Hypnos·Rest
Growth happens in stillness. The metal must cool to harden.
Sleep stage tracking, HRV and RHR trends, recovery scoring, and VO2 Max — pulled from Apple Health and synthesized into actionable insight. SomaForge doesn't just count hours. It understands recovery.
The Research
Sleep is not optional. It's the foundation.
The science is unambiguous. Recovery quality determines training output, hormonal health, injury resilience, and body composition. These are not opinions.
10-15%
One week of restricted sleep reduces testosterone by 10-15%.
Leproult & Van Cauter, JAMA 2011
HRV
HRV is among the strongest non-invasive predictors of recovery readiness.
Plews et al., Int J Sports Physiol Perform 2013
1.7x
Sleep deprivation increases injury risk by 1.7x.
Milewski et al., J Pediatr Orthop 2014
GH
The majority of growth hormone is released during deep sleep.
Van Cauter et al., Sleep 2000
The Problem
Hours slept is not recovery.
Apple Health shows you slept 7 hours. It doesn't tell you that your HRV dropped 20% because you trained legs, drank at dinner, and skipped magnesium.
It doesn't tell you that your RHR has been creeping up for two weeks — the same two weeks your training volume spiked 30%.
Sleep trackers count hours. They don't understand recovery.
What Hypnos Tracks
The full picture of recovery.
Five data streams from Apple Health, synthesized into one recovery picture. Every metric contextualized by training load, medication timing, and nutrition.
Sleep Stage Tracking
Deep, REM, light, and awake stages pulled directly from Apple Health. See the architecture of your sleep, not just the duration.
HRV Trends
Heart rate variability tracked over days, weeks, and months. The single best window into your autonomic nervous system and recovery state.
Resting Heart Rate
Daily RHR trends that reveal overtraining, illness onset, and adaptation. A rising baseline is a signal most people miss.
Recovery Scoring
Synthesizes sleep quality, HRV, and RHR into a single recovery score. Know at a glance whether today is a push day or a pull-back day.
VO2 Max & SpO2
Aerobic fitness estimation and blood oxygen saturation from Apple Health. Long-term cardiovascular health markers that contextualize everything else.
Connected Intelligence
Recovery doesn't exist in isolation.
Hypnos connects to every other pillar in SomaForge. Training, medication, nutrition — they all shape your recovery, and recovery shapes them all back.
Soma's training readiness score starts here. If your recovery score is 40%, Hypnos tells you: don't chase a PR today. The forge needs to cool before the next strike.
Pharmakon logs melatonin at 11pm. Hypnos shows deep sleep increased 22% on melatonin nights. Nous surfaces the pattern and refines the recommendation.
Trophe shows caffeine intake after 2pm. Hypnos shows a deep sleep drop on those nights. Nous flags the correlation so you don't have to guess.

The forge fires burn hot. But the metal must cool.
Rest is not weakness — it's where the transformation happens.
