The HumanOS Research Vault indexes 62 canonical sources and 57 normalized evidence records across 4 independent shards. Each public claim still needs source-level editorial review before it can be treated as guidance.
Multimodal interpersonal synchrony: systematic review and meta-analysis
Neural and behavioral synchrony showed a moderate association (r = 0.32); physiological and behavioral synchrony showed a smaller association (r = 0.18). Neural–physiological findings were inconsistent.
Brief structured respiration practices enhance mood and reduce physiological arousal
Daily five-minute breathwork improved mood and reduced respiratory rate in this study; cyclic sighing showed a larger positive-affect change than mindfulness meditation.
Context & study limits
Design
Randomized study comparing brief breathwork with mindfulness meditation
Sample
108 adults enrolled
Limits
Brief breathwork may help with stress management; it is not a substitute for mental-health care.

The impact of food order on postprandial glycaemic excursions in prediabetes
Eating protein and vegetables before carbohydrate lowered the incremental glucose peak and glucose area under the curve in this small, short-term study.
Context & study limits
Design
Random-order, three-meal crossover study
Sample
15 adults with prediabetes
Limits
Results from one meal in 15 people should not be generalized into individual clinical advice.

Human physiological responses to immersion into water of different temperatures
During 14°C immersion, plasma noradrenaline and dopamine rose in the measured group. The paper does not report a three-hour plateau or a 'zero crash' effect.
Context & study limits
Design
One-hour head-out immersion physiology study
Sample
A small group of young men
Limits
Cold immersion has cardiovascular risks and this small physiology study does not establish a general wellness protocol.

Different traditions of truth. Never falsely conflated.
Most wellness platforms pretend that ancestral concepts like Prana or Qi are simply ATP, or they dismiss ancient wisdom entirely. HumanOS maps each knowledge stream with historical authenticity and distinct evidence standards.
