S · Sleep & Recovery
The first base. The first axis.
Without sleep, every other axis decays. The equation begins here.
Definition
What this axis measures.
Verified duration, sleep architecture, recovery readiness. Measured continuously by your wearables. Verified against clinical norms.
Signals
The data that feeds it.
REM cycles
Per night, by stage and timing.
Deep sleep
Slow-wave time, the body's repair window.
HRV at wake
Vagal recovery overnight.
Sleep latency
Minutes to first sleep onset.
Where it sits
In the equation.
CH = (S × Sp)C × (T + E)p × (ER × RS)(C/3)
S sits in the science-spirit base, paired with Sp. (S × Sp) raised to C. Sleep without practice is a body without intention. Practice without sleep is intention without ground.
Science
What we lean on.
Established sleep medicine (Walker, Czeisler, Buysse). REM and slow-wave both required. Less than seven hours over weeks correlates with significant CH decay.
