of most people. While these approaches are valuable, but they are difficult to scale to populations.
As I prepare to speak at the London Longevity Show on scaling longevity health networks, I believe one of the industry’s biggest opportunities lies in creating systems that improve the exposures people experience every day.
This means moving beyond self-optimisation and towards a more collective view of longevity.
It means asking how cities can reduce loneliness. How workplaces can increase belonging and purpose. How hospitality can support wellbeing. How communities can contribute to resilience. How music, culture and collective experiences can foster connection. And ultimately how positive psychosocial exposures can become part of preventive health strategy and infrastructure.
This thinking is reflected in one of the most visible use cases of the JoyScore Experiment: Longevity Rave which is running on the morning of the 27th June at Longevity Show.
While unconventional, Longevity Rave that I co-founded with Yukari Takhisa, is not simply an event, it is a living laboratory for the social exposome. It allows us to explore how music, movement, belonging and intergenerational connection influence health and wellbeing in real-world environments.
The longevity movement has already transformed how we think about aging biology. The next challenge is understanding the environments that shape that biology.
The future of longevity will not be built solely through better diagnostics, drugs and biomarkers. It will also depend on our ability to measure, design and scale the conditions that allow people to flourish, in the communities, cultures and collective experiences that make life worth living.
Hear Tina Woods speak – and join the Longevity Rave – at The Longevity Show. Taking place at Tobacco Dock, London, on 26–27 June 2026, the Show brings together leading voices from longevity science, preventive healthcare, wellness, technology and investment. Tickets for all tiers are now available at www.longevityshow.com.
