Most health frameworks measure one domain. The clinical reality is that chronic stress compounds across several — and the pattern forms before any single domain looks alarming.
A wearable measures recovery. A meditation app measures mind. A nutrition tracker measures body. The single-domain frame is useful — and incomplete.
The clinical reality is that chronic stress does not stay in one domain. It compounds across several. Sleep deteriorates first, then mood, then movement, then social withdrawal, then a quiet erosion of motivation. By the time any single measurement looks alarming, the pattern has been forming for weeks across the others.
The Alignment Pulse measures six. The choice of six is not arbitrary. Each domain maps to a distinct body of peer-reviewed research with well-validated measurement properties at the daily timescale. Together, the six cover the territory where chronic stress, allostatic load, and burnout actually manifest — before they become a diagnosable condition.
This is the framework.
Mind measures where you are in your head today: how clear, how reactive, how capable of focused attention.
The literature on mind-domain interventions is among the strongest in health-related research. Mindfulness-based therapy, cognitive behavioral therapy, self-compassion training, and brief contemplative practices all show meaningful effects across hundreds of trials. Even short interventions — a single breathwork session, five minutes of expressive writing — produce measurable shifts in stress physiology.
But mind never functions in isolation. The most diagnostic compound patterns — System Overload, Burnout Signature — always involve mind drifting alongside another domain. Measuring mind alone misses the pattern. Measuring mind across days, alongside the other five, surfaces it.
Read the research on Mind →Body measures the somatic baseline: nutrition, inflammation, and interoceptive awareness — the ability to sense internal states like heart rate, hunger, breath, or fatigue.
The evidence connects diet to mental health through inflammatory pathways. Mediterranean dietary patterns have meaningful antidepressant effects. Ultra-processed food intake has been linked to elevated depression risk. Omega-3 supplementation and probiotic interventions show effects on mood. Interoceptive accuracy predicts emotional regulation across multiple studies.
The body domain is where the abstract becomes physical. A pattern that involves body and movement together typically reflects autonomic nervous system tension. A pattern that involves body alone usually points to nutrition or inflammation.
Read the research on Body →Movement measures physical activity, mobility, and the ability to use your body without effort.
Exercise is one of the most effective interventions for mental health, with effect sizes for major depressive disorder approaching the magnitude of medication. Resistance training reduces both anxiety and depression. Even brief movement — a short walk after meals — produces measurable metabolic benefits. The dose-response curve is well-established: a few hours per week of moderate activity reduces depression risk meaningfully.
But movement is also the domain that tends to drop first when other domains drift. A drop in movement is often the early canary for an emerging compound pattern — Burnout Signature in particular.
Read the research on Movement →Recovery measures the system's capacity to reset: sleep architecture, autonomic regulation, parasympathetic activity, and the felt sense of being restored or not.
Wearables capture pieces of recovery through heart rate variability, sleep-stage estimation, and skin temperature. Subjective measurement captures what wearables can't — whether your nervous system has actually downshifted, whether you have capacity for the day ahead. Together they give a more complete read than either alone.
Recovery is the domain most strongly tied to allostatic load — the cumulative wear of chronic stress on regulatory systems. When recovery declines week-over-week, even slowly, the body is signaling that load is exceeding restoration. The compound pattern System Overload (mind + recovery) is the earliest reliably-detectable signature of that imbalance.
Read the research on Recovery →Connection measures social bonds, belonging, and relational health.
The clinical evidence is striking: prolonged social isolation produces health risks comparable to chronic smoking. Loneliness predicts depression and cardiovascular disease across longitudinal cohorts. Conversely, even brief positive social contact produces measurable benefits to stress physiology.
Connection is the domain hardest to measure with technology and easiest to underestimate. People often report being "fine" socially while quietly withdrawing. Measured at a daily timescale, the drift becomes visible — usually before the person doing the withdrawing notices. When connection drifts alongside purpose, the compound pattern frequently maps to clinical depression independent of any other domain.
Read the research on Connection →Purpose measures motivation, meaning, and behavioral activation: the felt sense that what you are doing today matters and is worth doing.
Purpose is the domain most often dismissed as soft and least often measured directly — and yet it is among the most predictive in the clinical literature. Eudaimonic well-being (purpose, meaning, engagement) predicts mortality, cognitive decline, and depression independent of other psychological measures. Behavioral activation — engaging with values-aligned action even in the absence of motivation — is one of the most evidence-supported treatments for depression.
A drop in purpose is usually the deepest signature in a Burnout Signature compound pattern. When purpose, mind, and recovery decline together, the clinical literature has a name for that picture.
Read the research on Purpose →The reason for measuring six domains rather than one is that the clinical signatures of stress, allostatic load, and burnout live in the interactions between domains.
When mind and recovery decline together, the pattern is System Overload — a clinical signature of allostatic load.
When mind, purpose, and recovery decline together, the pattern is Burnout Signature — directly mapped to the burnout literature.
When body and movement co-occur, the pattern is the Stress-Bracing Chain — autonomic tension manifesting somatically.
When connection and purpose withdraw together, the pattern looks like depression but responds to behavioral activation rather than the interventions you would choose if you only measured mood.
These patterns are detectable across the six domains only if you are measuring all six. A single-domain wearable cannot see them. The Pulse is built around them.
See the full Pattern Library →The six domains are not rigid categories you check once. They are a daily measurement substrate.
A single check-in is useful as a snapshot. Three days of data begins to reveal a pattern. Seven days makes the pattern readable in language you can act on. Fourteen days is when compound patterns and longitudinal drift become detectable.
The architecture is intentional: in subjective health data, signal lives in the trend, not the snapshot. This is the same logic that makes daily blood-pressure readings more useful than annual ones.
