What's Inside
Seven Dimensions of Sleep
Most sleep advice focuses on one variable: hours. This report covers the six dimensions your hours are hiding.
01
Architecture
N1, N2, N3, REM — what each stage actually does and what suppresses it.
02
Depth
Slow-wave sleep, the glymphatic system, and why your brain needs to cleanse itself nightly.
03
Continuity
Why fragmented sleep is cognitively equivalent to 24–30 hours of no sleep.
04
Timing
Chronotype, social jetlag, and the hidden cost of sleeping at the wrong time.
05
Thermal Recovery
Core temperature, thermoregulation, and the room temperature science.
06
Emotional Processing
REM sleep as overnight therapy — what it processes and what breaks down without it.
07
Autonomic Recovery
HRV during sleep — the signal that tells you whether your nervous system actually recovered.
