ER · Environmental Resonance
Where you live. What you breathe. What you sleep in.
Air quality, light exposure, the exposome. The axis that begins outside your skin.
Definition
What this axis measures.
Environmental inputs aggregated. Measured through location-aware air quality, light timing, water source, occupational exposure, and built-environment factors.
Signals
The data that feeds it.
AQI exposure-weighted
Hours per day above thresholds.
Light timing
Morning bright, evening dim.
Indoor air
VOC, particulate, humidity, CO2.
Occupational
Shift, commute, chemical exposure.
Where it sits
In the equation.
CH = (S × Sp)C × (T + E)p × (ER × RS)(C/3)
ER sits with RS in the relational-environmental base. (ER × RS)^(C/3). The base raised by C divided by three — meaning environment and connection are amplified by mastery, but more gently.
Science
What we lean on.
Exposome research has matured. AQI is now well-correlated with cardiovascular and cognitive outcomes. Light timing dominates circadian alignment, which feeds back into S.
