Not Medical Advice
Always consult a qualified healthcare professional before making significant changes to your health behaviors, exercise routine, sleep habits, or diet, especially if you have a pre-existing medical condition, are pregnant, or take prescription medications.
Scientific Uncertainty
The ZNTNT behavioral aging engine is informed by peer-reviewed longevity research, including Shim, Fleisch & Barata (2024) published in npj Digital Medicine. Our scoring methodology draws on published circadian biology, metabolic health, and resilience research.
Known scientific uncertainties in our current model include:
- Bedtime standard deviation as a proxy for circadian disruption (validated in population studies but not at individual level for a 90-day window)
- Eating window duration as a proxy for metabolic aging trajectory (correlated in observational data but causality not established)
- Whether our longitudinal individual tracking approach is directly comparable to population-relative constructs used in the academic literature
Zentient is honest about these limitations because we believe scientific transparency builds more trust than overclaiming. Our beta program is designed to generate longitudinal data that will allow us to answer these questions rigorously. The ZNTNT engine has not been independently validated as a clinical instrument and should not be used as one.
Orthosomnia / Metric Anxiety Warning
A note on tracking anxiety: Research suggests that some people experience increased sleep anxiety when tracking sleep metrics, a phenomenon sometimes called 'orthosomnia.' Your Longevity Score is designed to help you build better long-term habits, not to create stress about individual nights or single data points. If you notice the app increasing your anxiety rather than reducing it, we encourage you to adjust your tracking settings or consult a healthcare professional.
