Human beings regulate physiological state, emotional expression, interpersonal relationships, cultural identity, and civilizational stability through a set of layered rhythmic processes that operate across multiple scales of organization. This paper introduces the Coherence Cascade, a cross-disciplinary framework describing how slow biological rhythms — including digestive motility, respiration, cardiac oscillation, and immune-state cycling — serve as waveguides for faster adaptive processes, such as interoception, emotional regulation, cognition, social entrainment, and cultural synchronization. We describe hinductance as the evolutionary principle by which new functional layers emerge through the entrainment and re-patterning of older rhythmic structures, rather than by replacement. Using evidence from physiology, developmental neuroscience, psychophysiology, anthropology, and chronobiology, we show that coherence depends on the temporal alignment of rhythms across individual, relational, group, cultural, and ecological dimensions. Loss of coherence — driven by chronic stress, trauma, social fragmentation, and digital acceleration — produces dysregulation at the levels of physiology, affect, identity, and governance. We propose a multi-level strategy for restoring coherence that begins with slow-rhythm stabilization (breath, posture, rest, circadian alignment), expands through co-regulation and collective ritual, and culminates in institutional and ecological tempo realignment. The framework provides actionable guidance for clinical practice, education, public health, organizational leadership, and cultural policy, supporting the emergence of a coherence-first regenerative civilization.
